A semiconductor structure includes of a plurality of semiconductor fins overlying an insulator layer, a gate dielectric overlying a portion of said semiconductor fin, and a gate electrode overlying the gate dielectric. Each of the semiconductor fins has a top surface, a first sidewall surface, and a second sidewall surface. Dopant ions are implanted at a first angle (e.g., greater than about 7°) with respect to the normal of the top surface of the semiconductor fin to dope the first sidewall surface and the top surface. Further dopant ions are implanted with respect to the normal of the top surface of the semiconductor fin to dope the second sidewall surface and the top surface.

摘要:
A method for forming a gate electrode for a multiple gate transistor provides a doped, planarized gate electrode material which may be patterned using conventional methods to produce a gate electrode that straddles the active area of the multiple gate transistor and has a constant transistor gate length. The method includes forming a layer of gate electrode material having a non-planar top surface, over a semiconductor fin. The method further includes planarizing and doping the gate electrode material, without doping the source/drain active areas, then patterning the gate electrode material. Planarization of the gate electrode material may take place prior to the introduction and activation of dopant impurities or it may follow the introduction arid activation of dopant impurities. After the gate electrode is patterned, dopant impurities are selectively introduced to the semiconductor fin to form source/drain regions.

In accordance with a preferred embodiment of the present invention, a silicon-on-insulator (SOI) chip includes a silicon layer of a predetermined thickness overlying an insulator layer. A multiple-gate fully-depleted SOI MOSFET including a strained channel region is formed on a first portion of the silicon layer. A planar SOI MOSFET including a strained channel region formed on another portion of the silicon layer. For example, the planar SOI MOSFET can be a planar fully-depleted SOI (FD-SOI) MOSFET or the planar SOI MOSFET can be a planar partially-depleted SOI (PD-SOI) MOSFET.
