Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To identify and select the different grids according to the graphic forms, characters and attributes of unit of displaying and to improve the workability for setting positions of the graphic forms and characters by detecting whether or not the determination of a display position is instructed and then detecting whether unit of displaying of the display position shown by a cursor is equivalent to a graphic form or a character or not when the determination is instructed. SOLUTION: When it's confirmed that the determination is instructed for the position of every unit of displaying (S01), the attribute of unit of displaying is decided for the position of a cursor (S02). When a control program decides that unit of displaying shown by the cursor has a graphic attribute, a rough graphic grid mesh, for example, is selected (S06). Thereafter, it's detected in the same way whether unit of displaying has a wiring attribute (S03) or not. If unit of displaying has no wiring attribute, it's decided that unit of displaying is a character attribute and a character grid mesh is selected (S04). Then it's decided whether or not the characters can be arranged in the character grid mesh (S07). If the mesh is too rough, a finer grid mesh is selected (S08).

Title: Method for cleaning silicon wafer
Inventor: IWAMOTO YOSHIO
IPC: H01L21/304
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To improve withstand voltage characteristics of an oxide film on the surface of a silicon wafer and to improve the degree of cleanness of the surface of the silicon wafer at the same time by cleaning the silicon wafer with a mixed liquid of HF-H2 O2 -H2 O having a volumetric ratio of HF:H2 O2 :H2 O in a specified range. SOLUTION: A silicon wafer is cleaned with a mixed liquid of HF-H2 O2 -H2 O having a volumetric ratio of HF:H2 O2 :H2 O=1:1:50 to 1:10:50 at a temperature of 10 to 60 deg.C. When an oxide film on the silicon wafer is removed by HF etching, impurities of transition metals are removed from the surface of the silicon wafer and are prevented from sticking to the surface again by making the composition of H2 O2 equal to that of HF. This can improve withstand voltage characteristics of the oxide film. Also, since an oxidative action is increased by increasing the composition of H2 O2 to ten times that of HF, it can improve the degree of cleanness of the surface of the silicon wafer.
