IMAGE SENSOR AND FABRICATING METHOD THEREOF

摘要

PURPOSE: An image sensor and a manufacturing method thereof are provided to reduce resistance by forming a pad to correspond to a circuit. CONSTITUTION: A front surface and a rear surface are defined on a substrate (110). An insulation structure is formed on the front surface of the substrate. A contact hole exposes a circuit by passing through the substrate. A plurality of pads (151,152) are formed on the rear surface of the substrate. The pads are electrically connected to the circuit through the contact hole.
