Abstract: PURPOSE: To make uniform the beveling dimensions of the edge parts of semiconductor wafers, by fixing a plurality of piled-up semiconductor wafers to a fixing jig, dipping the wafers into an etching solution with their center line set vertical, and causing them to move vertically.  
     CONSTITUTION: Lower fixing plate 15 and upper fixing plate 14, which is provided with suspender 17, are enclosed in a basket-shaped fixing jig 10 consisting of upper frame plate 11 and lower frame plate 12 and a plurality of rods 16 placed between them. Many piled-up wafers 16, which are to be beveled, are placed between upper and lower fixing plates 14 and 15. Jig 10 is dipped into etching tank 18 filled with etching solution 19 consisting of fluoric acid and nitric acid with the center line of wafers 16 set vertical. Subsequently, by using suspender 17, jig 10 is caused to move up and down, and thereby the edge parts of wafer 16 are beveled. By this, solution 19 is stirred by the up-down movement of jig 10 and fresh solution 19 comes into contact with the edge parts of wafer 16, and thereby the beveling dimensions are made uniform.
