A pseudo-SoC technology incorporating heterogeneous devices has been developed by applying a wafer-level system integration technology. The pseudo-SoC is set up to realize one microchip with heterogeneous devices made by using individual processes for epoxy resin, insulating layer and redistribution layer, respectively. The individual heterogeneous devices are embedded in the epoxy resin to reconfigure the integration wafer. As the insulating layer and redistribution layer are formed by semiconductor wafer process without interposer substrate, the pseudo-SoC enables integration density and signal transmission speed as identical to that of SoC. Also, as the commercial LSI devices and peripheral passive components are able to use for the system integration, the pseudo-SoC enables reduction of time-to-market as identical that of SiP. This paper describes the heterogeneous devices integration technologies and focuses on the pseudo-SoC that overcomes the limitation of system integration and provides the complementary advantages of SiP and SoC with various applications.

This paper reports an advanced process to realize high-quality multiple global layers on high-accuracy chip-redistributed wafer for wafer-level system integration using pseudo-SOC. We have been developing pseudo-SOC (p-SOC) technology by which KGD chips are integrated to a chip-redistributed wafer using high-rigidity epoxy resin and global layers with interconnecting chips are formed on it. The basic process has been established for p-SOC, and integration of MEMS and LSI, or front-end RF LSI and passive components, has been demonstrated. However, the first stage of p-SOC technology was based on a single global layer consisting of an insulating layer and a conductive layer, which limited the range of application. It is desirable to realize high-quality multiple global layers on the high-accuracy chip-redistributed wafer in order to expand its application toward system-level integration. For this purpose, it is necessary to keep all processes at low temperature for the reduction of warpage in the resin-based chip-redistributed wafer during several resin curing processes, to readjust resin-based materials, and to obtain high accuracy of chip position in chip-redistributed wafer. We developed the advanced p-SOC process to resolve these technical issues by improving the hardening process of resin, employing low-temperature-curing polyimide and optimizing the stress analysis by FEM simulation. As a result, realization of a novel one-chip module for a versatile high-sensitivity amplifier is demonstrated.
