Package structure of wafer-level system-in-package

Abstract

A wafer-level system-in-package (WLSiP) package structure is provided. The WLSiP package structure includes a device wafer, an adhesive layer, and a plurality of second chips. The device wafer includes a first front surface having a plurality of first chips integrated therein and a first back surface opposing the first front surface. The adhesive layer is formed on the first front surface of the device wafer and the adhesive layer includes a plurality of through-holes exposing the first front surface. The plurality of second chips are bonded to the device wafer, and the plurality of second chips are bonded with the adhesive layer to cover the plurality of first through-holes in a one-to-one correspondence.

Dependencies are inferred from the claim text.
