摘要: FinFET devices are formed with body contact structures enabling the fabrication of such devices having different gate threshold voltages (Vt). A body contact layer is formed to contact the gate electrode (contact) enabling a forward body bias and a reduction in Vt. Two example methods of fabrication (and resulting structures) are provided. In one method, the gate electrode (silicon-based) and body contact layer (silicon) are connected by growing epitaxy which merges the two structures forming electrical contact. In another method, a via is formed that intersects with the gate electrode (suitable conductive material) and body contact layer and is filled with conductive material to electrically connect the two structures. As a result, various FinFETs with different Vt can be fabricated for different applications.

摘要: A method (and semiconductor device) of fabricating a semiconductor device adjusts gate threshold (Vt) of a field effect transistor (FET) with raised source/drain (S/D) regions. A halo region is formed in a two-step process that includes implanting dopants using conventional implantation techniques and implanting dopants at a specific twist angle. The dopant concentration in the halo region near the active edge of the raised S/D regions is higher and extends deeper than the dopant concentration within the interior region of the raised S/D regions. As a result, Vt near the active edge region is adjusted and different from the Vt at the active center regions, thereby achieving same or similar Vt for a FET with different width.
