Patent ID: 7041436

Claim:
A method for the manufacture of microstructures in substrates, comprising the steps of a) providing a process mask ( 10 ); b) creating soft stamps ( 16 ) from a master comprising a microstructure ( 18 ) having an aspect ratio in a range of 1:5 to 1:20, said step of creating including creating holding blocks ( 20 , 22 ) attached to said microstructure ( 18 ), each of said holding blocks having an aspect ratio in a range of 1:1 to 1:2 so as to stabilize said microstructure ( 18 ) mechanically; c) attaching said soft stamps ( 16 ) to said mask ( 10 ); d) stamping a desired pattern into a resist layer ( 26 ) provided on a substrate ( 24 ) to be processed; and e) curing said pattern with UV light.
