Abstract:
A dislocation filter for a semiconductor device has a buffer layer comprising a short-period superlattice (SPSL) layer. The SPSL layer has first sub-layers of a first material that alternate with second sub-layers of a second material, the first material and the second material being group III-N binary materials that are different from each other. Each of the first sub-layers and each of the second sub-layers has a sub-layer thickness less than or equal to 12 monolayers. The buffer layer also includes a third layer of a third material, the third material being a group III-N material. The SPSL forms a sandwich structure with the third layer. The buffer layer bends dislocations away from a growth direction of the buffer layer.

Claim (Index 10):
The device of  claim 8 , wherein a monolayer ratio of the GaN sub-layers to the AlN sub-layers in the SPSL layer is 1:4.
