Abstract

A semiconductor baseplate is disclosed. Specific implementations of a baseplate may include a planar portion including a plurality of recesses therein, the planar portion may be made of a first material, and a plurality of pegs where each peg of the plurality of pegs may be configured to fit within each recess of the plurality of recesses, the plurality of pegs may be made of a second material, where the first material and the second material may be bonded together.

Claims (29)

1. A baseplate comprising:

a planar portion comprising a plurality of recesses therein, the planar portion further comprising a first material; and

a plurality of pegs wherein each peg of the plurality of pegs is configured to fit within each recess of the plurality of recesses, the plurality of pegs further comprising a second material;

wherein the first material and the second material are bonded together; and

wherein each peg of the plurality of pegs is configured to directly contact a bonding material, the bonding material configured to couple to a substrate.

2. The baseplate of claim 1 , wherein each recess of the plurality of recesses in its the planar portion is a recess therethrough.

3. The baseplate of claim 1 , wherein each recess of the plurality of recesses forms a closed shape.

4. The baseplate of claim 3 , wherein each recess of the plurality of recesses forms a hexagonal shape.

5. The baseplate of claim 3 , wherein each recess of the plurality of recesses forms a circular shape.

6. The baseplate of claim 1 , wherein each of the plurality of pegs comprise a plug.

7. The baseplate of claim 1 , wherein each of the plurality of pegs comprise a pin.

8. The baseplate of claim 1 , wherein the planar portion further comprises at least one screw hole therethrough.

9. The baseplate of claim 1 , wherein the first material comprises a metal with a coefficient of linear thermal expansion close to a substrate material to which the planar portion is configured to be coupled to.

10. The baseplate of claim 1 , wherein the second material comprises a material that is more thermally conductive than the first material.

11. A baseplate comprising:

a planar portion comprising a plurality of recesses therethrough, the planar portion further comprising a first material; and

a plurality of pegs wherein each peg of the plurality of pegs is configured to fit within each recess of the plurality of recesses, the plurality of pegs further comprising a second material;

wherein the first material and the second material are bonded together; and

wherein each peg of the plurality of pegs is configured to directly contact a bonding material, the bonding material configured to couple to a substrate.

12. The baseplate of claim 11 , wherein each recess of the plurality of recesses forms a closed shape.

13. The baseplate of claim 11 , wherein the planar portion further comprises at least one screw hole therethrough.

14. The baseplate of claim 11 , wherein the first material comprises a metal with a coefficient of linear thermal expansion close to a substrate material to which the planar portion is configured to be coupled to.

15. The baseplate of claim 11 , wherein the second material comprises a material that is more thermally conductive than the first material.

16. A baseplate comprising:

a planar portion comprising a plurality of recesses therein, the planar portion further comprising a first material; and

a plurality of pegs wherein each peg of the plurality of pegs is configured to fit within each recess of the plurality of recesses, the plurality of pegs further comprising a second material;

wherein each peg of the plurality of pegs is configured to directly contact a bonding material, the bonding material configured to couple to a substrate.

17. The baseplate of claim 16 , wherein the first material and the second material are bonded together.

18. The baseplate of claim 16 , wherein the first material comprises a metal with a coefficient of linear thermal expansion close to a substrate material to which the planar portion is configured to be coupled to, and the second material comprises a material that is more thermally conductive than the first material.
