Title: Semiconductor device and manufacturing method thereof
Inventor: KIMURA MASATOSHI
IPC: H01L21/8234
Filed: 2002-10-17
Granted: 2004-03-01
Abstract: A P type channel dope impurity region and a P- type punch-through stopper impurity region are not formed in a part of a channel region between an N- type photodiode impurity region and an N+ type floating diffusion impurity region. As a result, it will be more difficult for a potential harrier or a potential drop to trap charges transferred from N- type photodiode impurity region to N+ type floating diffusion impurity region. Consequently, since the charges generated in the photodiode impurity region is more easily transferred, a semiconductor device is obtained which has a solid-state image pickup element using a charge transfer transistor in which degradation of an image quality due to noise is suppressed.
