Abstract

Official abstract text for this publication.

A method of forming a semiconductor device having through molding vias comprises eutectic bonding a capping wafer and a base wafer to form a wafer package. The base wafer comprises a first chip package portion, a second chip package portion, and a third chip package portion. The capping wafer comprises a plurality of isolation trenches and a plurality of separation trenches having a depth greater than the isolation trenches with respect to a same surface of the capping wafer. The method also comprises removing a portion of the capping wafer exposing a first chip package portion contact, a second chip package portion contact, and a third chip package portion contact. The method further comprises separating the wafer package to separate the wafer package into a first chip package, a second chip package, and a third chip package.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method of forming a semiconductor device comprising: eutectic bonding a capping wafer and a base wafer to form a wafer package, wherein the base wafer comprises a first chip package portion, a second chip package portion, and a third chip package portion, and the capping wafer comprises a plurality of isolation trenches, the plurality of isolation trenches being configured to substantially align with a corresponding trench region of one of the first…
