ABSTRACT:
A package for a semiconductor die includes a die attach pad that provides an attachment surface area for the semiconductor die, and tie bars connected to the die attach pad. The die attach pad is disposed in a first general plane and the tie bars are disposed in a second general plane offset with respect to the first general plane. A molding compound encapsulates the semiconductor die in a form having first, second, third and fourth lateral sides, a top and a bottom. The tie bars are exposed substantially coincident with at least one of the lateral sides. The form includes a discontinuity that extends along the at least one of the lateral sides, the discontinuity increasing a creepage distance measured from the tie bars to the bottom of the package.
