Abstract:
A method of making a micro-channel device said method comprising the steps of:a) providing a first wafer patterned with at least one channel on a silicon-based working surface of first said wafer; b) depositing a layer of a first gasket material on said silicon-based working surface and in said channel; c) patterning said first gasket material to produce a first relief gasket with said first gasket material outlining edges of said channel on said silicon-based working surface; d) providing a second wafer with a glass-based working surface and a second relief gasket on said glass-based working surface, wherein said second relief gasket is capable of overlaying said first relief gasket; and e) aligning said first relief gasket and said second relief gasket; and f) anodically bonding regions of said silicon-based working surface and said glass-based working surface; wherein, said first relief gasket and said second relief gasket form a channel seal between said first wafer and said second wafer.
