Abstract

See full text

A semiconductor device includes a work piece comprising a first material, a first side, a second side opposite to the first side, and a first coefficient of thermal expansion (first CTE). Recesses extend into the work piece from the first side and includes a pattern. A second material having a second CTE is within the recesses and is over the first material between the recesses; and A third material having a third CTE is over one of the second side or the second material. The third CTE and the second CTE are different than the first CTE.
