The features described herein may be embodied in different forms and are not to be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways of implementing the methods, apparatuses, and/or systems described herein that will be apparent after an understanding of the disclosure of this application.


Throughout the specification, when a component is described as being “connected to,” or “coupled to” another component, it may be directly “connected to,” or “coupled to” the other component, or there may be one or more other components intervening therebetween. In contrast, when an element is described as being “directly connected to,” or “directly coupled to” another element, there can be no other elements intervening therebetween. Likewise, similar expressions, for example, “between” and “immediately between,” and “adjacent to” and “immediately adjacent to,” are also to be construed in the same way. As used herein, the term “and/or” includes any one and any combination of any two or more of the associated listed items.


Although terms such as “first,” “second,” and “third” may be used herein to describe various members, components, regions, layers, or sections, these members, components, regions, layers, or sections are not to be limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or section from another member, component, region, layer, or section. Thus, a first member, component, region, layer, or section referred to in examples described herein may also be referred to as a second member, component, region, layer, or section without departing from the teachings of the examples.


The terminology used herein is for describing various examples only and is not to be used to limit the disclosure. The articles “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes,” and “has” specify the presence of stated features, numbers, operations, members, elements, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, members, elements, and/or combinations thereof.


Unless otherwise defined, all terms, including technical and scientific terms, used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains and based on an understanding of the disclosure of the present application. Terms, such as those defined in commonly used dictionaries, are to be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the disclosure of the present application and are not to be interpreted in an idealized or overly formal sense unless expressly so defined herein. The use of the term “may” herein with respect to an example or embodiment (e.g., as to what an example or embodiment may include or implement) means that at least one example or embodiment exists where such a feature is included or implemented, while all example embodiments are not limited thereto.


However, the disclosure does not have to be configured as limited to the embodiments described below and may be embodied in various other forms.

According to an embodiment, the insulating layer 111 may be a single layer structure. For example, the insulating layer 111 may be a single-layer insulating layer. The plurality of vertical redistribution structures 115 may be embedded in the insulating layer 111. For example, the plurality of vertical redistribution structures 115 may be arranged adjacent to each other in the first horizontal direction (X direction) and the second horizontal direction (Y direction). According to an embodiment, a first fan-in area FI1a may be provided in a first area of the redistribution structure 110 and a second fan-in area FI2a may be provided in a second area of the redistribution structure 110. The first area and the second area may be adjacent to each other in the first horizontal direction (X direction) in a plan view. For example, as shown in FIG. 1A, one side of the redistribution structure 110 is a first fan-in area FI1a, and the other side opposite to the one side is a second fan-in area FI2a, the sides arranged in the first horizontal direction (X direction) in a plan view. In the first fan-in area FI1a of the redistribution structure 110, the plurality of vertical redistribution structures 115 may be arranged side-by-side in the first horizontal direction (X direction) and the second horizontal direction (Y direction), and in the second fan-in area FI2a of the redistribution structure 110, the plurality of horizontal redistribution structures 117 may be arranged side-by-side in the first horizontal direction (X direction) and the second horizontal direction (Y direction).

A distance from an edge of the second semiconductor chip 130 to the first bonding pad 1173 of the horizontal redistribution structure 117 may be distance d1. In a plan view, the first bonding pad 1173 of the horizontal redistribution structure 117 may be outside the second semiconductor chip 130. As such, the second semiconductor chip 130 may not overlap the first bonding pad 1173 of the horizontal redistribution structure 117. The plurality of horizontal redistribution structures 117 and the plurality of vertical redistribution structures 115 are described in detail below.


According to an embodiment, the semiconductor package 10 may further include a seed layer 113 provided on a lower surface and side surfaces of each of vertical redistribution vias 1151 of the vertically redistribution structures 115, and a lower surface and side surfaces of each of the horizontal redistribution vias 1171 of the horizontal redistribution structures 117. For example, the seed layer is formed to cover the lower surface and the side surfaces of each of vertical redistribution vias 1151 of the vertically redistribution structures 115, and the lower surface and the side surfaces of each of the horizontal redistribution vias 1171 of the horizontal redistribution structures 117. For example, the seed layer conformally covers the lower surface and the side surfaces of each of vertical redistribution vias 1151 of the vertically redistribution structures 115, and the lower surface and the side surfaces of each of the horizontal redistribution vias 1171 of the horizontal redistribution structures 117. The seed layer 113 may include a titanium/copper (Ti/Cu) alloy and may prevent metal material of the vertical redistribution vias 1151 and metal material of the horizontal redistribution vias 1171 from diffusing into the insulating layer 111.


For example, the insulating layer 111 may include an insulating material which may include, but is not limited to, silicon oxide, silicon nitride, phosphosilicate glass (PSG), borophosphosilicate glass (BPSG), fluorosilicate glass (FSG), or a combination thereof.


According to an embodiment, the first semiconductor chip 120 may be positioned in the first fan-in area FI1a on the redistribution structure 110. The first semiconductor chip 120 may include a first chip body 121, first chip pads 122, first vertical connection conductors 123, and first chip connection terminals 124.


