Replication of a thin polydimethylsiloxane stamp and its application to dual-nanoimprint lithography for 3D hybrid nano/micropatterns.

This paper presents the fabrication of a thin and flexible polydimethylsiloxane (PDMS) stamp with a thickness of a few tens of um and its application to nanoimprint lithography (NIL). The PDMS material generally has a low elastic modulus and high adhesive characteristics. Therefore, after being treated, the thin PDMS stamp is easily deformed and torn, adhering to itself and other materials.

X Y parallel compliant stage with compact configuration.

This paper presents a piezo-driven compliant stage for nano positioning with two degree-of-freedom parallel linear motions. Nano positioning is one of the most important factors in completion of nanotechnologies. It can be accomplished by flexure-based compliant stages driven by piezo-actuators.
