Wet-chemical etching of SiO2 and PSG films, and an etching-induced defect in glass-passivated integrated circuits : Werner Kern. RCA Rev.47, 186 (June 1986)doi:10.1016/0026-2714(87)90099-0ELSEVIERMicroelectronics Reliability
Fused silica glass is a material of choice for micromechanical, microfluidic, and optical devices due to its chemical resistance, optical, electrical, and mechanical performance. Wet etching is the key method for fabricating of such microdevices. Protective mask integrity is a big challenge due extrem...
