Patent ID: 8338236

Claim:
A method of packaging a semiconductor device, comprising: providing a substrate having a die attach pad surrounded by a plurality of substrate wire bond pads, and a vent forming a hole from a first side of the substrate to a second side of the substrate, wherein the vent is located between the die attach pad and at least one of the wire bond pads; placing a semiconductor die on the die attach pad on the first side of the substrate; electrically connecting the die with the wire bond pads with wires using a wire bonding process; clamping a first mold form to the first side of the substrate to form a mold cavity between the first mold form and the first side of the substrate with the semiconductor die; injecting a mold compound into the mold cavity by way of an injection port in the first mold form, wherein the mold compound and gas within the mold cavity exit the mold cavity by way of the vent in the substrate; and removing the first mold form piece from the substrate, thereby forming a packaged semiconductor device, the mold compound covers the die and the wires, and fills the vent.
