V. Conedera et al., FIRST STEPS TOWARDS THE FABRICATION OF ELECTROSTATIC MICROMOTORS USING SOG, Sensors and actuators. A, Physical, 46(1-3), 1995, pp. 82-84
We have studied the use of spin-on glass (SOG), as a sacrificial layer
and source of dopant, for the realization of an electrostatic micromo
tor. Some difficulties have been encountered, and we propose a new pro
cess based on SOG, a classical POCl3 dopant source and oxidation of po
lysilicon to avoid these difficulties.