The first chip body 121 may include an integrated circuit. The integrated circuit may be any kind of integrated circuit including a memory circuit, a logic circuit, or a combination thereof. The memory circuit may include, but is not limited to, a dynamic random access memory (DRAM) circuit, a static random access memory (SRAM) circuit, a flash memory circuit, an electrically erasable and programmable read-only memory (EEPROM) circuit, a phase-change random access memory (PRAM) circuit, a magnetic random access memory (MRAM) circuit, a resistive random access memory (RRAM) circuit, or a combination thereof.

The integrated circuit may include a substrate. The substrate may include a semiconductor material, such as a group IV semiconductor material. a group III-V semiconductor material, a group II-VI semiconductor material, or a combination thereof. The group IV semiconductor material may include, but is not limited to, silicon (Si), germanium (Ge), or a combination thereof. The group III-V semiconductor material may include, but is not limited to, gallium arsenide (GaAs), indium phosphide (InP), gallium phosphide (GaP), indium arsenide (InAs), indium antimony (InSb), indium gallium arsenide (InGaAs), or a combination thereof.

An upper surface of the first vertical connection conductor 123 may be connected to the first chip pad 122, and a lower surface of the first vertical connection conductor 123 may be connected to the first chip connecting terminal 124. For example, the upper surface of the first vertical connection conductor 123 may be physically connected or bonded to the first chip pad 122, and the lower surface of the first vertical connection conductor 123 may be physically connected or bonded to the first chip connecting terminal 124. The first vertical connection conductors 123 may include, for example, a conductive material, such as Cu, Al, Ag, Au, W, Ti, or a combination thereof. The first chip connection terminals 124 may be used to enable self-alignment between the first vertical connection conductors 123 and vertical redistribution pads 1153. The first chip connection terminals 124 may be bonded to the first vertical connection conductors 123 and the vertical redistribution pads 1153 in a molten state, where lines passing through the centers of the first vertical connection conductors 123 may not overlap lines passing through the centers of the corresponding vertical redistribution pads 1153, respectively. However, in the process of solidifying the first chip connection terminals 124 in the molten state, due to the surface tension of the first chip connection terminals 124, the lines passing through the centers of the vertical redistribution pads 1153 may overlap the lines passing through the centers of the first vertical connection conductors 123, respectively. That is, the first chip connection terminals 124 may align the vertical connection conductors 123 so that the centers of the first vertical connection conductors 123 and the centers of the first vertical redistribution pads 1153 coincide without error.


According to an embodiment, the second semiconductor chip 130 may be positioned in the second fan-in area FI2a on the redistribution structure 110.

For example, the through silicon vias 132 may include at least one of Ti, tantalum (Ta), Al, Au, Cu, nickel (Ni), W, titanium nitride (TiN), or tantalum nitride (TaN). However, the disclosure is not limited thereto, and as such, through silicon vias 132 may include other material. Each of the plurality of chips 131 may include a logic semiconductor chip or a memory semiconductor chip. However, all of the plurality of chips 131 need not be of the same type. For example, a lowermost chip among the plurality of chips 131 may be a logic semiconductor chip and the other chips may be memory semiconductor chips. The logic semiconductor chip may include, but is not limited to, an AP, a CPU, or a controller. The memory chip may include, but is not limited to, DRAM, SRAM, PRAM, MRAM, RRAM, flash memory, or EEPROM.


The second vertical connection conductors 133 may be arranged between the lowermost chip among the plurality of chips 131 and the second chip connection terminals 134. A lower surface of the second vertical connection conductor 133 is bonded to the second chip connection terminal 134. The second vertical connection conductors 133 may include, but is not limited to, a conductive material including Cu, Al, Ag, Au, W, Ti, or a combination thereof.


According to an embodiment, the semiconductor package 10 may include a molding layer 150 on the insulating layer 111 to seal the first semiconductor chip 120, the second semiconductor chip 130, the plurality of vertical redistribution structures 115, and the plurality of horizontal redistribution structures 117. According to an embodiment, the molding layer 150 may be provided on side surfaces of the vertical redistribution pads 1153, a side surface of the tracer pattern 1175, and an upper surface and a side surface of the first bonding pad 1173. For example, the molding layer 150 may cover the side surfaces of the vertical redistribution pads 1153, the side surface of the tracer pattern 1175, the upper surface and the side surface of the first bonding pad 1173. The molding layer 150 may include, but is not limited to, a thermosetting resin, a thermoplastic resin, a UV curable resin, or a combination thereof. The molding layer 150 may include, but is not limited to, an epoxy resin, a silicone resin, or a combination thereof. The molding layer 150 may include, but is not limited to, an epoxy mold compound (EMC).


