Method of patterning the surface of an article using positive microcontact printing

摘要

A method is disclosed of patterning the surface of an object. The method comprises the steps of providing an object comprising a substrate having at least one layer formed thereon; forming a first SAM on the layer according to a desired pattern of a first material capable of binding to the layer; forming a second SAM of a second material on a region of the layer that is not covered by the first SAM, in a configuration that is complementary to the desired pattern; and etching the layer through the first SAM. The first material is selected to prevent the formation of the second SAM on the first SAM and to substantially not block the etching of an underlying region of the layer therethrough.
