Title: Dry etching method
Inventor: AKIBA NAMISATO
IPC: H01L21/3065
Filed: 1993-09-22
Abstract: PURPOSE:To perform anisotropic etching on a material layer to be etched on which an SiON(silicon oxy-nitride) anti-reflection film is laminated. CONSTITUTION:Before etching an Al-based multilayered film in which a barrier metal 2, Al-1% Si layer 3, and SiON reflection preventing film 4 are successively piled up in this order, the etching resistance of a resist mask 6 is improved by coating the surface of the mask 6 with a hardened surface layer 7 by performing oblique rotary ion implantation. Or, it is also possible to simultaneously perform the etching of the film 4 and formation of the layer 7 by performing plasma irradiation using a fluorocarbon-based gas. Even when O* is discharged during the etching of the film 4, therefore, the dimension converting difference is suppressed and an anisotropic shape is obtained, because the edge of the resist mask 6 does not retreat in the lateral direction.
