Publication number: 20040135210Abstract: A field effect transistor of the present invention is formed in a strain effect semiconductor layer, represented by a strain effect silicon layer, formed in an upper layer of a semiconductor substrate. A source/a drain of the field effect transistor are formed only in the strain effect silicon layer. The field effect transistor may be formed as an nMOS transistor, and a pMOS transistor may be formed in the strain effect silicon layer while being isolated from the nMOS transistor through an isolation region. A logic circuit can be formed of these transistors. Although when an nMOS transistor or a pMos transistor is employed in an application requiring a high performance at a low voltage, there occurs a current leak because the junction of a source/a drain is positioned in a silicon germanium layer having a low band gap or formed at an interface of silicon/silicon germanium, the field effect transistor of the present invention prevents occurrence of such a current leak.Type: ApplicationFiled: January 8, 2004Publication date: July 15, 2004Inventors: Takashi Noguchi, Mitsuo Soneda

Publication number: 20040135211Abstract: According to a semiconductor device of the present invention, a field oxide film is formed so as to cover the main surface of an SOI layer and to reach the main surface of a buried oxide film.

Publication number: 20040135212Abstract: A MOSFET fabrication methodology and device structure, exhibiting improved gate activation characteristics. The gate doping that may be introduced while the source drain regions are protected by a damascene mandrel to allow for a very high doping in the gate conductors, without excessively forming deep source/drain diffusions. The high gate conductor doping minimizes the effects of electrical depletion of carriers in the gate conductor. The MOSFET fabrication methodology and device structure further results in a device having a lower gate conductor width less than the minimum lithographic minimum image, and a wider upper gate conductor portion width which may be greater than the minimum lithographic image. Since the effective channel length of the MOSFET is defined by the length of the lower gate portion, and the line resistance is determined by the width of the upper gate portion, both short channel performance and low gate resistance are satisfied simultaneously.Type: ApplicationFiled: January 14, 2003Publication date: July 15, 2004Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Omer H.
