Title: Etching apparatus and etching method
Inventor: SAKAMORI SHIGENORI
IPC: H01L21/00
Filed: 2001-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent the variation of an etched depth in an etching process where the etching of the depth less than the thickness of a film to be etched is conducted. SOLUTION: A film thickness measurement mechanism is provided in an orineter chamber A or B, or a transportation buffer chamber 5 of an etching apparatus. For example, a wafer, which is subjected to a prescribed etching process in an etching chamber 1, is temporarily transferred to the orienter chamber A or B, or to the transportation buffer chamber 5 and the etched depth is measured by the film thickness measurement mechanism. When the etched depth does not fall into a prescribed acceptable limit relation to the set value, an additional etching process is conducted to the wafer. An etching time in the additional process is calculated by the real etched depth which is measured by the film thickness measurement mechanism, the set value of the etched depth, and the etching rate in the film to be etched.
