Abstract

See full text

An image sensor with quantum efficiency enhanced by inverted pyramids includes a semiconductor substrate and a plurality of microlenses. The semiconductor substrate includes an array of pixels. Each of the pixels is configured to convert light incident on the pixel to an electrical output signal, the semiconductor substrate having a top surface for receiving the light. The top surface forms a plurality of inverted pyramids in each pixel. The plurality of microlenses are disposed above the top surface and aligned to the plurality of inverted pyramids, respectively.
