Abstract: PURPOSE:To establish flattened connection between upper and lower wirings by a method wherein an insulating film is formed by self-alignment surrounding a metal column previously formed in a through-hole penetrating the lower-layer wiring. CONSTITUTION:On an Si substrate 11, an Al wiring 15 is formed with the intermediary of an SiO2 film 12 and then its top is covered by a resist 14. A process follows of forming SiO2 films 31, 32 by means of a microwave electron cyclotron method or the like. Etching is accomplished of the SiO2 film 31 by using Ar ions for the exposure of the sides of the resists 14. The resist 14 is then subjected to incineration in O2 plasma. An Mo film is deposited and then a resist mask 17 is formed, whereafter etching is accomplished by using Cl2+O2 for the formation of an Mo column 16. The microwave electron cyclotron method is applied again for the deposition of an SiO2 film 18 under an RF bias. Ar ions are used then to completely remove the SiO2 film 18 positioned on the resist mask 17. A remaining resist 17' is incinerated in O2 plasma for the realization of a flattened wiring provided with Mo built in a through- hole. In this design, a multilayer wiring is obtained wherein flattened connection is established between upper and lower wirings without increasing the number of manufacturing processes or subjecting the lower-layer wiring to etching.
