Microfluid control device and method of manufacturing the same

Abstract

Provided are a plastic microfluid control device having a multi-step microchannel and a method of manufacturing the same. The device includes a lower substrate, and a fluid channel substrate contacting the lower substrate and having a multi-step microchannel having at least two depths in a side coupling to the lower substrate. Thus, the device can precisely control the fluid flow by controlling capillary force in a depth direction of the channel by controlling the fluid using the multi-step microchannel having various channel depths. A multi-step micropattern is formed by repeating photolithography and transferred, thereby easily forming the multi-step microchannel having an even surface and a precisely controlled height.
