Abstract

In this work we offer an integration-ready solution to obtain self-aligned ohmic contacts on n-type III-V layers. We demonstrate ohmic contacts on n-type In 0.53Ga 0.47As by means of selective growth of epitaxial Ge followed by selective Ni germaniation process. Circular Transfer Length Method (CTLM) is used to extract the values of the Specific Contact Resistivity ρ C of the contacts. Values of ρ C in the order of 4×10 -5 Ω-cm 2 have been measured. This scheme, if further optimized, can contribute to the development of MOSFETs devices based on high-mobility materials.
