Abstract
Stamp for microcontact printing. The stamp includes a bulk portion having first and second surfaces, the first surface including a pattern of features to be transferred and the second surface including a different pattern of features. The features on the second surface have a lower stiffness than the features on the first surface. The dual-face stamp design of the invention provides an alternative location for dimensional errors to be absorbed, making microcontact printing a more robust production process.
