Abstract
A photo detector is disclosed. The photo detector has a substrate, a semiconductor layer disposed on the substrate, an insulating layer covered on the semiconductor layer, an interlayer dielectric layer covered on the insulating layer, and two electrodes formed on a portion of the interlayer dielectric layer. The semiconductor layer has a first doping region, a second doping region, and an intrinsic region located between the first doping region and the second doping region. The interlayer dielectric layer has at least three holes to expose a portion of the insulating layer, a portion of the first doping region, and the second doping region. The electrodes are connected to the first doping region and the second doping region through two of the holes.
