Abstract:
In order to improve the performance of a solid-state imaging device, the solid-state imaging device has a pixel including a photoelectric conversion unit and a transfer transistor, and fluorine is introduced to a gate electrode and a drain region (extension region and n + -type semiconductor region) of the transfer transistor included in the pixel.

Claim (Index 11):
A method of manufacturing a solid-state imaging device which has\n a semiconductor substrate including an imaging region with a plurality of pixels formed there, the imaging region including a photoelectric conversion unit for converting incident light into electric charge, and a transfer transistor for transferring the electric charge, the transfer transistor including a source region and a drain region formed mutually at a distance within the semiconductor substrate, a channel region sandwiched between the source region and the drain region, a gate insulating film formed on the channel region, and a first gate electrode formed on the gate insulating film, the above method comprising the following steps of: (a) forming the first gate electrode of the transfer transistor; (b) introducing fluorine to apart of the first gate electrode, using a mask with the part of the first gate electrode opened; and (c) after the step (b), performing thermal processing on the semiconductor substrate.
