description | PROBLEM TO BE SOLVED: To enable heading of columnar polycrystalline silicons embedded in a mono-crystal silicon with ease and high accuracy. SOLUTION: In the working method, after a step (b) of grinding a portion of a mono-crystal silicon 11 with a grinding tool 20, the mono-crystal silicon 11 and columnar polycrystalline silicons 12 are polished simultaneously in a drying way by using a polishing tool 30, so that uniform steping be performed even when different-hardness materials are included by a step (c) for withdrawing the heads of the columnar polycrystalline silicons 12.
