Abstract:
An image sensor includes a first substrate having a circuitry including a wire formed therein and a photodiode formed above the circuitry. An unevenness is formed at the top of the photodiode. The unevenness may, for example, be formed by selectively etching the top of the photodiode and may act to maximize light absorption by the photodiode.
