Title: Image sensor
Inventor: SOEDA SHINICHI
IPC: H01L27/14
Filed: 1987-08-24
Abstract: PURPOSE:To manufacture an image sensor having high element yield and excellent reading characteristics by forming five layer structure composed of a common electrode, an amorphous silicon film, a discrete electrode, an insulating film and a third electrode. CONSTITUTION:An image sensor is constituted of the five layer structure of a common electrode 2, an amorphous silicon film 3, a discrete electrode 4, an insulating film 5 and a third electrode 6. Potential distribution in the surface direction in the amorphous silicon film 3 is equalized by voltage applied to the third electrode 6. Consequently, since excess currents flowing into the peripheral discrete electrode 4 through the amorphous silicon film 3 on the lower side of said specific discrete electrode 4 at a time when negative voltage pulses are applied to the specific discrete electrode 4 are reduced, only specified signal currents can be extracted, thus improving resolution. Excess currents can be diminished, thus increasing the read rate of signal currents.
