The disclosures herein generally relate to a gas barrier laminate, a semiconductor device, a display element, a display device, and a system.
A high level of gas barrier property is demanded for the substrate in the fields of electronic devices such as displays, lighting devices, and solar batteries, in addition to several physical properties including transparency, heat resistance, solvent resistance, and interlayer adhesion. For this reason, the provision of a barrier layer having a gas barrier property between the substrate and a semiconductor element is studied.
As an example of obtaining a gas barrier property, there is a technique of depositing a resin layer containing a main component of polyorganosilsesquioxane on at least one of plastic films, and forming an inorganic compound layer including any one of silicon oxide, silicon oxide/nitride, oxidized silicon carbide, silicon carbide, silicon nitride, and silicon dioxide in the resin layer, so as to obtain a gas barrier laminate (for example, see Japanese Unexamined Patent Application Publication No. 2006-123307).
In one embodiment, a gas barrier laminate includes a substrate and a barrier layer formed on at least one of faces of the substrate. The barrier layer includes composite oxide including silicon and alkaline-earth metal.
It is a general object of at least one embodiment of the present invention to provide a gas barrier laminate, a semiconductor device, a display element, a display device, and a system that substantially obviate one or more problems caused by the limitations and disadvantages of the related art.
In the following, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, identical components have identical numerical references, and overlapping description is omitted, in some cases.
The substrate 11 is an insulating member, and serves as a base body for forming the barrier layer 12. The shape, structure, and size of the substrate 11 are not particularly limited, and may be selected for the purpose as needed. The material of the substrate 11 is not particularly limited. The material of the substrate 11 may be either a rigid material or a flexible material (i.e. a material having flexibility), and may be selected for the purpose as needed. Specific examples will be given as follows.
For example, a glass substrate or a plastic substrate can be used for the substrate 11. There is no particular limitation to the glass substrate, and any glass substrate may be selected for the purpose as needed. Examples of the glass substrate may include, but are not limited to, alkali-free glass, and silica glass. There is no particular limitation to the plastic substrate, and any plastic substrate may be selected for the purpose as needed. Examples of the plastic substrate may include, but are not limited to, polycarbonate (PC), polyimide (PI), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN).
The barrier layer 12 is formed on at least one of faces of the substrate 11. The barrier layer 12 may be formed on both faces of the substrate 11. The barrier layer 12 is a layer that blocks the flow of gas (i.e., gaseous substance) such as oxygen or water vapor. For example, when semiconductor elements are mounted on the barrier layer 12, the barrier layer 12 prevents oxygen or water vapor from reaching the semiconductor elements from the substrate 11 side. There is no particular limitation to the average thickness, and any average thickness of the barrier layer 12 may be selected for the purpose as needed.
The barrier layer 12 includes composite oxide containing silicon and alkaline-earth metal. Such a barrier layer 12 improves the linear expansion coefficient more than the linear expansion coefficient of a known barrier layer including SiO2. Therefore, the barrier layer 12 is achieved that hardly suffers from minute defects such as cracks, peelings, and pin holes, which are caused by, for example, expansion and contraction of the substrate 11 in accordance with a change in temperature. In addition, as being excellent in transparency and heat resistance, the composite oxide including silicon and alkaline-earth metal is applicable to a semiconductor device, for example, a thin-film transistor.
The alkaline-earth metal included in the composite oxide can be, for example, at least one of Al, B, Mg, Ca, Sr, and Ba. Alternatively, the composite oxide can include some (or all) Al, B, Mg, Ca, Sr, and Ba. The composite oxide may include at least one of Al and B.
Herein, as an example of using a gas barrier laminate, a field-effect transistor produced on the gas barrier laminate will be described.
In the field-effect transistor 20, the active layer 21 is formed on the barrier layer 12 having an insulating property, in the gas barrier laminate 10. The source electrode 22 and the drain electrode 23 are formed on the active layer 21 so as to form a channel in the active layer 21. The gate insulating layer 24 is formed to cover the active layer 21, the source electrode 22, and the drain electrode 23. The gate electrode 25 is formed on the gate insulating layer 24. Hereinafter, the component elements of the field-effect transistor 20 will be described in detail.
