    摘要: MOSFETs and methods for making MOSFETs with a recessed channel and abrupt junctions are disclosed. The method includes creating source and drain extensions while a dummy gate is in place. The source/drain extensions create a diffuse junction with the silicon substrate. The method continues by removing the dummy gate and etching a recess in the silicon substrate. The recess intersects at least a portion of the source and drain junction. Then a channel is formed by growing a silicon film to at least partially fill the recess. The channel has sharp junctions with the source and drains, while the unetched silicon remaining below the channel has diffuse junctions with the source and drain. Thus, a MOSFET with two junction regions, sharp and diffuse, in the same transistor can be created.

    摘要: Asymmetric FET devices, and a method for fabricating such asymmetric devices on a fin structure is disclosed. The fabrication method includes disposing over the fin a high-k dielectric layer followed by a threshold-modifying layer, performing an ion bombardment at a tilted angle which removes the threshold-modifying layer over one of the fin's side-surfaces. The completed FET devices will be asymmetric due to the threshold-modifying layer being present only in one of two devices on the side of the fin. In an alternate embodiment further asymmetries are introduced, again using tilted ion implantation, resulting in differing gate-conductor materials for the two FinFET devices on each side of the fin.
