Abstract
The present disclosure relates to a hermetic package capable of handling a high coefficient of thermal expansion (CTE) mismatch configuration. The disclosed hermetic package includes a metal base and multiple segments that are discrete from each other. Herein, a gap exists between every two adjacent ceramic wall segments and is sealed with a connecting material. The ceramic wall segments with the connecting material form a ring wall, where the gap between every two adjacent ceramic wall segments is located at a corner of the ring wall. The metal base is either surrounded by the ring wall or underneath the ring wall.
Claims20
A package comprising:
- a metal base having a top surface;
- and
- multiple ceramic wall segments discrete from each other, wherein:
- a gap exists between every two adjacent ceramic wall segments and is sealed with a connecting material;
- the ceramic wall segments with the connecting material form a ring wall, wherein the gap between every two adjacent ceramic wall segments is located at a corner of the ring wall;
- and
- the ring wall is attached to the top surface of the metal base, such that a portion of the top surface of the metal base is exposed through the ring wall.