In the present embodiment, for the sake of simplicity, the gate electrode 25 side is referred to as an upper side or a first side, whereas the substrate 11 side is referred to as a lower side or a second side. In addition, the face on the gate electrode 25 side in each layer is referred to as an upper side or a first side, whereas the face on the substrate 11 side is referred to as a lower side or a second side. The field-effect transistor 20 can also be used upside down, or can be arranged at any angle. In addition, a planar view means a view when a target object is viewed in the normal direction of the upper face of the substrate 11. A planar shape means a shape when the target object is viewed in the normal direction of the upper face of the substrate 11. Further, a longitudinal section means a section taken along a stacked direction of the layers on the substrate 11. A transverse section means a section taken along a perpendicular direction to the stacked direction of the layers on the substrate 11 (i.e., a direction parallel to top face of the substrate 11).
The active layer 21 is formed in a given region of the barrier layer 12. The active layer 21 can be a layer including, for example, an oxide semiconductor. With regard to oxide semiconductor, for example, an n-type oxide semiconductor can be used. In this case, there is no particular limitation to the n-type oxide semiconductor, and any n-type oxide semiconductor may be selected for the purpose as needed. Examples of the n-type oxide semiconductor may include, but are not limited to, an Mg—In based oxide semiconductor and an In based oxide semiconductor. There is no particular limitation to the average thickness, and any average thickness of the active layer 21 may be selected for the purpose as needed. The average thickness of the active layer 21 may be 1 nanometer to 200 nanometers. The average thickness of the active layer 21 may be 5 nanometers to 100 nanometers.
The source electrode 22 and the drain electrode 23 are formed on the barrier layer 12. The source electrode 22 and the drain electrode 23 partially cover the active layer 21. The source electrode 22 and the drain electrode 23 are spaced apart from each other at a given interval for a channel region. The source electrode 22 and the drain electrode 23 make electrical current available in accordance with the gate voltage applied to the gate electrode 25. Together with the source electrode 22 and the drain electrode 23, interconnections to be respectively coupled to the source electrode 22 and the drain electrode 23 are formed on the same layer.
There is no particular limitation to the materials for the source electrode 22, the drain electrode 23, and the interconnections, and any material may be selected for the purpose as needed. Examples of the material may include, but are not limited to, metals such as Al, Au, Pt, Pd, Ag, Cu, Zn, Ni, Cr, Ta, Mb, Ti, alloys of these metals, and mixtures of these metals. Alternatively, conductive oxide such as indium oxide, zinc oxide, tin oxide, gallium oxide, niobium oxide, a complex compound of those conductive oxides, or a mixture of those oxides can be used.
There is no particular limitation to the average thicknesses of the source electrode 22, the drain electrode 23, and the interconnections, and any average thickness may be selected for the purpose as needed. The average thicknesses of the source electrode 22, the drain electrode 23, and the interconnections may be 40 nanometers to 2 micrometers. The average thicknesses of the source electrode 22, the drain electrode 23, and the interconnections may be 70 nanometers to 1 micrometer.
The gate insulating layer 24 covers the active layer 21, the source electrode 22, and the drain electrode 23. The gate insulating layer 24 is formed over the barrier layer 12. The gate insulating layer 24 insulates the source electrode 22 and the drain electrode 23 from the gate electrode 25. The material of the gate insulating layer 24 is not particularly limited, and any material may be selected for the purpose as needed. For example, an inorganic insulating material or an organic insulating material can be used.
Examples of the inorganic insulating material may include, but are not limited to, silicon oxide, alumina, tantalum oxide, titanium oxide, yttrium oxide, lanthanum oxide, hafnium oxide, zirconium oxide, silicon nitride, aluminum nitride, and mixtures of the above materials. Examples of the organic insulating material may include, but are not limited to, polyimide, polyamide, polyacrylate, polyvinyl alcohol, and novolak resin. The average thickness of the gate insulating layer 24 is not particularly limited, and any average thickness may be selected for the purpose as needed. The average thickness of the gate insulating layer 24 may be 50 nanometers to 3 micrometers. The average thickness of the gate insulating layer 24 may be 100 nanometers to 1 micrometer.
