Method for fabricating microfluidic structures

Abstract

A method for fabricating microfluidic structures is provided. The method includes: a belt is provided and an adhesion layer is formed on at least one surface of the belt; the belt is cut for forming a first microfluidic channel thereon, wherein the first microfluidic channel has an accommodating space; a second microfluidic channel is provided, wherein a line-width of the second microfluidic channel is smaller than a line-width of the first microfluidic channel; the second microfluidic channel is disposed in the accommodating space of the first microfluidic channel; and a substrate is adhered to the belt via the adhesion layer.

What is claimed is: 
     
         1 . A method for fabricating microfluidic structures, comprising:
 providing a double-sided tape, wherein the double-sided tape comprises an adhesion layer and at least one protecting layer outside of the adhesion layer, and the adhesion layer comprises at least one adhering surface;   forming patterned-microfluidic channels on the adhesion layer via a knife mold with pre-determined patterns;   removing the protecting layer for exposing the adhering surface; and   adhering a substrate to the adhering surface.   
     
     
         2 . A method for fabricating microfluidic structures, comprising:
 providing a double-sided tape, wherein the double-sided tape comprises an intermediate layer, two adhesion layers located at a top side and a bottom side of the intermediate layer and two protecting layers located at outside of each adhesion layer, wherein each adhesion layer comprises at least one adhering surface;   forming patterned-microfluidic channels on the intermediate layer via a knife mold with pre-determined patterns;   removing the protecting layer for exposing the adhering surface; and   adhering a substrate to the adhering surface.
