Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device wherein a leak current increase due to miniaturization is controlled and an excellent channel mobility is available, and to provide a method for manufacturing the same.  <P>SOLUTION: A gate insulating film containing Hf, Al, O, and N is formed on a semiconductor substrate. The gate insulating film is a mixture for instance of an HfO<SB>2</SB>film and an Al<SB>2</SB>O<SB>3</SB>film, and is formed by an MOCVD method for example or the like. In this method, immediately after the start of film formation, the Al<SB>2</SB>O<SB>3</SB>film material is supplied more than the HfO<SB>2</SB>film material so that the ratio of the Al<SB>2</SB>O<SB>3</SB>film formation rate to the HfO<SB>2</SB>film formation rate is approximately 3:7. Then, as time passes, the supply of the Al<SB>2</SB>O<SB>3</SB>film material is decreased and the supply of the HfO<SB>2</SB>film material is increased. Immediately before the end of film formation, the supply of the Al<SB>2</SB>O<SB>3</SB>film material is stopped, and only the HFO<SB>2</SB>film material is supplied. The result is that the Al content increases from the topmost surface of the film toward the boundary of the film with the semiconductor substrate.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-04-02
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the power generating efficiency of the solar battery modules from falling by removing the rain water on the light receiving surfaces of the modules at the time of laying many modules on ties by utilizing the track surface of a railway.  <P>SOLUTION: A structure is constructed to make solar power generation by laying many solar battery modules 1. Each of the modules is formed in a panel body by backing a sheet-like solar battery having both surfaces sealed with a protective material with a reinforcing plate 4, on the track plane inside rails 10a along the track 10 of the railway line. The modules 1 are formed so that the whole bodies of the modules 1 may become gentle crest-like forms by crest-folding (crest-folding lines: P) the reinforcing plates 4 at their centers. Consequently, the falls of the power generating efficiency of the solar battery modules 1 caused by rain water staying on the light receiving surfaces of the modules 1 can be prevented, because the rain water falling onto the light receiving surfaces quickly flows down along the surfaces and, accordingly, the water is quickly discharged from the surfaces.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
