SOLID-STATE IMAGE SENSING DEVICE AND CAMERA SYSTEM USING THE SAME |
摘要 |
PURPOSE: A solid-state image sensing device and a camera system using the same are provided to obtain high sensitivity by forming a potential barrier within a pixel structure. CONSTITUTION: A solid-state image sensing device includes a plurality of pixels. Each pixel has a photodiode, a first transistor, and a second transistor. The photodiode is constituted by a first-conductivity-type semiconductor region and a second-conductivity-type semiconductor region. The first and second conductivity types are opposite to each other. The first transistor has a first-conductivity-type drain region formed in the second-conductivity-type semiconductor region to transfer signal charge to the drain region. The second transistor has a source and drain regions which are formed in the second-conductivity-type semiconductor region and which have the first conductivity type. At least one second-conductivity-type potential barrier is provided under the drain region of the first transistor and the source region and/or the drain region of the second transistor.
