Patent ID: 7538373

Claim:
An imaging sensor, comprising: a first transistor having a source region, a drain region, a channel region and a gate; a second transistor having a floating body for holding charge generated in response to exposure of said floating body to electromagnetic radiation, said source region, said drain region and said channel region of said first transistor connected in series between a reset voltage supply and said floating body of said second transistor; a third transistor having a gate connected to a drain of said second transistor, a drain connected to an output voltage supply and a source connected to a drain of a fourth transistor, a source of said fourth transistor connected to an output of said imaging cell circuit and a gate of said fourth transistor connected to row select input of said imaging cell; a fifth transistor having a gate and a drain connected to said output voltage supply and a source connected to said gate of said third transistor and said drain of said second transistor; and a dielectric isolation abutting all sidewalls of said floating body of said second transistor except for a region of said sidewalls abutting said source region of said first transistor, a bottom surface of said floating body abutting a PN junction.
