  • Method and apparatus for fabrication of passivated microfluidic structures in semiconductor substrates
    Patent number: 7446382
    Abstract: A method and apparatus for fabrication of passivated microfluidic structures is disclosed. The method includes providing a substrate having a microfluidic structure formed therein. The microfluidic structure is embedded by an embedding layer. The method further includes passivating the embedded microfluidic structure by locally heating the microfluidic structure surface in a reactive atmosphere, wherein the passivated microfluidic structure is suitable for transporting a fluid. The structure optionally further includes metal pads to form an electrokinetic pump.
