MASK PATTERN DESIGN DEVICE AND MASK PATTERN DESIGN INFORMATION DISPLAY METHOD

摘要

PURPOSE:To lighten the load on a designer by selecting arrangement relation image data indicating that a specified element and other elements are in specific arrangement relation and displaying an image based upon the image data. CONSTITUTION:When a command for displaying a circuit diagram image is inputted with a mouse 17, circuit information on a storage device 20 is transferred to a processor 18 and circuit diagram image data are generated. An elliptic figure 9 for arranging transistors(TR) 6 and 7 closely together with resistances 4 and 5 and TRs 6-8 is displayed as a circuit diagram image in a window 2 on a graphic display 15 according to the image data. Then an operator specifies an optional element among elements displayed in the window 2 and inputs a pattern generation command and the mask pattern of the specified element is displayed as an image in a window 3. Consequently, the layout of a mask pattern is made without referring to the circuit diagram and the load on the designer is lightened.
