Abstract: An insulating film and another insulating film are formed over a semiconductor substrate in that order to cover first, second, and third gate electrodes. The another insulating film is etched back to form sidewall spacers over side surfaces of the insulating film. Then, the sidewall spacers over the side surfaces of the insulating films corresponding to the sidewalls of the first and second gate electrodes are removed to leave the sidewall spacers over the side surfaces of the insulating film corresponding to the sidewalls of the third gate electrode. Then, the sidewall spacers and the insulating films are etched back, so that the sidewall spacers are formed of the insulating film over the sidewalls of the first, second, and third gate electrodes.

Abstract: In a method of forming a tungsten film, an initial tungsten film and a main tungsten film are formed on an underlying film of a substrate. The initial tungsten film is formed on the underlying film by sequentially supplying a tungsten chloride gas and a reduction gas into a chamber while supplying a purging gas between the supplies of the tungsten chloride gas and the reduction gas, or by simultaneously supplying the tungsten chloride gas and the reduction gas. The main tungsten film is formed on the initial tungsten film by sequentially supplying the tungsten chloride gas and the reduction gas into the chamber while purging an inside of the chamber between the supplies of the tungsten chloride gas and the reduction gas. A supply amount of the tungsten chloride gas in forming the initial film is smaller than that in forming the main tungsten film.

Abstract: A manufacturing procedure of a semiconductor device is simplified. In a manufacturing method of a semiconductor device, in each of regions AR with pixels for detecting different colored lights, a liner film LF1 is formed over an interlayer insulating film IL formed to cover a photodiode PD. Then, an opening OP is formed to reach a midway point of the interlayer insulating film IL while penetrating the liner film LF1. The liner film LF1 is formed such that the thickness of the liner film LF1 is varied among the respective regions AR. A height position of a bottom surface of the opening OP in a region with the thin liner film LF1 is lower than a height position of a bottom surface of the opening OP in a region with the thick liner film LF1.
