This video explains what a 3D silicon capacitor is. It shows its main benefits in terms of performances and miniaturization.
Murata high-density silicon capacitors are developed with a semiconductor MOS process and are using the third dimension to substantially increase the capacitor surface and thus its capacitance without increasing the capacitor footprint.
Market segments addressed
Networking (RF power and broadband), high reliability, medical, automotive and communications.
