Abstract

Implementations of a semiconductor package may include one or more semiconductor die directly coupled to only a direct leadframe attach (DLA) leadframe including two or more leads; and a coating covering the one or more semiconductor die and the DLA leadframe where when the semiconductor package is coupled into an immersion cooling enclosure, the coating may be in contact with a dielectric coolant while the two or more leads extend out of the immersion cooling enclosure.

Claims (24)

1. A semiconductor package comprising:

one or more semiconductor die directly coupled to only a direct leadframe attach (DLA) leadframe comprising two or more leads; and

a coating covering the one or more semiconductor die and the DLA leadframe;

wherein when the semiconductor package is coupled into an immersion cooling enclosure, the coating is in contact with a dielectric coolant while the two or more leads extend out of the immersion cooling enclosure.

2. The package of claim 1 , wherein mold compound is molded around the two or more leads and the mold compound forms a seal for the dielectric coolant.

3. The package of claim 1 , further comprising a heat spreader coupled to the one or more semiconductor die.

4. The package of claim 3 , wherein the heat spreader comprises pin fins.

5. The package of claim 1 , wherein the one or more semiconductor die are comprised in a die module coupled directly to the DLA leadframe.

6. The package of claim 1 , wherein one or more of the two or more leads comprise a spring.

7. The package of claim 6 , wherein the spring is comprised in mold compound molded around the two or more leads.

8. The package of claim 6 , wherein the spring is located adjacent to the one or more semiconductor die.

9. A semiconductor package comprising:

two or more semiconductor modules, each semiconductor module comprising:

one or more semiconductor die directly coupled to only a direct leadframe attach (DLA) leadframe comprising two or more leads;

a coating covering the one or more semiconductor die and the DLA leadframe; and

mold compound molded around the two or more leads of each of the two or more semiconductor modules;

wherein when the two or more semiconductor modules are coupled into an immersion cooling enclosure, the coating is in contact with a dielectric coolant while the two or more leads of each of the two or more semiconductor module extend out of the immersion cooling enclosure.

10. The package of claim 9 , wherein the mold compound forms a seal for the dielectric coolant.

11. The package of claim 9 , further comprising a heat spreader coupled to the one or more semiconductor die.

12. The package of claim 11 , wherein the heat spreader comprises pin fins.

13. The package of claim 9 , wherein the one or more semiconductor die are comprised in a die module coupled directly to the DLA leadframe.

14. The package of claim 9 , wherein one or more of the two or more leads comprise a spring.

15. The package of claim 14 , wherein the spring is comprised in mold compound molded around the two or more leads.

16. The package of claim 14 , wherein the spring is located adjacent to the one or more semiconductor die.
