Abstract

A stiffened semiconductor die package has a semiconductor die including an integrated circuit. The die has an active side with die bonding pads and an opposite inactive side. A conductive frame that acts as a ground plane surrounds all edges of the die and a mold compound covers the conductive frame and the edges of the die. A thermally conductive sheet is attached to the inactive side of the die. A dielectric support structure with external connector pads with solder deposits is attached to the active side of the die. The external connector pads are selectively electrically coupled to the die bonding pads.

Claims (14)

1. A stiffened semiconductor die package, comprising:

a semiconductor die including an integrated circuit, the semiconductor die having an active side with die bonding pads and an opposite inactive side;

a conductive frame surrounding edges of the semiconductor die, wherein the conductive frame acts as a ground plane;

a mold compound that covers the conductive frame and the semiconductor die;

a thermally conductive sheet attached to the inactive side of the semiconductor die; and

a dielectric support structure with external connector pads having solder deposits mounted thereto, the dielectric support structure being attached to the active side of the semiconductor die and wherein the external connector pads are electrically coupled to respective ones of the die bonding pads.

2. The stiffened semiconductor die package of claim 1 , wherein at least one of the external connector pads is also electrically coupled to the conductive frame.

3. The stiffened semiconductor die package of claim 1 , wherein a surface of the conductive frame is coplanar with a surface of the die bonding pads.

4. The stiffened semiconductor die package of claim 3 , wherein the inactive side of the semiconductor die is coplanar with an aligned surface of the mold compound.

5. The stiffened semiconductor die package of claim 4 , wherein the thermally conductive sheet is also attached to the aligned surface of the mold compound.

6. The stiffened semiconductor die package of claim 5 , wherein the mold compound forms a rectangular frame around the edges of the semiconductor die.

7. The stiffened semiconductor die package of claim 6 , wherein the mold compound is molded to the edges of the semiconductor die.

8. The stiffened semiconductor die package of claim 1 , wherein the solder deposits form a grid array structure.

9. The stiffened semiconductor die package of claim 1 , wherein the dielectric support structure is attached to the conductive frame thereby sandwiching conductive frame and mold compound between the thermally conductive sheet and the dielectric support structure.
