摘要： An image sensing device includes a first substrate layer including first conductive impurities and structured to produce photocharges based on the incident light and capture the photocharges using a voltage difference induced in response to a demodulation control signal; a second substrate layer including second conductive impurities having characteristics opposite to those of the first conductive impurities, and structured to be bonded to the first substrate layer; and a depletion layer formed between the first substrate layer and the second substrate layer.
