AIRTIGHT-SEALING PACKAGE MEMBER, PRODUCTION METHOD THEREFOR, AND AIRTIGHT-SEALED PACKAGE PRODUCTION METHOD USING THIS AIRTIGHT-SEALING PACKAGE MEMBER

摘要

The present invention is to provide an hermetic-sealing package member including a substrate and at least one frame-like sealing material for defining a sealing region formed on the substrate, in which the sealing material is formed of a sintered body obtained by sintering at least one metal powder selected from gold, silver, palladium, or platinum having a purity of 99.9 wt% or greater and an average particle size of 0.005 µm to 1.0 µm, and with respect to an arbitrary cross-section toward an outside from the sealing region, a length of an upper end of the sealing material is shorter than a length of a lower end. Examples of a cross-sectional shape of the sealing material may include one formed to have a base portion having a certain height and at least one mountain portion protruding from the base portion or one formed to have a mountain portion having substantially a triangular shape in which the length of the lower end of the sealing material is a bottom. By use of the hermetic-sealing package member of the present invention, a load is reduced at the time of hermetic-sealing and a sufficient sealing effect can be obtained.
