Abstract: The present invention is a covered microchannel comprising: a) a substrate; b) an etched material adhered to the substrate; and c) a silicon-carbon material adhered to the etched material in such a manner to form a covered microchannel; wherein the silicon-carbon material comprises SiO1.8-2.4 C0.3-1.0 and H0.7- 4.0 containing at least one of the following functional groups: -Si-O-Si-, -Si-CH2-, -Si-H, or -Si-OH. The covered microchannel can be prepared by the steps of: a) coating a filler material onto a substrate having a groove, wherein the filler material covering the substrate fills the groove; b) removing filler material from the substrate but not from the groove; c) coating the substrate and the filler with an adhering, formable, capping material; and d) removing the filler from the groove. An etched laminate can also be used to prepare the covered microchannel. The present invention provides a covered microchannel that can be prepared under milder conditions than those previously contemplated, thereby allowing greater flexibility in the choice of material of the substrate. The covered microchannel can be used, for example, in micro-liquid or micro-gas chromatographic or electrophoretic applications.
