Gradient Chemical Micropatterns: A Reference Substrate for Surface Nanometrology



D Julthongpiput, Michael J. Fasolka, Wenhua Zhang, Tinh Nguyen, Eric J. Amis


We present fabrication routes for a new type of surface specimen that exhibits a micropattern with a gradient in chemical contrast between the pattern domains. Design elements in the specimen allow chemical contrast in the micropattern to be related to well-established surface characterization, like contact angle measurements. These gradient specimens represent a reference tool for calibrating image contrast in chemically-sensitive scanned probe microscopy techniques, and a platform for the high-throughput analysis of polymer thin film behavior.
