  • Publication number: 20070145632
    Abstract: An elastomeric stamp (10) for printing a pattern on a substrate (500) with an ink (520) is at least partially formed from a first material such as PDMS. The stamp comprises a first surface (12) in a first plane, a second surface (14) in a second plane and a third surface (16) extending from the first surface (12) to the second surface (14). The first surface (12) typically forms to the contact surface of a protruding feature of the stamp (10), whereas the third surface (16) typically forms the edge of such a feature. The first surface (12) comprises a barrier layer (22) being substantially impermeable to the ink (520). Optionally, the second surface (14) may carry a further barrier layer (24) to suppress gas phase diffusion of the ink (520). In contrast, the third surface (16) is permeable to the ink (520). Consequently, a stamp (10) is obtained that is highly suitable for edge transfer lithography type patterning.
