Abstract

Implementations of methods of forming a plurality of reinforced die may include forming a plurality of die on a substrate and patterning a metal gang frame to form a plurality of metal plates. The plurality of metal plates may correspond to the plurality of die. The method may include coupling the metal gang frame over the plurality of die and singulating the plurality of die. Each die of the plurality of die may include the corresponding metal plate from the plurality of metal plates coupled over the plurality of die.

Claims (31)

1. A reinforced semiconductor die comprising:

a substrate comprising a die; and

a metal plate coupled over the substrate, the metal plate comprising a plurality of tie bars extending from a plurality of sides of the metal plate;

wherein the die is configured to be electrically coupled to a wire through the metal plate.

2. The reinforced semiconductor die of claim 1 , wherein each tie bar extends to an outer perimeter of the substrate.

3. The reinforced semiconductor die of claim 1 , further comprising a base plate coupled to a second side of the substrate, wherein the second side of the substrate is opposite a first side of the substrate facing the metal plate.

4. The reinforced semiconductor die of claim 1 , wherein the substrate comprises a plurality of die.

5. The reinforced semiconductor die of claim 1 , wherein the substrate is less than 75 microns thick.

6. The reinforced semiconductor die of claim 1 , wherein the die comprises a power semiconductor device.

7. The reinforced semiconductor die of claim 1 , wherein the reinforced semiconductor die is singulated.

8. A reinforced semiconductor die comprising:

a substrate comprising a die; and

a conductive plate directly coupled to a first side of the substrate through an adhesive;

a base plate coupled to a second side of the substrate, the second side opposite the first side;

wherein the conductive plate comprises a tie bar extending from each of four sides of the conductive plate.

9. The reinforced semiconductor die of claim 8 , wherein the die is configured to be electrically coupled to a wire through the conductive plate.

10. The reinforced semiconductor die of claim 8 , wherein each tie bar terminates at an outer perimeter of the substrate.
