摘要: A semiconductor device includes a substrate, a first insulation layer formed on the substrate in a first region, a photon absorption seed layer formed on the first insulation layer in the first region and on the substrate in a second region separate from the first region, and a photon absorption layer formed on the photon absorption seed layer in the first region. The photon absorption seed layer has a particular structure that may assist in reducing dislocation density in a region that includes a photon absorption layer.
