Package structure and method of forming thereof

Abstract

A method of forming a package structure includes disposing a die adhesive layer on a wafer, lowering a partial connecting property of the die adhesive layer, separating a plurality of dies of the wafer and disposing each of the dies on a leadframe. A connecting property of a partial area of the die adhesive layer is lowered, and the connecting property of the partial area of the die adhesive layer is corresponding to a plurality of cutting streets of the wafer. The dies are separated according to the cutting streets of the wafer. The partial area of the die adhesive layer is corresponding to a plurality of leads of the leadframe, and a connecting strength between the die adhesive layer and each of the leads is lower than a connecting strength between the die adhesive layer and a die pad of the leadframe.

Dependencies are inferred from the claim text.
