Patent number: 4613401Abstract: The dry etching rate of a Cr film has been increased by adding ethyl or methyl alcohol vapor to an etchant gas containing a halide of a hydrocarbon such as CCl.sub.4 and oxygen gas. The dry etching rate increase is attributed to the reduction reaction of a dry etching product, CrO.sub.2 Cl.sub.2, into chemically stable CrCl.sub.3, the reduction reaction suppresses deposition of Cr generated by the decomposition of chemically unstable CrO.sub.2 Cl.sub.2.Type: GrantFiled: August 20, 1985Date of Patent: September 23, 1986Assignee: Fujitsu LimitedInventor: Eiichi Hoshino
