Microfluidic device and manufacture thereof
First Claim
1. A method of manufacturing a microfluidic device, the method comprising the steps of:
- shaping a mixture including a binder and a precursor material on a first substrate;
presintering the mixture and the substrate to remove the binder and form a consolidated first assembly;
assembling the first assembly with a second assembly comprising a second substrate such that the presintered mixture is positioned between the first substrate and the second assembly; and
heating the assembled first assembly and second assembly to a temperature sufficient to form a one-piece microstructure defining at least one recess between the first and second substrates.

Abstract
The present invention relates to microfluidic devices and to their method of manufacture. The microfluidic devices are original by their specific structure (of sandwich type) and by the materials from which they are made (mainly glasses, glass ceramics, ceramics), and also by their specific method of manufacture, which is based on a vacuum-forming operation. The microfluidic device includes a first assembly including a microstructure and a first substrate, wherein the microstructure is constructed and arranged on the substrate under vacuum. A second assembly includes a second substrate positioned on the microstructure after the first assembly is presintered and adhered thereto by heat treatment to form a one-piece microstructure defining at least one recess between the first and second substrates.
