Abstract:
A method and a package for circuit chip package having a bent structure. The circuit chip package includes: a substrate having a first coefficient of thermal expansion (CTE); a circuit chip, having a second CTE, mounted onto the substrate; a metal foil disposed on the circuit chip in thermal contact with the chip; a metal lid having (i) a third CTE that is different from the first CTE and (ii) a bottom edge region, where the metal lid is disposed on the metal foil in thermal contact with the metal foil; and an adhesive layer along the bottom edge of the metal lid, cured at a first temperature, bonding the lid to the substrate, producing an assembly which, at a second temperature, is transformed to a bent circuit chip package.
