A method for forming a semiconductor device includes the steps of forming a flowable film made of an insulating material with flowability; forming a first concave portion in the flowable film through transfer of a convex portion of a pressing face of a pressing member by pressing the pressing member against the flowable film; forming a solidified film having the first concave portion by solidifying the flowable film through annealing at a first temperature with the pressing member pressed against the flowable film; forming a burnt film having the first concave portion by burning the solidified film through annealing at a second temperature higher than the first temperature; forming a second concave portion connected at least to the first concave portion in the burnt film by forming, on the burnt film, a mask having an opening for forming the second concave portion and etching the burnt film by using the mask; and forming a plug and a metal interconnect by filing the first concave portion and the second concave portion of the burnt film with a conductive film.

A semiconductor device includes metal interconnects made from a multi-layer film composed of a first metal film formed on a semiconductor substrate with an insulating film sandwiched therebetween and a second metal film deposited on the first metal film. An interlayer insulating film having a via hole is formed on the metal interconnects. A third metal film is selectively grown on the second metal film within the via hole, so that a plug can be formed from the third metal film.

In the chromium-containing material film of the present invention, an element is added thereto and is capable of bringing a mixture of the element and the chromium into a liquid phase at a temperature of 400° C. or lower. The use of such a chromium-containing material film as an optical film (e.g., a light-shielding film, an etching mask film, or an etching stopper film) of a photo mask blank can achieve an improvement in chlorine-dry etching while retaining the same optical characteristics and the like as those of the conventional chromium-containing material film, thereby increasing the patterning precision.

摘要:
A trench is formed in an interlayer dielectric formed on a substrate, then a barrier seed film is formed to cover the interlayer dielectric and the inner walls of the trench, and copper is embedded in the trench by electrolytic plating using the barrier seed film as an electrode. The barrier seed film is a single-layer film made of an oxide or nitride of a refractory metal and contains a low-resistance metal other than copper.
