Filed: 2000-08-31
Abstract: PURPOSE: An etching method is provided to improve a resist selection ratio and an etching shape. CONSTITUTION: A treatment gas is introduced into an airtight treatment chamber(104) to form an SiO2 layer formed on a wafer W placed in the chamber. In this method of etching this SiO2 layer, the treatment gas contains at least C5F8 and CH2F2. The flow ratio of C5F8 and CH2F2 in the treatment gas is substantially 1/4 < =(flow rate of C5F8/flow rate of CH2F2)<1/2. Since the treatment gas containing C5F8 and CH2F2 is used, the resist selection ratio can be improved. Furthermore, when the flow ratio of C5F8 and CH2F2 is substantially 1/4 or higher, abnormal shapes in vertical lines or meanders of formed grooves can be prevented. If the flow ratio of C5F8 and CH2F2 is substantially 1/2 or lower, abnormal shapes due to bowing of the formed grooves can be prevented.
