Embedded SIP Modules for next-GEN Heterogeneous “POWER-Devices”

Abstract

In this paper will focus on the comprehension of System-in-Package (SiP) with embedded active and passive components integration will be described. Embedding of semiconductor chips into substrates provides many advantages that have been noted. It allows the smallest package form-factor with high degree of miniaturization through sequentially stacking of multiple layers containing embedded devices that are optimized for electrical performance with short and geometrically well controlled copper interconnects. In addition, the embedding gives a homogeneous mechanical environment of the chips, resulting in good reliability at system level. Furthermore, embedded technology is an excellent resolution to Power management challenges dealing with new device technologies (Si, GaS, GaN) and optimization on the thermal dissipation with improved efficiency. Embedded technology comes with many challenges in 2019, primarily design for manufacturability (DFM) and maturity. Customers are looking for better-performance capability and pricing normally that means same or lower than die free package cost (DFPC) comparison. This paper will discuss the challenges bring to market the Embedded SIP Modules for next-GEN Heterogeneous “POWER-Devices” Today, the embedded process is being developed by printed circuit board (PCB) manufacturers creating a new supply chain, bringing new players into the semiconductor industry. This new supply chain comes along with new business models. As a result of the increasing interest in implementing embedding technologies, ACCESS Semiconductors in China is committed to be a leader in the adaptation of embedding technologies, with over 10-yrs mature coreless technology and proved design rules for low profile dimensions with seamless Ti/Cu sputtering and Cu pillar interconnect giving advantages in both electrical & power performance. ACCESS Patented “Via-in-Frame” technology provides High Reliability (MSL1, PCT, BHAST) at Cost Effective in high panel utilization for HVM, using standard substrate/PCB known material sets, no need for wafer bumping/RDL, over-mold or under-fill cost adders. ACCESS Semiconductors is currently in HVM on single die 2L, and LVM on multi-devices actives/passives 4L SiP construction both platforms are driven from the power market segment. In-development on Die Last & Frameless (MeSiP) platforms utilizing hybrid technology (mSAP) and Photo Imageable Dielectric (PID) materials for cost down solutions in HVM by Q1FY2020. Also, ACCESS Semiconductors total turn-key solutions will include front-of-line (FOL) and end-of-line (EOL) capability from wafer handling, back-grinding, and dicing with KGD traceability thru the embedded chip process, frame/strip singulation, FT, marking pack & ship providing additional 30% cost reduction in the future. Here's an illustration of Embedded Technology Roadmap and Product Platforms.
