Title: Wiring formation method
Inventor: HIBINO SATOSHI
IPC: H01L21/768
Filed: 2002-06-03
Abstract: PROBLEM TO BE SOLVED: To decrease reflow temperature by improving coverage when a fine connection hole is filled with a wiring material in a wiring formation method. SOLUTION: The connection hole 12a is formed on an insulating film 12 covering the surface of a substrate 10. The hole 12a is formed by dry etching treatment for masking a resist layer, and after dry etching is performed in a condition that an undercut occurs under the resist layer in the treatment, the hole 12a is formed so that a diameter is increased in an opening part outward by performing the dry etching in a condition that the undercut does not occur under the resist layer. After the hole 12a is covered on the upper face of the substrate to form a barrier layer 16, a wiring material layer 18 such as an Al alloy is formed by a sputtering method. The hole 12a is filled with the layer 18 with the coverage property by heating the substrate 10 at a temperature not exceeding 400 deg.C during or after formation of the layer 18.  Thereafter, the layers 16, 18 are patterned to form a wiring layer.
