What is SoIC?

SoIC is a key technology pillar to advance the field of heterogeneous chiplets integration with reduced size, increased performance. It features ultra-high-density-vertical stacking for high performance, low power, and min RLC (resistance-inductance-capacitance). SoIC integrates active and passive chips into a new integrated-SoC system, which is electrically identical to native SoC, to achieve better form factor and performance.

The key features of SoIC technology include:

1. Enables the heterogeneous integration (HI) of known good dies (KGDs) with different chip sizes, functionalities and wafer node technologies.

   (a) SoC before chip partition; (b), (c), (d) Variant partitioned chiplets and re-integrated schemes enabled by SoIC technology

   
2. Exceptional scalability

   With the innovative bonding scheme, SoIC technology enables the strong bonding pitch scalability for chip I/O to realize a high density die-to-die interconnects. The bond pitch starts from sub-10 µm rule. Short die-to-die connection has the merits of smaller form-factor, higher bandwidth, better power integrity (PI), signal integrity (SI), and lower power consumption comparing to the current industry state-of-the-art packaging solutions.

   
3. Holistic 3D System Integration

   SoIC technology integrates both homogeneous and heterogeneous chiplets into a single SoC-like chip with a smaller footprint and thinner profile, which can be holistically integrated into advanced WLSI (aka CoWoS^® service and InFO). From external appearance, the newly integrated chip is just like a general SoC chip yet embedded with desired and heterogeneously integrated functionalities.
