Abstract
A solid-state image device for outputting the charges transferred in one direction by a transfer clock is disclosed. It has a detection port for collecting signal charges, a first active region of a first conductivity for receiving the transferred charges, a second active region of a second conductivity formed in the first active region which is connected to the detection port, and a third active region of second conductivity formed beneath the first active region which is connected to a ground voltage terminal, whereby only the transferred signal charges are amplified to produce stable output signals with large gain. The first, second and third active regions together constitute amplifying means. The second active region is supplied with current by the charging operation of a reset transistor.
