Patent ID: 7276748

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, a source region, a drain region and a 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 source 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; and dielectric isolation completely surrounding sidewalls and a bottom surface of said floating body of said second transistor except for a region of said sidewalls abutting said source region of said first transistor.
