IPC: G06T11/60
Filed: 1988-02-19
Abstract: PURPOSE:To quickly and accurately correct a drawing of facility by extracting automatically an unmatched symbol which cannot be connected to a changed graphic in case the data hierarchical change is applied to a graphic where the graphic and symbol of the drawing of facility are connected to each other. CONSTITUTION:A target facility drawing is retrieved out of a file device 203 and the drawing data is edited and displayed on a CRT 205. In case a partial graphic of the displayed drawing is changed into another graphic, i.e., the data hierarchy is changed, the data hierarchy to which the facility symbols belong is collated with the data hierarchy of the corresponding facility flow sheet to check the connecting definition to the corresponding symbol and the unmatched symbols are automatically extracted. Therefore an unmatched state can be decided between the symbol of the facility drawing and its corresponding facility system in case the data hierarchy of the facility flow sheet is changed. In such a way, the drawing can be quickly and accurately corrected.

IPC: H01L21/3205
Filed: 1988-02-17
Abstract: PURPOSE:To eliminate the effect of steps on a metal wiring and to make it possible to prevent the breakdown and the short circuit of the metal wiring, by selectively oxidizing a semiconductor substrate in region where polysilicon layers are formed on a field oxide film, removing all the oxide film, and thereafter forming a field oxide film. CONSTITUTION:In regions 11 where polysilicon layers 6b are formed on a field oxide film 5, recess parts are formed in a semiconductor substrate 1 before the field oxide film is formed. When the field oxide film 5 is formed, recess parts 12 are formed in the regions where the polysilicon layers 6b are formed on the field oxide film. When the polysilicon layers 6b are formed, the polysilicon layers are formed in the recess parts 12 of the field oxide film. Thus, steps on the field oxide film 5 are made small. The effect of the steps due to the thicknesses of the polysilicon wirings 6b does not appear on the surface of an interlayer insulating film 7 that is formed on the layer 5. Therefore, the effect of the steps does not appear on a metal wiring 8 on the interlayer insulating film 7.
