UNIT PIXEL OF AN IMAGE SENSOR CAPABLE OF PREVENTING THE GENERATION OF WHITE SPOTS AND AN IMAGE SENSOR INCLUDING THE SAME

摘要

PURPOSE: A unit pixel of an image sensor and an image sensor including the same are provided to prevent the generation of a dark current by forming a prevention gate.;CONSTITUTION: A photoelectric conversion part (115) is formed in a semiconductor substrate. A transmission gate (145) transmits photocharges to a floating diffusion region. The transmission gate is formed on the first surface of the semiconductor substrate. A prevention gate (150) applies a negative voltage. The prevention gate prevents the generation of a dark current around the first surface.;COPYRIGHT KIPO 2013
