Description
BACKGROUND
1. Technical Field

The present disclosure relates to a package structure, and more particularly, to an electronic package with an offset suppression layer and a manufacturing method thereof.


2. Description of Related Art

When the semiconductor chip on the glass substrate is performed with high-temperature molding or curing process of the encapsulant, since the coefficient of thermal expansion (CTE) of the glass substrate is much less than the coefficient of thermal expansion of the encapsulant (for instance, the coefficient of thermal expansion of the glass substrate and the coefficient of thermal expansion of the encapsulant are 0.3 ppm/K and 7 ppm/K respectively), the glass substrate will expand outward when the encapsulant is heated and shrink inward when the encapsulant is cooled, causing the semiconductor chip to offset by an outward expansion amount as the glass substrate expands outward and offset by an inward shrinkage amount as the glass substrate shrinks inward.


Furthermore, since the coefficient of thermal expansion of the glass substrate (such as 0.3 ppm/K) and the coefficient of thermal expansion of the encapsulant (such as 7 ppm/K) do not belong to the same grade, the outward expansion amount and inward shrinkage amount of the semiconductor chip on the glass substrate are not the same or are largely different, so that the semiconductor chip will offset (for example, the semiconductor chip cannot back to the original position), thereby causing the yield loss of the semiconductor package.



FIG. 1A to FIG. 1C are schematic cross-sectional views illustrating a method of manufacturing a conventional semiconductor package 1.


As shown in FIG. 1A, first, two semiconductor chips 12 are respectively disposed on a glass substrate 10 having a first length L1 via an adhesive layer 11. Each of the semiconductor chips 12 can have an active surface 12a, an inactive surface 12b and a side surface 12c. A plurality of electrode pads 12d may be formed on the active surface 12a of the semiconductor chip 12, and an initial position of the semiconductor chip 12 (such as the side surface 12c) is a first position P1.


As shown in FIG. 1B, when the semiconductor chip 12 on the glass substrate 10 is performed with high-temperature molding or curing process of an encapsulant 13 (e.g., a packaging colloid), the glass substrate 10 will expand outward from the first length L1 (see FIG. 1A) to a second length L2 according to an outward expansion direction A1 when the encapsulant 13 is heated, and the semiconductor chip 12 will offset from the first position P1 (initial position) to a second position P2 as the outward expansion of the glass substrate 10, and the first position P1 and the second position P2 of the semiconductor chip 12 differ by an outward expansion amount B1 (such as the first offset distance).


As shown in FIG. 1C, when the encapsulant 13 is cooled, the glass substrate 10 will shrink inward from the second length L2 (see FIG. 1B) to a third length L3 according to a contraction direction A2 (e.g., an inward shrinkage direction), and the semiconductor chip 12 will offset from the second position P2 to a third position P3 as the inward shrinkage of the glass substrate 10, and the second position P2 and the third position P3 of the semiconductor chip 12 differ by an inward shrinkage amount B2 (such as the second offset distance).


In other words, in the conventional semiconductor package 1, the coefficient of thermal expansion of the glass substrate 10 (such as 0.3 ppm/K) is much less than the coefficient of thermal expansion of the encapsulant 13 (such as 7 ppm/K), such that the coefficient of thermal expansion of the glass substrate 10 and the coefficient of thermal expansion of the encapsulant 13 do not belong to the same grade. As a result, the outward expansion amount B1 and the inward shrinkage amount B2 of the semiconductor chip 12 on the glass substrate 10 are not the same or are largely different, so that the semiconductor chip 12 offsets (for example, the semiconductor chip 12 cannot back to the initial position or the first position P1), thereby causing the yield loss of the semiconductor package 1.


Therefore, there is a need for a solution that addresses the aforementioned shortcomings in the prior art.

In this way, the offset suppression effect of the first electronic element and the second electronic element on the offset suppression layer during the molding or curing process of the encapsulant can be achieved, thereby avoiding the offset of the first electronic element and the second electronic element caused by a large difference in coefficient of thermal expansion of different materials or the coefficient of thermal expansion of the first electronic element and the coefficient of thermal expansion of the second electronic element not belonging to the same grade.

For example, the first electronic element 24 and the second electronic element 25 are bonded to different positions on the first surface 21a of the offset suppression layer 21 via a first adhesive layer 22 and a second adhesive layer 23 respectively.


In one embodiment, the carrier 20 can be a glass substrate, a semiconductor substrate, a silicon substrate, etc., and the carrier 20 can also be a carrier unit of other types that can carry the first electronic element 24 and the second electronic element 25, such as a wafer, a silicon interposer, or a board of other types, etc., but the present disclosure is not limited to as such.


In one embodiment, the first electronic element 24 or the second electronic element 25 can be an active element, a passive element, or a combination of the active element and the passive element. For example, the active element is a semiconductor chip, and the passive element is a resistor, a capacitor, or an inductor.


In one embodiment, the first electronic element 24 can be a semiconductor chip and has an active surface 24a, an inactive surface 24b opposing the active surface 24a, and side surfaces 24c connecting the active surface 24a and the inactive surface 24b.

In one embodiment, the offset suppression layer 21 can be made of polyimide (PI) material, wherein the offset suppression layer 21 made of polyimide material can be formed or coated on the first side 20a of the carrier 20, and the coefficient of thermal expansion of the offset suppression layer 21 (e.g., 4 ppm/K) can be equal or close to the coefficient of thermal expansion of the encapsulant 26 (e.g., 7 ppm/K), so that the coefficient of thermal expansion of the offset suppression layer 21 is in the same grade as the coefficient of thermal expansion of the encapsulant 26.


In one embodiment, the coefficient of thermal expansion of the offset suppression layer 21 (e.g., 4 ppm/K) and the coefficient of thermal expansion of the encapsulant 26 (e.g., 7 ppm/K) are equal or close, so that the “outward expansion amount” of the first electronic element 24 and the second electronic element 25 on the offset suppression layer 21 when the encapsulant 26 is heated and the “inward shrinkage amount” of the first electronic element 24 and the second electronic element 25 on the offset suppression layer 21 when the encapsulant 26 is cooled are equal or close. In this way, the present disclosure can achieve the offset suppression effect of the first electronic element 24 and the second electronic element 25 on the offset suppression layer 21 during the molding or curing process of the encapsulant 26, thereby avoiding the offset of the first electronic element 24 and the second electronic element 25 caused by a large difference in coefficient of thermal expansion of different materials or the coefficient of thermal expansion of the first electronic element 24 and the coefficient of thermal expansion of the second electronic element 25 not belonging to the same grade.
