| 1992 | Invention patented by Kazushi Wada on August 9th, 1992. Abstract: A CCD shift register has a final transfer electrode which is formed only by a first polysilicon layer, and an output gate electrode which is formed by a second polysilicon layer. Under the output gate electrode, there is formed a doped region which is formed by a doping step of self alignment, independently of a doped region under the transfer electrodes. Therefore, it is possible to choose the impurity concentration and to adjust the potential level under the output gate electrode freely. |
