ABSTRACT:
A microdevice is constructed from a substrate having a microchannel formed therein and a cover plate arranged over the substrate. The cover plate in combination with the microchannel at least partially defines a conduit within the microdevice. The conduit has a surface that extends from an upstream region toward a downstream region and terminates at an opening. The microdevice also includes an annular lining that conforms to the conduit surface at the downstream region and extends from the opening toward the upstream region in the conduit. An emitter may be produced in situ by depositing an emitter material on the annular lining. In addition, material may be removed from the cover plate and/or substrate about the opening. As a result, an exterior microdevice surface is formed and a downstream portion of the emitter is exposed that protrudes from the exterior surface.
