摘要： In a semiconductor substrate in a first section, a channel region having an impurity concentration peak in an interior of the semiconductor substrate is formed, and in the semiconductor substrate in a second section and a third section, channel regions having an impurity concentration peak at a position close to a surface of the substrate are formed. Then, extension regions are formed in the first section, the second section and the third section. After that, the substrate is thermally treated to eliminate defects produced in the extension regions. Then, using gate electrodes and side-wall spacers as a mask, source/drain regions are formed in the first section, the second section and the third section.

摘要： A semiconductor device includes a first, second, and third MIS transistors of a first conductivity type respectively including a first, second, and third gate electrodes on a first, second, and third active regions of a semiconductor substrate with a first, second, and third gate insulating films interposed therebetween. The first gate insulating film is formed of a first silicon oxide film and a first high-k insulating film on the first silicon oxide film. The second gate insulating film is formed of a second silicon oxide film and a second high-k insulating film on the second silicon oxide film. The third gate insulating film is formed of a third silicon oxide film and a third high-k insulating film on the third silicon oxide film. The second silicon oxide film has a same thickness as the first silicon oxide film, and a greater thickness than the third silicon oxide film.

摘要： A semiconductor device includes a first-conductivity-type first MIS transistor and a second-conductivity-type second MIS transistor. The first and second MIS transistors include a first and a second gate insulating film formed on a first and a second active region surrounded by a separation region of a semiconductor substrate, and a first and a second gate electrode formed on the first and second gate insulating films. The first and second gate insulating films are separated from each other on a first separation region of the separation region. A distance s between first ends of the first and second active regions facing each other with the first separation region being interposed therebetween, and a protrusion amount d1 from the first end of the first active region to a first end of the first gate insulating film located on the first separation region establish a relationship d1