As shown in FIGS. 1A and 1B, the plurality of horizontal redistribution structures 117 may be arranged symmetrically with respect to a centerline crossing the center of the second semiconductor chip 130 in the first horizontal direction (X direction) and a centerline crossing the center of the second semiconductor chip 130 in the second horizontal direction (Y direction). As shown in FIGS. 1A and 1B, the plurality of horizontal redistribution structures 117 may include a first horizontal redistribution structure 117a, a second horizontal redistribution structure 117b spaced apart from the first horizontal redistribution structure 117a in the first horizontal direction (X direction), a third horizontal redistribution structure 117c spaced apart from the first horizontal redistribution structure 117a in the second horizontal direction (Y direction), and a fourth horizontal redistribution structure 117d spaced apart from the third horizontal redistribution structure 117c in the first horizontal direction (X direction). In addition, the fourth horizontal redistribution structure 117d may be spaced apart from the second horizontal redistribution structure 117b in the second horizontal direction (Y direction). The first horizontal redistribution structure 117a and the second horizontal redistribution structure 117b may be arranged on one side with respect to a centerline crossing the center of the second semiconductor chip 130 in the second horizontal direction (Y direction).


According to an embodiment, a first angle θ1 of the first horizontal redistribution structure 117a inclined with respect to the second horizontal direction (Y direction) may be different from a second angle θ2 of the second horizontal redistribution structure 117b inclined with respect to the second horizontal direction (Y direction). As shown in FIG. 1B, since the first horizontal redistribution structure 117a is positioned further outside the second semiconductor chip 130 in a plan view than the second horizontal redistribution structure 117b, the first angle θ1 may be greater than the second angle θ2. However, the first angle θ1 is not necessarily limited thereto, and as such, according to another embodiment, the first angle θ1 may be less than the second angle θ2.


The first horizontal redistribution structure 117a includes a first tracer pattern 1175a extending at the first angle 01 from the second horizontal direction (Y direction), a first bonding pad 1173a which is formed at one end of the first tracer pattern 1175a and does not overlap the second semiconductor chip 130 in a plan view, and a second bonding pad 1177a which is formed at the other end opposite to the one end of the first tracer pattern 1175a and overlaps the second semiconductor chip 130.


The second horizontal redistribution structure 117b includes a second tracer pattern 1175b extending at the second angle θ2 from the second horizontal direction (Y direction), a first bonding pad 1173b which is formed at one end of the second tracer pattern 1175b and does not overlap the second semiconductor chip 130 in a plan view, and a second bonding pad 1177b which is formed at the other end opposite to the one end of the second tracer pattern 1175b and overlaps the second semiconductor chip 130.


The third horizontal redistribution structure 117c includes a third tracer pattern 1175c extending at a third angle θ3 from the second horizontal direction (Y direction), a first bonding pad 1173c which is formed at one end of the third tracer pattern 1175c and does not overlap the second semiconductor chip 130 in a plan view, and a second bonding pad 1177c which is formed at the other end opposite to the one end of the third tracer pattern 1175c and overlaps the second semiconductor chip 130.


The fourth horizontal redistribution structure 117d includes a fourth tracer pattern 1175d extending at a fourth angle θ4 from the second horizontal direction (Y direction), a first bonding pad 1173d which is formed at one end of the fourth tracer pattern 1175d and overlaps the second semiconductor chip 130 in a plan view, and a second bonding pad 1177d which is formed at the other end opposite to the one end of the fourth tracer pattern 1175d and overlaps the second semiconductor chip 130. Since the fourth horizontal redistribution structure 117d is positioned close to the inside of the second semiconductor chip 130 rather than the outside in a plan view, the first bonding pad 1173d of the fourth horizontal redistribution structure 117d and the second bonding pad 1177d of the fourth horizontal redistribution structure 117d may each overlap the second semiconductor chip 130.


According to an embodiment, the vertical redistribution structures 115 and the horizontal redistribution structures 117 may include at least one of Ti, Ta, Al, Au, Cu, Ni, W, TiN, or TaN.


According to an embodiment, the semiconductor package 10 may be redistributed with the single-layered horizontal redistribution structures 117 even without a plurality of conductive patterns and a plurality of conductive vias, thereby reducing process costs. In addition, since the redistribution structure 110 includes only a single-layered insulating layer, warpage may be easily controlled.



FIG. 2A is a plan view of a redistribution structure of a semiconductor package according to an embodiment. FIG. 2B is an enlarged view of a portion P2 of FIG. 2A, and FIG. 2C is a cross-sectional view taken along a line C-C′ of FIG. 2A.


Referring to FIGS. 2A to 2C, a semiconductor package 11 shown in FIGS. 2A to 2C is substantially the same as or similar to the semiconductor package 10 shown in FIGS. 1A to 1D except that the arrangement of a plurality of horizontal redistribution structures 217 is different from that of the plurality of horizontal redistribution structures 117 shown in FIGS. 1A to 1D. Therefore, a description of the components already mentioned with reference to FIGS. 1A to 1D is omitted.


As shown in FIG. 2C, a first bonding pad 2173 of the horizontal redistribution structure 217 may be located closer to the center of the second semiconductor chip 130 than a second bonding pad 2177.