The barrier layer 12 included in the gas barrier laminate 10 is an insulating layer, and the gate insulating layer 24 may have the same composition as the composition of the barrier layer 12. To be specific, the gate insulating layer 24 may include composite oxide including silicon and alkaline-earth metal.
The barrier layer 12 is in partial contact with the gate insulating layer 24. Both the barrier layer 12 and the gate insulating layer 24 having the same composition improve the adhesion property between the barrier layer 12 and the gate insulating layer 24. In addition, both the barrier layer 12 and the gate insulating layer 24 having the same composition reduce a possibility of a defect produced at a boundary between the barrier layer 12 and the gate insulating layer 24. In particular, in a top-gate field-effect transistor, the barrier layer 12 and the gate insulating layer 24 completely cover the active layer 21. The gas barrier property to block the flow of the active layer 21 is improved, accordingly.
The gate electrode 25 is stacked above the active layer 21 through the gate insulating layer 24. The gate electrode 25 applies a gate voltage. The material of the gate electrode 25 is not particularly limited, and any material may be selected for the purpose as needed. For example, the same material as the material of the source electrode 22 or the drain electrode 23 can be used. The average thickness of the gate electrode 25 is not particularly limited, and any average thickness may be selected for the purpose as needed. The average thickness of the gate electrode 25 may be 40 nanometers to 2 micrometers. The average thickness of the gate electrode 25 may be 70 nanometers to 1 micrometer.

In the above-described processes, the field-effect transistor 20 of a top-gate top-contact type illustrated in
As described above, in the field-effect transistor 20 in the first embodiment, the layers including the active layer 21 are formed on the gas barrier laminate 10. This configuration prevents oxygen or water vapor from reaching the active layer 21 side from the substrate 11 side. As a result, performance degradation of the field-effect transistor 20 is prevented.
In addition, the barrier layer 12 includes the composite oxide including silicon and alkaline-earth metal. This configuration improves the linear expansion coefficient more than the linear expansion coefficient of a known barrier layer made SiO2 and other materials. This configuration also achieves the barrier layer 12 that hardly suffers from minute defects such as cracks, peelings, and pin holes, which are caused by, for example, expansion and contraction of the substrate 11 in accordance with a change in temperature. As a result, degradation in the gas barrier property of the barrier layer 12 is prevented over time. The performance of the field-effect transistor 20 is maintained for a long time.
Further, also in a case where the substrate 11 is a flexible film-shaped substrate, the barrier layer 12 has a high linear expansion coefficient, and follows the expansion and contraction of the substrate 11. Therefore, the barrier layer 12 hardly suffers from a minute defect. As a result, degradation in the gas barrier property of the barrier layer 12 is prevented over time. The performance of the field-effect transistor 20 is maintained for a long time.
In variations of the first embodiment, examples of the field-effect transistor having different layer structures from the structure of the field-effect transistor in the first embodiment will be described. In variations of the first embodiment, descriptions of same components as the components that have been described above are omitted, in some cases.

The field-effect transistor formed on the gas barrier laminate 10 is not limited to a top-gate top-contact field-effect transistor, and may be a top-gate bottom-contact field-effect transistor, a bottom-gate top-contact field-effect transistor, or a bottom-gate bottom-contact field-effect transistor. Also in those cases, the same advantages as the first embodiment are achievable.
In each one of Examples 1 to 4, the barrier layer 12 of the gas barrier laminate 10 illustrated in
The amounts indicated in Table 1 were mixed into a solution containing Tetramethoxysilane (T5702-100G, Aldrich), aluminum (s-butoxide) diacetoacid ester chelate (containing 8.4% of Al, Alfa89349, Alfa Aesar), boric acid triisopropyl (Wako320-41532, Wako Chemical Ltd.), 2-ethylhexanoic acid calcium mineral spirit solution (containing 5% of Ca, Wako351-01162, Wako Chemical Ltd.), and 2-ethylhexanoic acid strontium toluene solution (containing 2% of Sr, Wako 195-09561, Wako Pure Chemical Industries, Ltd.). The mixed solution was then diluted by toluene, and the coating liquid used for forming the barrier layer 12 was obtained. The composite oxide formed with the coating liquid used for forming the barrier layer 12 had compositions indicated in Table 1 below.
