摘要： PURPOSE: An image sensor is provided to improve sensitivity by increasing full well capacity in a photo diode area within a fine unit pixel. CONSTITUTION: An element separation area defines an active area in a unit pixel on a substrate. A vertical gate unit (120V) is extended along with a depth direction of the substrate from an upper surface of the substrate within the active area. A transfer transistor (Tx) contains a channel area. Multiple photodiode areas (PD1,PD2) are formed in a position with different thickness from the upper surface of the substrate within the active area. At least one color control path area (150) provides a electron transferred pass between more than two photodiode areas.
