ABSTRACT:
Provided is a CMOS image sensor that uses thiophene derivatives. The CMOS image sensor includes first through third photoelectric conversion units vertically and sequentially stacked on a semiconductor substrate. The first photoelectric conversion unit detects blue light and comprises a first electrode, a second electrode, and a p-type thiophene derivative layer between the first electrode and the second electrode.
