The present invention provides methods, devices and device components for
fabricating patterns on substrate surfaces, particularly patterns
comprising structures having microsized and/or nanosized features of
selected lengths in one, two or three dimensions. The present invention
provides composite patterning devices comprising a plurality of polymer
layers each having selected mechanical properties, such as Young's
Modulus and flexural rigidity, selected physical dimensions, such as
thickness, surface area and relief pattern dimensions, and selected
thermal properties, such as coefficients of thermal expansion, to provide
high resolution patterning on a variety of substrate surfaces and surface
morphologies.
