  • Method of hermetically encapsulating a semiconductor device by laser irradiation
    Patent number: 4400870
    Abstract: A hermetic seal is formed without expensive precious metals by fusing two members of a semiconductor package together by scanning a laser beam along adjacent edges of the members. The compositions of the members which are fused together include ceramic, glass and metal. The method enables the formation of a hermetic seal at a relatively low temperature thereby greatly reducing the thermal stress on the semiconductor chip with resulting improvement in yields.
