Claim 0:
1. A method of manufacturing a semiconductor device, comprising:
providing a substrate in a process chamber; and
forming a film on the substrate in the process chamber by supplying an inert gas from a first supplier, supplying a first processing gas from a second supplier, supplying an inert gas from a third supplier and supplying a second processing gas from a fourth supplier to the substrate,
wherein the third supplier is installed at an opposite side of the first supplier with respect to a straight line that passes through the second supplier and a center of the substrate, the straight line being interposed between the first supplier and the third supplier, and the first supplier and the third supplier being disposed in line symmetry with the straight line as a symmetry axis, wherein the first supplier, the second supplier and the third supplier are parallel to each other, and
wherein in the forming a film, a substrate in-plane film thickness distribution of the film is adjusted by controlling a balance between a flow rate of the inert gas supplied from the first supplier and a flow rate of the inert gas supplied from the third supplier.
