ww5 high-density silicon capacitors have been developed with a semiconductor MOS process and are using 3D structures to substantially increase the electrode surfaces, and therefore increase the capacitance for a given footprint. ww5 silicon technology is based on a monolithic structure embedded in a noncrystalline substrate (single MIM and multi-MIM – Metal Insulator Metal).
Market segments addressed Networking (RF power and broadband), high reliability, medical, automotive and communications.
This video explains what a silicon capacitor is. It shows its main benefits in terms of performances and miniaturization.
Silicon capacitors have very low insertion loss even at very high frequencies and are very small in size, which helps to reduce the power consumption and mounting area of ultra broadband optical communication devices.
With silicon capacitors, IMD generated in PAMs, an issue for the broader signal frequency bandwidths for high-speed and high-capacity communications, can be removed to prevent the degradation of signal integrity.
For LiDAR, the sensing technology that makes autonomous driving possible for which demand has been rapidly increasing in recent years, the low ESL characteristics of silicon capacitors allow for longer detection distances and improved measurement resolution.
We also offer custom integrated passive devices (IPDs) for medical devices. Silicon IPDs allow for highly integrated systems, higher performance, lower energy consumption, and higher reliability.
