摘要:
In forming an electronic device, a semiconductor layer is pre-doped and a dopant distribution anneal is performed prior to gate definition. Alternatively, the gate is formed from a metal. Subsequently formed shallow sources and drains, therefore, are not affected by the gate annealing step.
摘要:
A semiconductor device and a method for fabricating a semiconductor device involve a semiconductor layer that includes a first material and a second material. The first and second materials can be silicon and germanium. A contact of the device has a portion proximal to the semiconductor layer and a portion distal to the semiconductor layer. The distal portion includes the first material and the second material. A metal layer formed adjacent to the relaxed semiconductor layer and adjacent to the distal portion of the contact is simultaneously reacted with the relaxed semiconductor layer and with the distal portion of the contact to provide metallic contact material.
摘要:
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.
