Abstract:
A method of manufacturing a semiconductor device comprising the steps of:(a) forming an aperture on an insulating layer formed on a semiconductor substrate and thereafter forming a metal film on said insulating layer under a low pressure condition in a film forming apparatus; and(b) transferring said semiconductor substrate from the film forming apparatus to a reflow apparatus under a vacuum atmosphere of 1.3.times.10.sup.-6 Pa or less; and(c) heating simultaneously a plurality of semiconductor substrates under the vacuum atmosphere of 1.3.times.10.sup.-6 Pa or less in said reflow apparatus with a heating element selected from the group consisting of an infrared lamp and a resistance heater to execute the reflow process to the metal film formed on the insulating layer to fill the aperture with the metal film.
