Optoelectronic device and the manufacturing method thereof

摘要

An optoelectronic device comprising a substrate; a first window layer on the substrate, having a first sheet resistance, a first thickness, and a first impurity concentration; a second window layer having a second sheet resistance, a second thickness, and a second impurity concentration; and a semiconductor system between the first window layer and the second window layer; wherein the second window layer comprises a semiconductor material different from the semiconductor system, and the second sheet resistance is greater than the first sheet resistance.
