Abstract
A semiconductor package includes a lead frame having a displaced integral strap which is cupped out of a lead frame plane to provide a nest that receives a semiconductor chip electrically connected to an inner surface of the cupped strap. The semiconductor package further has a housing molded over and encapsulating the semiconductor chip with the frame such that a surface of the semiconductor chip facing away from the cupped strip is flush with or protrudes beyond a bottom of the housing.
