Surface micromachined membranes for tunnel transducers [PDF]

open access: yes, 1997
We have developed low-temperature surface micromachining procedures for the fabrication of suspended SiO2/Si3N4 membranes. This fabrication method was integrated with electron beam lithography, anisotropic ion etching, and electroplating to construct ...
