摘要：

A new fabrication technique for ohmic Au/Pt/Ti contacts to p-InGaAs is presented employing anodic oxidization and sputter etching by low energy Ar+ ions prior to the metal deposition. This cleaning procedure was found to be superior to wet chemical pre-etching as it provides low resistivity contacts with excellent homogeneity and good uniformity after rapid thermal processing (RTP).
