  • Micro-electro-mechanical system (MEMS) package having metal sealing member
    Publication number: 20060076670
    Abstract: A micro-electro-mechanical system (MEMS) package having a metal sealing member is disclosed. The MEMS package is formed by forming a metal layer on a substrate by patterning so that the metal layer surrounds an MEMS element provided on the substrate; joining a lid to the metal layer; providing a side sealing member on a side surface of the substrate; and covering the lid and the substrate with a metal sealing member, thus hermetically sealing the MEMS element from the external environment.
