Abstract:
A method is for making a semiconductor device. The method may include providing a lead frame having a recess, forming a sacrificial material in the recess of the lead frame, and mounting an IC on the lead frame. The method may include encapsulating the IC and the lead frame, removing portions of the lead frame to define lead frame contacts for the IC, and removing the sacrificial material to define for each lead frame contact a solder anchoring tab extending outwardly at a lower region and defining a sidewall recess between opposing portions of the solder anchoring tab and the encapsulation material.
