Patent ID: 7955912

Claim:
A method of manufacturing a semiconductor device, the method comprising: forming an insulating film over a first semiconductor of a transistor and a second semiconductor for a capacitor to be electrically connected to the transistor; forming a conductive film over the first semiconductor and the second semiconductor with the insulating film interposed therebetween; forming a resist pattern over the conductive film by performing a light exposure using a photomask; patterning the conductive film to form at least a first gate electrode over the first semiconductor and a second electrode over the second semiconductor by using the resist pattern, the second electrode including a first portion and a second portion where the second portion is thicker than the first portion; introducing a first impurity element into the first semiconductor with the first gate electrode as a mask to form a pair of impurity regions with a channel forming region therebetween; and introducing a second impurity element into the second semiconductor with the second electrode as a mask wherein a portion of the second impurity element penetrates the first portion of the second electrode to form an impurity region in the second semiconductor so as to overlap with the first portion of the second electrode, wherein the photomask comprises a first pattern which substantially blocks light and a second pattern which blocks light only partly, the second pattern corresponding to the first portion of the second electrode.
