Title: Production of photomask
Inventor: TOKARI RYOJI
IPC: G03F1/00
Filed: 1987-08-04
Abstract: PURPOSE:To increase the yield of chips and to prevent the prolonging of the time for forming a mask by printing unit patterns for the plural chips at the center of a substrate and a pattern for one chip at the periphery, respectively by step and repeat. CONSTITUTION:The patterns 6 for the plural chips are collectively exposed by using the unit patterns 7 at the center of the mask substrate 5 and the pattern 6 corresponding to one chip is used at the periphery and is minutely exposed. Pattern printing is, therefore, executed rapidly with a smaller number of exposing by using the unit patterns 7 in the main part of the substrate 5. The minute printing can be executed in the margin part by using just one pattern 6. The mask even for the pattern of the extremely small chip size for one piece is thereby rapidly formed and further the wafer area is used effectively to the max. possible extent by the pattern for one piece.
