Abstract:
PROBLEM TO BE SOLVED: To provide an easy method for forming a compact pad whose manufacturing cost can be reduced. SOLUTION: A region 51 is an area 510 that extends at least up to part of the front surface of the region, and can be locally changed for the purpose of forming the area using a material that can be selectively removed from the region. This region is covered with an insulating material 7, and an orifice 90 that appears on the front surface of the area 510 is formed in the insulating material. The material that can be selectively removed is removed from this area through the orifice so that a cavity 520 may be formed in place of this area. The cavity and the orifice are filled up with at least one conductive material 91. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
A region of monocrystalline silicon (20, 124 - 128) on insulator on silicon (24, 120) is destined to receive at least one component. The insulator (26) comprises some over-thickness (OT).

Abstract:
The fabrication of a MOS transistor comprises the production of extension source and drain regions incorporating the formation of a gate region on a semiconductor substrate and an implantation of doping agents either side and at a distance from the gate. The production of extension source and drain regions includes the formation of an intermediate layer (CI) on the sides of the gate (GR) and on the surface of the substrate. The intermediate layer is formed of a material less dense than silicon dioxide and the implantation of doping agents (IMP) is effected across the part of the intermediate layer situated on the substrate. An Independent claim is also included for an integrated circuit incorporating at least one transistor fabricated by this method.

Abstract:
Fabrication of an integrated circuit, incorporating a crystalline silicon substrate and a gate formed on the substrate, consists of: (a) treating a region of the substrate to obtain an amorphous silicon region; (b) implanting a doping species into a sub-region included in the region of the substrate to form some extensions of the drain and source; (c) forming of the drain and source at low temperature. An Independent claim is also included for an integrated circuit incorporating at least one transistor obtained by this method. The temperature used in the drain and source formation stage is less than 800 degrees C.