The coating liquid of 0.4 milliliters used for forming the barrier layer 12 was applied on the substrate 11. Subsequently, a drying process was conducted in the air at 120 degrees Celsius for one hour. Then, a baking process was conducted under O2 atmosphere at 400 degrees Celsius for three hours. The barrier layer 12 of a composite oxide film including SiO2—Al2O3—B2O3—CaO—SrO was formed. The average thickness of the barrier layer 12 was approximately 30 nanometers. At the end, a heating process was conducted at 320 degrees Celsius for 30 minutes. Then, the appearance was evaluated. The results are indicated in Table 1 below.
Firstly, a lower electrode was formed on the substrate. To be specific, a molybdenum (Mo) film was deposited by DC sputtering through a metal mask to have the average thickness of 100 nanometers. Then, the coating liquid used for forming the barrier layer 12 in each Example was used to form a dielectric layer in the same process as described above. At the end, an upper electrode was formed on the dielectric layer in the same process as the process of forming the lower electrode. Thus, a capacitor was formed. The dielectric layer had the average thickness of approximately 30 nanometers. The capacitor was formed as described above and then the relative permittivity was measured by an LCR meter (4284A, Agilent). The results are indicated in Table 1.
The coating liquid of one liter used for forming the barrier layer 12 in each Example was produced. The solvent was eliminated, a heating process was conducted in a Pt crucible at 1600 degrees Celsius, and melting occurred. Then, a columnar object having a diameter of 5 millimeters and a height of 10 millimeters was produced by a float method. The average linear expansion coefficient of the columnar object in a temperature range of 20 degrees Celsius to 300 degrees Celsius was measured by a thermal mechanical analyzer (8310 series, Rigaku Corporation). The produced columnar object had the same composition as the composition of a case where the coating liquid used for forming the barrier layer 12 was deposited on either one of the faces of the substrate, in each of Examples. The produced columnar object also had the same linear expansion coefficient. The results are indicated in Table 1.
By using SiCl4 as a material, a SiO2 layer was formed on the substrate 11 by a Plasma Enhance Chemical Vapor Deposition (PECVD) process. The SiO2 layer that was formed had the average thickness of approximately 30 nanometers. At the end, a heating process was conducted at 320 degrees Celsius for 30 minutes. Then, the appearance was evaluated. The results are indicated in Table 2 below.
Firstly, a lower electrode was formed on the substrate. To be specific, a molybdenum (Mo) film was deposited by DC sputtering through a metal mask to have the average thickness of 100 nanometers. Then, a dielectric layer including a SiO2 layer was formed in the same process as the process in each of Examples. At the end, an upper electrode was formed on the dielectric layer in the same process as the process of forming the lower electrode, and thus a capacitor was formed. The dielectric layer had the average thickness of approximately 30 nanometers. The capacitor was formed as described above and then the relative permittivity was measured by an LCR meter (4284A, Agilent). The results are indicated in Table 2 below.
By using SiCl4 as a material, a hydrolysis process was conducted in oxyhydrogen flame to grow silica powder, and a SiO2 porous body was obtained. Then, the SiO2 porous body was melted at high temperature of 1600 degrees Celsius. Columnar SiO2 glass having a diameter of 5 millimeters and a height of 10 millimeters was produced. The average linear expansion coefficient of the produced columnar SiO2 glass in the temperature range of 20 degrees Celsius to 300 degrees Celsius was measured by the thermal mechanical analyzer (8310 series, Rigaku Corporation). The results are indicated in Table 2.
As indicated in Table 1 and Table 2, in the comparative example, the linear expansion coefficient was 5×10−7/K and peeling occurred. However, in Examples 1 to 4, the linear expansion coefficient was 24.7×10−7/K at the lowest and peeling did not occur.
In other words, the barrier layer 12 including the composite oxide including silicon and alkaline-earth metal has approximately five times or more the linear expansion coefficient of the SiO2 layer in the comparative example. These results exhibit that the barrier layer 12 in Examples 1 to 4 hardly suffers from minute defects such as cracks, peelings, and pin holes, which are caused by, for example, expansion and contraction of the substrate in accordance with a change in temperature. In other words, the barrier layers 12 in Examples 1 to 4 are capable of preventing degradation in the gas barrier property.
