摘要: Electrical contacts with low specific-contact resistance to In-based Group III-V compound semiconductors (e.g., p-InGaAsP) are formed by electron beam depositing a thin Pt layer directly on the semiconductor and sintering at about 450.degree.-525.degree. C. for about 5-30 minutes. Light emitting diodes without dark spot defects can be fabricated using this technique.
