INTEGRATION OF INDUCTORS WITH ADVANCED-NODE SYSTEM-ON-CHIP (SOC) USING GLASS WAFER WITH INDUCTORS AND WAFER-TO-WAFER JOINING

Abstract:

A voltage regulator having a coil inductor is integrated or embedded in a system-on-chip (SOC) device. The coil inductor is fabricated on an inductor wafer with through vias, and the inductor wafer is joined with an SOC wafer for integration with the SOC device.
