    摘要: A method for making a SOI wafer with a strained silicon layer for increased electron and hole mobility is achieved. The method forms a porous silicon layer on a seed wafer. A H2 anneal is used to form a smooth surface on the porous silicon. A strain free (relaxed) epitaxial SixGe1-x layer is deposited and a bonding layer is formed. The seed wafer is then bonded to a handle wafer having an insulator on the surface. A spray etch is used to etch the porous Si layer resulting in a SOI handle wafer having portions of the porous Si layer on the relaxed SixGe1-x. The handle wafer is then annealed in H2 to convert the porous Si to a smooth strained Si layer on the relaxed SiGe layer of the SOI wafer.

    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 and activation of dopant impurities. After the gate electrode is patterned, dopant impurities are selectively introduced to the semiconductor fin to form source/drain regions.
