Abstract

Known chlorine atom concentrations were prepared in a discharge flow system and used to etch the (100) face of a gallium arsenide single crystal. The etch rate was monitored by mass spectrometry, laser interferometry, and surface profilometry. In the temperature range from 90 to 160-degrees-C the reaction can be described by the rate law Etch rate = kP(cl) where k = 9 x 10(6+/-0.5) mu-m min-1 Torr-1 e-9+/-1)kcal/RT.
