Abstract

Methods of forming photo detectors are provided. The method includes providing a semiconductor layer on a substrate, forming a trench in the semiconductor layer, forming a first single crystalline layer and a second single crystalline layer using a selective single crystalline growth process in the trench, and patterning the first and second single crystalline layers and the semiconductor layer to form a first single crystalline pattern, a second single crystalline pattern and an optical waveguide.
