Patent ID: 8057988

Claim:
A method of producing a microreactor, comprising the steps of: providing a silicon wafer, coating a photoresist on said silicon wafer, using a mask with UV exposure to develop a desired pattern in said photoresist, anisotropic etching said silicon wafer to produce microchannels in said silicon wafer, applying a liquid containing a catalyst to said microchannels filling said microchannels with said liquid containing a catalyst, aligning a substrate over said microchannels in said silicon wafer wherein said step of aligning a substrate over said microchannels in said silicon wafer comprises aligning a silicon wafer substrate or a glass substrate over said microchannels in said silicon wafer, allowing surface tension to spread said liquid containing a catalyst over said microchannels by surface tension, bonding said silicon wafer and said substrate, and baking microchannels, said liquid, and said catalyst leaving said catalyst in said microchannels coating said microchannels with said catalyst.
