Abstract: PURPOSE:To prevent the generation of coating unevenness when a wafer is coated with a resist film by forming the discoid semiconductor wafer having a chord and its neighboring peripheral part whose curvature is changed continuously only over a specified circumferential length from at least one end section of the chord. CONSTITUTION:A discoid semiconductor wafer 3 having a chord 4 is formed in the manner that the curvature of the peripheral part extending from the chord 4 is changed continuously only over a specified circumferential length from at least one end section of the chord 4.
