Raised source/drain structure for enhanced strain coupling from stress liner
摘要:
A transistor is provided that includes a buried oxide layer above a substrate. A silicon layer is above the buried oxide layer. A gate stack is on the silicon layer, the gate stack including a high-k oxide layer on the silicon layer and a metal gate on the high-k oxide layer. A nitride liner is adjacent to the gate stack. An oxide liner is adjacent to the nitride liner. A set of faceted raised source/drain regions having a part including a portion of the silicon layer. The set of faceted raised source/drain regions also include a first faceted side portion and a second faceted side portion.
