Abstract

A semiconductor assembly includes a semiconductor die comprising lower and upper electrical contacts. A lead frame having a lower die pad is electrically and mechanically connected to the lower electrical contact of the die. An upper conductive member has a first portion electrically and mechanically connected to the upper electrical contact of the die. A lead terminal has a surface portion electrically and mechanically connected to a second portion of the conductive member. The surface portion of the lead terminal and/or the second portion of the conductive member has a series of grooves disposed therein. Packaging material encapsulates the semiconductor die, at least a portion of the lead frame, at least a portion of the upper conducive member and at least a portion of the lead terminal.
