Title: Surface treating method of silicon carbide
Inventor: TASAKA AKIMASA
IPC: C04B41/80
Filed: 2007-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a surface treating method of silicon carbide, in which the surface of silicon carbide is subjected to microfabrication into an optional shape and with high accuracy, especially microfabrication with the dimensional tolerance of nanometer level when the surface of the silicon carbide is subjected to microfabrication by reactive ion etching.  <P>SOLUTION: The surface treating method is performed before subjecting the surface of a single crystal silicon carbide substrate to microfabrication by reactive ion etching (RIE). In the method, the surface of the single crystal silicon carbide substrate is subjected to chemical cleaning sequentially using one or more selected from the group comprising an aqueous solution containing ammonia and hydrogen peroxide, an aqueous solution containing hydrochloric acid and hydrogen peroxide, an aqueous solution containing sulfuric acid and hydrogen peroxide, and an aqueous solution containing hydrofluoric acid and hydrogen peroxide and then, the surface is subjected to an oxygen plasma treatment.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Filed: 2007-05-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a technique capable of surely acquiring the image of the part under consideration of a fundus compared to a conventional case.  <P>SOLUTION: The fundus observation apparatus 1 can form the near infrared moving image and color image (still image) of the fundus Ef. The fundus observation apparatus 1 specifies an image area in the near infrared moving image corresponding to the area under consideration in the color image when the near infrared moving image is formed. Further, the fundus observation apparatus 1 forms a tomographic image along the scanning line by scanning signal light LS on the basis of the specified image area. Also, the area under consideration means the image area corresponding to the part under consideration of the fundus Ef. By the fundus observation apparatus 1, since the area under consideration in the still image of relatively high image quality is determined, the image area in the moving image corresponding to the area under consideration is specified and the measurement part of the tomographic image is set, the image of the part under consideration of the fundus Ef is surely acquired compared to the conventional method of setting the measurement part by referring only to the moving image of relatively low image quality.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Method of manufacturing semiconductor device
Inventor: OKI SHUHEI
IPC: H01L29/78
Filed: 2007-05-23
Abstract: <P>PROBLEM TO BE SOLVED: To manufacture a semiconductor device without leaving a deep recess on the surface of a polysilicon layer for trench filling.  <P>SOLUTION: Trenches 50 are formed on a semiconductor substrate 10. An oxide film 12 is formed on the surface of the semiconductor substrate 10 including inner walls of the trenches 50. A polysilicon layer 18 is formed so as to fill the trenches 50. At this time, a recess 52 is formed at the opening of each trench 50. Electrically inactive ions are implanted into the polysilicon layer 18 to amorphize a surface layer 20. The amorphous polysilicon layer 18 formed on the surface layer 20 is thermally oxidized. Since the polysilicon surface layer 20 is amorphized, the thermal oxidization causes planarization upon the oxidization. Thus, even when the polysilicon layer 18 other than the interiors of the trenches 50 is removed, no deep recesses are left on the surface of the polysilicon at the openings of the trenches 50. Consequently, there can be manufactured a semiconductor device which has no deep recesses on the surface of the polysilicon layer filling the trenches 50.  <P>COPYRIGHT: (C)2009,JPO&INPIT
