Anisotropic silicon etching techniques are widely used in various microsensors to create thermally isolated structures of micro-hotplate. Ethylene-diamine-pyrocatechol is one of the most commonly used anisotropic etchants. To integrate sensor arrays of various types of SnO2 thin-film sensors on the microstructure, a way to photolithographically pattern the SnO2 thin-film is needed. The results from such experiments are discussed.
