    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.

    摘要: In one aspect, the present invention teaches a multiple-gate transistor 130 that includes a semiconductor fin 134 formed in a portion of a bulk semiconductor substrate 132. A gate dielectric 144 overlies a portion of the semiconductor fin 134 and a gate electrode 146 overlies the gate dielectric 144. A source region 138 and a drain region 140 are formed in the semiconductor fin 134 oppositely adjacent the gate electrode 144. In the preferred embodiment, the bottom surface 150 of the gate electrode 146 is lower than either the source-substrate junction 154 or the drain-substrate junction 152.

A first portion of the semiconductor layer has a first thickness. A second portion of the semiconductor layer has a second thickness. The second thickness is larger than the first thickness. The first transistor has a first active region formed from the first portion of the semiconductor layer. The second transistor has a second active region formed from the second portion of the semiconductor layer. The first transistor may be a planar transistor and the second transistor may be a multiple-gate transistor, for example.
