title: A single-step lithography system based on an enhanced robotic adhesive dispenser.
abstract: In the paper, we present a single-step lithography system whereby the robotically controlled micro-extrusion of resist adhesive onto a substrate surface to directly create resist adhesive patterns of interest. This system is modified from a robotic adhesive dispenser by shrinking the aperture of the nozzle to a few micrometers aiming to realize patterns at microscale. From experimental investigation, it is found that working factors including writing speed, working time, and applied pressure can be adopted to conveniently regulate the feature size (the width of the line features and the diameter of the dot features). To test its functionality, the system was used to pattern line features on silicon dioxide (SiO2) and generate an array of square-like silicon microstructure by combining with wet etching. It provides a simple and flexible alternative tool to facilitate the development of microfabrication.
