Paper Abstract

This paper describes the fabrication of micro-channels in resin for micro-fluidic devices such as the μ-TAS (Micro Total Analysis System) by a UV laser ablation. Numbers of heat-hardening resin-films are piled up a soda glass. A laser fabricates a part of the channel at the each film every lamination, and then 3-D confluence channels are fabricated. The channel sizes are widths of 20 - 150 μm and depths of 20 - 30 μm. The through holes are made in the laminate film by the laser. Inlet pipe for a micro-pump are inserted into the hole. Deionized water is injected into the channels with a microinjection pump. This flow rate is 5 μL/min. There is no damage to the channel, inlet, and outlet.
