  • Semiconductor heterostructures having reduced dislocation pile-ups and related methods
    Patent number: 7829442
    Abstract: Dislocation pile-ups in compositionally graded semiconductor layers are reduced or eliminated, thereby leading to increased semiconductor device yield and manufacturability. This is accomplished by introducing a semiconductor layer having a plurality of threading dislocations distributed substantially uniformly across its surface as a starting layer and/or at least one intermediate layer during growth and relaxation of the compositionally graded layer. The semiconductor layer may include a seed layer disposed proximal to the surface of the semiconductor layer and having the threading dislocations uniformly distributed therein.
