摘要: First and second fins are formed extending from a substrate. A first layer is formed over the first fin. The first layer comprises a first dopant. A portion of the first layer is removed from a tip portion of the first fin. A second layer is formed over the second fin. The second layer comprises a second dopant. One of the first and second dopants is a p-type dopant, and the other of the first and second dopants is an n-type dopant. A portion of the second layer is removed from a tip portion of the second fin. A solid phase diffusion process is performed to diffuse the first dopant into a non-tip portion of the first fin, and to diffuse the second dopant into a non-tip portion of the second fin.

摘要: A system and method for manufacturing multiple-gate semiconductor devices is disclosed. An embodiment comprises multiple fins, wherein intra-fin isolation regions extend into the substrate less than inter-fin isolation regions. Regions of the multiple fins not covered by the gate stack are removed and source/drain regions are formed from the substrate so as to avoid the formation of voids between the fins in the source/drain region.
