    摘要: According to an example embodiment, a light-sensing apparatus may include an array of light-sensing pixels (100), a first gate driver (210), and a signal output unit (230). Each of the light-sensing pixels may include a light sensor transistor (140) configured to sense light, a switch transistor (130) configured to output a light-sensing signal from the light sensor transistor, and a conductive light-shielding film (114) on a light-incident surface of the switch transistor. The light sensor transistor and the switch transistor may have the same oxide semiconductor transistor structure. The first gate driver may be configured to provide a gate voltage and a negative bias voltage to each of the light-sensing pixels. The signal output unit may be configured to receive the light-sensing signal from each of the light-sensing pixels and output a data signal.

    摘要: Provided is a complementary metal oxide semiconductor (CMOS) image sensor having a structure capable of increasing areas of photodiodes in unit pixels and expanding light receiving areas of the photodiodes. In the CMOS image sensor, transfer transistors may be formed on the photodiode, and reset transistors, source follower transistors, and selection transistors may be formed on a layer on which the transfer transistors are not formed. In such a CMOS image sensor, the areas of the photodiodes may be increased in unit pixels so that a size of the unit pixels may be reduced and sensitivity of the pixel may be improved.
