Systems and methods for forming patterns and structures in target
materials are described. The method produces a pattern or structure in a
target material by contacting a stamp including one or more features with
a target material using a normal load sufficient for keeping the one or
more features in contact with the target material, and providing a cyclic
shear force in an amount sufficient to extrude the target material and
form a negative relief of the one more features in the target material.
The systems and methods can be used to produce a variety of articles
including, but not limited to, semiconductor integrated electrical
circuits, integrated optical, magnetic, mechanical circuits and
microdevices.
