Abstract: A semiconductor device includes a MISFET. The semiconductor device also includes a silicon nitride film 12 and a silicon nitride film 10 arranged on the silicon nitride film 12. The silicon nitride film 12 covers at least a portion of an upper part of a source/drain 8 of the MISFET and has a film thickness thinner than a height of a gate electrode 4. The source/drain 8 includes nickel silicide 9 on its boundary to the silicon nitride film 10. The silicon nitride film 10 is a stressed film. A tight adhering property between the silicon nitride film 12 and the surface of the source/drain 8 and that between the silicon nitride film 12 and the silicon nitride film 10 are rendered higher than a tight adhering property which would prevail when the silicon nitride film 10 be made to adhere tightly to the source/drain 8.

Abstract: A method of manufacturing N-type MOSFET includes: implanting a p-type dopant into in a surface layer of a semiconductor substrate to form a channel region; forming a gate insulating film including High-k material and a gate electrode on said channel region; implanting a p-type dopant into both ends of said channel region in an inner portion of said semiconductor substrate to form halo regions; implanting a p-type dopant into both ends of said channel region in a surface layer of said semiconductor substrate to form extension regions. One of said step of forming said channel region and said step of forming halo regions includes: implanting C into one of said channel region and said halo regions. An inclusion amount of said High-k material is an amount that increase of a threshold voltage caused by said High-k material being included in said gate insulating film compensates for decrease of said threshold voltage caused by said C being implanted.

Abstract: In a silicon-on-insulator (SOI)-type semiconductor device, a buried silicon dioxide layer is produced in the silicon substrate. An area of the silicon substrate, which is sited above the buried silicon dioxide layer, is defined as an SOI area, and the remaining area is defined as a non-SOI area. A peripheral edge portion of the buried silicon dioxide layer is formed as a swelling edge portion. A first field-isolation layer is formed at the SOI area along the swelling edge portion of the buried silicon dioxide layer, a second field-isolation layer is formed at the non-SOI area along the swelling edge portion of the buried silicon dioxide layer.
