    摘要: In accordance with the present invention, an amorphous layer is formed in a crystalline substrate (e.g., the channel region of a MOSFET transistor) by, for example, implanting ions of an inert specie such as germanium. A dopant is implanted so that it overlaps with the amorphous layer. Subsequently, low temperature recrystallization of the amorphous layer leads to an abrupt retrograded layer of active dopant in the channel region of the MOSFET. This retrograded dopant layer could be formed before or after the formation of the gate electrode.

    摘要: A method for processing a semiconductor wafer transforms the wafer into one which has a plurality of surface semiconductor platforms for formation of integrated circuit elements thereupon. The platforms are connected to a subsurface bulk layer of semiconductor material via integrally-formed bridges of semiconductor material. The platforms are otherwise surrounded with an electrically-insulating material, thereby providing good insulation between adjacent of the platforms. The method includes the steps of placing a mask on a wafer surface of the wafer, forming a subsurface altered material beneath portions of the wafer surface not covered by the mask, creating exposure openings through the wafer surface to expose a portion of the subsurface altered material, selectively removing the subsurface altered material by selective etching, and filling the subsurface regions and the exposure openings with an electrically-insulating material. In an exemplary embodiment the mask includes a plurality of gate conductors. The wafer surface is bombarded with boron ions to create a subsurface boron-doped material, and the boron-doped material is removed using an appropriate selective etchant.
