Abstract
The present invention is a method for detecting photo signals using an imaging device, comprising steps of photo-generating holes in a well region of a photo-diode by a signal light, transferring the photo-generated holes through a bulk of the well region to a heavily doped buried layer which is formed in the well region near a source region by doping that region with impurity heavier than the well region ( ) of an insulated gate FET, storing the photo-generated holes in the heavily doped buried layer to thereby change the threshold of the FET corresponding to the amount of the photo-generated charge, and reading the change in the threshold as the amount of signal light received by the photo-sensor.
