Hydrogen Ambient Process For Low Contact Resistivity Pdge Contacts To Iii-V Materials

View page
US Patent:
61036145, Aug 15, 2000
Filed:
Sep 2, 1998
Appl. No.:
9/145634
Inventors:
David A. Ahmari - Champaign IL
Michael L. Hattendorf - Champaign IL
David F. Lemmerhirt - Sugar Grove IL
Gregory E. Stillman - Urbana IL
Assignee:
The Board of Trustees of the University of Illinois - Urbana IL
International Classification:
H01L 2128
H01L 213202
US Classification:
438606
Abstract:
The invention uses hydrogen ambient atmosphere to directly form PdGe contacts on Group III-V materials. Specific GaAs HBT's have been formed in a 100% H. sub. 2 ambient, and demonstrate low etch reactivity attributable to the significant incorporation of hydrogen. The LP-MOCVD method used to demonstrate the invention produced a specific contact resistivity of less than 1. times. 10. sup. -7. OMEGA. -cm-. sup. -2, at preferred conditions of a 100% hydrogen ambient, 300. degree. C. , and 15 minute reaction time. This is believed to be the lowest known resistance of any alloy method employed for PdGe on GaAs. Equally significant, the contacts demonstrate increased durability during etching.
