发明名称 METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
摘要 A method of manufacturing a semiconductor device includes providing a substrate having an insulating film and a plurality of conductive films on a surface; reducing the substrate by supplying a first reducing gas to the substrate so that at least one of a plurality of process conditions of the first reducing gas is controlled so that a product of a plurality of process conditions becomes a predetermined value, wherein the process conditions of the first reducing gas include a partial pressure of the first reducing gas in a region where the substrate exists and a time taken to supply the first reducing gas to the substrate corresponding to a temperature of the first reducing gas; and selectively forming a metal film on the plurality of the reduced conductive films by supplying a second reducing gas and a metal-containing gas to the substrate.

主权项 1. A method of manufacturing a semiconductor device, comprising: providing a substrate having an insulating film and a plurality of conductive films on a surface thereof, wherein each of the plurality of conductive films has a different incubation time; reducing the plurality of the conductive films by supplying a first reducing gas to the substrate, wherein process conditions of the first reducing gas are controlled so that a difference in incubation time among the plurality of conductive films is 0.01% or more and 50% or less; and selectively forming a metal film on the plurality of the reduced conductive films by supplying a second reducing gas and a metal-containing gas to the substrate.
