Abstract

A multi-chip semiconductor device with multi-level structure including a substrate with a top substrate surface, a cavity with a depth in the substrate, a first chip having a top first chip surface with a first chip height, optionally including a second chip having a top second chip surface with a second chip height, and a connecting passive chip bridging the first chip, the second chip and the substrate by solder bumps wherein the solder bumps enable the connecting passive chip to be level.
