Abstract
A semiconductor device includes a first body having a first coefficient of thermal expansion (CTE) and a first surface, a third body having a third CTE and a third surface facing the first surface, and a fourth surface at an angle with respect to the third surface defining an edge of the third body, and a second body having a second CTE higher than the first and the third CTE, the second body contacting the first and the third surfaces. A post having a fourth CTE lower than the second CTE, transects the second body and contacts the edge.
