SoIC Advanced Packaging Applications
SoIC (System on Integrated Chips) technology is one of the key innovations in advanced semiconductor packaging. By utilizing Chip-to-Chip (C2C) and Chip-to-Wafer (C2W) 3D stacking technologies, SoIC enables higher performance, lower power consumption, and greater bandwidth through advanced system-level integration.
Compared with conventional packaging technologies, SoIC offers significant advantages, including ultra-high interconnect density, extremely short signal paths, enhanced electrical performance, and superior thermal management capabilities. It is widely adopted in applications such as Artificial Intelligence (AI), High-Performance Computing (HPC), Data Centers, 5G communications, and automotive electronics.
At Zhanyang, we provide comprehensive SoIC packaging process core components and precision fixture solutions to support high-precision 3D stacking manufacturing. Leveraging our expertise in semiconductor processing, precision machining, advanced materials, and packaging integration technologies, we help customers achieve higher alignment accuracy, improved package reliability, enhanced thermal performance, and stable high-volume production for next-generation semiconductor devices.
SoIC Packaging Process Flow
The SoIC process mainly consists of the following key steps:
Wafer Fabrication
● Fabrication of logic and memory devices
Wafer Thinning
● Reduce wafer thickness to less than 50 μm to enable 3D stacking
Alignment & Bonding
● Die-to-Die Bonding
● Die-to-Wafer Bonding
● Alignment accuracy requirement of less than 1 μm (sub-micron level)
Hybrid Bonding
● Combines Cu-to-Cu interconnects with dielectric bonding technology
Back-End Processing
● Final packaging and testing
SoIC Process Technical Challenges
- Sub-Micron Alignment: Alignment errors must be controlled within 1 μm or even nanometer-level tolerances.
- Wafer Warpage: Thin wafers are highly susceptible to deformation during processing.
- CTE Mismatch: Differences in the coefficient of thermal expansion among materials can lead to stress concentration.
- Bonding Voids: Defects at the bonding interface can affect electrical performance and long-term reliability.
- Ultra-Thin Die Handling: Dies thinner than 50 μm are extremely fragile and prone to cracking.
As a result, demand for high-precision Bond Tools, highly stable stages, and precision fixture designs continues to increase significantly.
