Publication number: 20240107780Abstract: A system on chip (SoC) die package is attached to a redistribution structure of a semiconductor device package such that a top surface of the SoC die package is above a top surface of an adjacent memory die package. This may be achieved through the use of various attachment structures that increase the height of the SoC die package. After encapsulating the memory die package and the SoC die package in an encapsulation layer, the encapsulation layer is grinded down. The top surface of the SoC die package being above the top surface of the adjacent memory die package results in the top surface of the SoC die package being exposed through the encapsulation layer after the grinding operation. This enables heat to be dissipated through the top surface of the SoC die package.Type: ApplicationFiled: January 5, 2023Publication date: March 28, 2024Inventors: Chih-Wei WU, Ying-Ching SHIH, Wen-Chih CHIOU, An-Jhih SU, Chia-Nan YUAN
