摘要:
A semiconductor chip includes stress-relief to mitigate the effects of differences in coefficients of thermal expansion (CTE) between a printed circuit board (PCB) and a semiconductor chip and a flip-chip package including the semiconductor chip. The semiconductor chip includes a stress-relief buffer coupling a bump and a semiconductor chip pad.
摘要:
Embodiments of the inventive concept include a semiconductor package having a plurality of stacked semiconductor chips. A multi-layered substrate includes a central insulation layer, an upper wiring layer disposed on an upper surface of the central insulation layer, and a first lower wiring layer disposed on a lower surface of the central insulation layer. The stacked semiconductor chips are connected to the multi-layered substrate and/or each other using various means. The semiconductor package is capable of high performance operation, like a semiconductor package based on flip-ship bonding, and also meets the need for large capacity by overcoming a limitation caused by a single semiconductor chip. Embodiments of the inventive concept also include methods of manufacturing the semiconductor package.
摘要:
A stack type semiconductor package, and a method of fabricating the same are provided. The stack type semiconductor package may include a lower unit package and an upper unit package. The lower unit package may include a substrate, and a semiconductor chip on an upper surface of the substrate. A bump may be on an upper surface of the substrate, and a protecting layer, covering the semiconductor chip, may be formed. The protecting layer may include a via hole partially exposing the bump. The upper unit package may be on the protecting layer, and may include an internal connection solder ball on a lower surface of the upper unit package. The internal connection solder ball may be inserted into the via hole and connected to the bump.
