Abstract

Official abstract text for this publication.

A wafer level package has a first wafer having a plurality of chips mounted or formed thereon in a plane, and a second wafer that is opposed to the first wafer. The first wafer and the second wafer are joined while a seal frame that seals a periphery of each chip is interposed therebetween. A gap is formed between the seal frames of the chips adjacent to each other. A partial connect part that partially connects the seal frames to each other is provided in the gap formed between the seal frames of the chips adjacent to each other.
