Abstract
A series of experiments has been carried out to study the etching prop erties of silicon in hydrazine, with particular emphasis on the applic ability of the etchant in micromachining of microsensors. A new method of suppressing the etching of aluminium in hydrazine is presented 'an d a simple theory to account for the observed effects is proposed. Pra ctical aspects involved in the setting up of hydrazine etching equipme nt are also discussed.
