This invention relates in general to a method of etching zirconium diboride, zirconium diboride(ZrB2) and in particular to a method of dry etching a thin film of ZrB2 that has been deposited onto a substrate and patterned using photolithography. U.S. patent application S.N. 156, 124, filed 16 February, 1988, of Linda S. Heath for Method of Etching Titanium Diboride and assigned to a common assignee and with which this application is copending describes and claims a method of etching titanium diboride with a dry etch. Zirconium diboride, like titanium diboride, TiB2, has become of interest in laboratory research because of its resistance to change or degradation at high temperatures.
