  • Method for packaging a microelectronic device in a hermetically sealed cavity and managing the atmosphere of the cavity with a dedicated hole
    Patent number: 9908773
    Abstract: A method for packaging a microelectronic device in an hermetically sealed cavity and managing an atmosphere of the cavity with a dedicated hole, including making said cavity between a support and a cap layer such that a sacrificial material and the device are arranged in the cavity; removing the sacrificial material through at least one release hole, and hermetically sealing the release hole; making a portion of wettable material on the cap layer, around a blind hole or a part of said outside surface corresponding to a location of said dedicated hole; making a portion of fuse material on the portion of wettable material; making the dedicated hole by etching the cap layer; and reflowing the portion of fuse material with a controlled atmosphere, forming a bump of fuse material which hermetically plugs said dedicated hole.

  • Method of hermetically sealing a hole with a fuse material
    Patent number: 9199839
    Abstract: Method of hermetically sealing a hole with a fuse material, comprising the following steps: applying a portion of wettable material onto a surface such that it completely surrounds the hole made through said surface and is located outside the hole, or completely surrounds a first part of said surface corresponding to a location of the hole; applying a portion of fuse material on the portion of wettable material and on a second part of said surface located around the portion of wettable material; reflowing the portion of fuse material to form a bump of fuse material which has a shape corresponding to a part of a sphere, which is fastened only to the portion of wettable material and which hermetically plugs the hole; wherein the hole is made in said surface before reflowing the portion of fuse material.
