First Claim
Patent Images
1. A semiconductor device comprising:
- an insulating film formed on a substrate and having a groove;
a first film formed on a side surface and a bottom surface in said groove;
a wiring layer formed on said first film; and
a second film formed on an upper surface of said wiring layer,wherein θ
satisfies a condition 0<
θ
<
90°
, wherein θ
represents an angle between said side surface of said first film and a tangent line of said upper surface at a contact point between said upper surface of said wiring layer and said side surface of said first film.

Abstract
The present invention provides a method of manufacturing a semiconductor device, including the steps of forming a metal oxide film made of a metal oxide having a decrease in standard free energy smaller than a decrease in standard free energy of hydrogen oxide or of carbon oxide, on an insulating film formed on a semiconductor substrate, forming a metal oxide film pattern by subjecting a treatment to the metal oxide film, and converting said metal oxide pattern into at least one of an electrode and a wiring made of a metal which is a main component constituting the metal oxide, by reducing the metal oxide film pattern at a temperature of 80° to 500° C.
