Abstract
Abstract The method produces a microcavity under a layer of enamel. It involves the use of a layer (Ca) of carbon-based material having the dimensions of the microcavity to be obtained. The layer (Ca) is covered with an enamel (SI) except for a small region (G). The system is raised to a high temperature so that the carbon-based material burns. The combustion gases escape through the small region (G). <??>Application to the production of oxygen sensors and microchromatographs. <IMAGE>
