Abstract

A device has been developed for introducing small quantities of gas directly to the specimen in the environmental scanning electron microscope chamber. This micro-gas delivery system is a modification of the micro-injector that delivers gas directly to the specimen under the electron beam. Gasses that are precious or hazardous are particularly suited to this technique because of the control that is afforded the microscope operator. An application of the micro-gas injection system is described; precursor organometalic vapor is delivered to a micromachined miniature hotplate for in situ chemical vapor deposition in the microscope chamber. Nucleation and growth of the tin oxide film can be viewed directly and in live-time.
