    摘要: Disclosed are a method which improves the performance of a semiconductor element, and a semiconductor element with improved performance. The method for forming a semiconductor element structure includes a heterojunction forming step in which a heterojunction is formed between a strained semiconductor layer (21) in which a strained state is maintained, and relaxed semiconductor layers (23, 25). The heterojunction is formed by performing ion implantation from the surface of a substrate (50) which has a strained semiconductor layer (20) partially covered with a covering layer (30) on an insulating oxide film (40), and altering the strained semiconductor layer (20) where there is no shielding from the covering layer (30) to relaxed semiconductor layers (23, 25) by relaxing the strained state of the strained semiconductor layer (20), while maintaining the strained state of the strained semiconductor layer (21) where there is shielding from the covering layer (30).

    摘要: At the surface of a p-type silicon substrate, n-type source/drain diffused layers are formed. On the substrate between the source/drain diffused layers, a gate insulating film made of a silicon oxide film is formed so as to be isolated from the diffused layers. A gate electrode is formed on the gate insulating film. Sidewalls are formed on the sides of the gate insulating film and gate electrode, extending upward from the substrate. In this invention, the sidewalls are composed of material whose permittivity is higher than that of the gate insulating film, for example, of a silicon nitride film.

    摘要: A method of manufacturing a semiconductor device which includes forming a first SiGe layer having a low content of Ge, forming an oxide layer by implanting oxygen ions into the first SiGe layer, and then annealing the first SiGe layer. The method also includes forming, on the first SiGe layer, a second SiGe layer which has a higher content of Ge than the first SiGe layer, forming a strained Si layer on the second SiGe layer, and forming a field effect transistor in which the strained Si layer is used a channel region. Further, a field effect transistor may be formed on a semiconductor substrate having an indefectible, high-quality, buried oxide layer and a largely strained Si layer, and hence a high-speed, low-power-consumption semiconductor device can be realized.
