Silicon capacitors embedded within RDL interposers provide low-impedance power delivery paths for AI accelerators and high-performance computing platforms.
Why Silicon Capacitors?
Embedded within RDL interposers, silicon capacitors provide ultra-low-impedance power delivery networks for AI processors and HPC platforms. By suppressing power noise and minimizing voltage fluctuations, they significantly improve power integrity (PI) and signal integrity (SI), meeting the demanding performance requirements of next-generation high-computing systems.
Challenges of Traditional MLCCs
Limitations- Higher ESL limits transient current delivery for AI processors
- Significant DC Bias effects reduce effective capacitance under load
- Larger package sizes prevent integration within interposers or near-die locations
- Longer power paths increase impedance and degrade power integrity
