An amplifying type solid-state imaging device having a transistor formed on a semiconductor base and a charge release portion which stores a signal charge which is generated by light incident on the transistor and outputs a change of an electrical signal in accordance with the stored charge. The transistor includes: a first gate region including a portion for storing the signal charge therein and a first gate electrode formed on the semiconductor base surface; and a source and a drain formed of impurity layers of a higher concentration than the semiconductor base concentration. The charge release portion includes: a second gate region including a portion in the vicinity of the semiconductor base surface, and a second gate electrode formed via an insulating film on the semiconductor base surface; and a drain for charge discharge formed of an impurity layer of a higher concentration than the semiconductor base concentration. The stored signal charge is released to the drain for charge discharge of the charge release portion.
An amplifying type solid-state imaging device for storing a signal charge, the device comprising:
