Novel Soft Lithography

In majority of the soft lithographic techniques, for every new design of patterns, a new original stamp or mold has to be fabricated by some other lithography methods such as Photolithography or Electron Beam Lithography. The state of art now is to develop methods that are capable of producing structures which are not mere negative replicas of the original stamp, thereby enabling the concept of Beyond the Master patterning. We develop methods, by which we can create patterns with variable feature height, periodicity and aspect ratios using SINGLE stamp.
