Abstract:
1. A method of manufacturing a silicon optoelectronic device, comprising: preparing an n-type or p-type silicon-based substrate; forming a polysilicon at one or more regions on the surface of the substrate; oxidizing the surface of the substrate where the polysilicon is formed to form a silicon oxidation layer on the substrate, and forming a microdefect flection pattern at the interface between the substrate and the silicon oxidation layer, wherein the microdefect flection pattern is formed by the oxidation during oxidation process accelerated by oxygen traveling through boundaries of the grains in the polysilicon; exposing the microdefect flection pattern through the silicon oxidation layer; and forming a doped region by doping the exposed microdefect flection pattern in an opposite type to the substrate.
