Lab on a chip is a developing field in nanoscience which requires controlled topographic modification of substrate surfaces. Photolithography is a printing technique used in changing surface morphology and topography, manufacturing of integrated circuits, and microfluidic channels at small scale. Photolithography is usually a sophisticated technique which needs clean-room facility and high resolution photomask designing. In this presentation we would like to report a simple technique by which we were able to design high resolution photomask using heat treated polystyrene plastic (Shrinky Dink) and achieved fabrication of microscale lithographic patterns on a silicon wafer. Different techniques of photolithography were tested and optimized for the best result. Microfluidic channels using this technique were also created with PDMS mould. The fabricated lithographic patterns were characterized by an Atomic Force Microscope (AFM). Future research work will consist of designing and creating low-cost photomasks using different materials.Not Submitted
