ABSTRACT:
An apparatus (100) including a support structure (104), a flexible stamp (106) having a stamping surface (110) including a predetermined pattern disposed opposite the support structure (104), a pressure controlled chamber (112) disposed above the support structure (104), and a mechanical attachment (114) affixed to the flexible stamp (106). A method is provided for stamping the surface (101) of an article (102) including the steps of i) placing the article (102) on the support structure (104) within the pressure-controlled chamber (112), ii) wetting the stamping surface (110) with a solution containing a self-assembled monolayer-forming molecular species, iii) aligning alignment patterns (118) on the flexible stamp (106) with alignment patterns (124) on the surface (101) of the article (102), iv) controllably contacting the wetted stamping surface (110) with the surface (101) of the article (102) by changing the pressure differential across the flexible stamp (106) so that contact commences at the center of the flexible stamp (106) and proceeds outwardly in a controlled manner, and v) removing the stamping surface (110) from the surface (101) of the article so that a self-assembled monolayer (134) having the predetermined pattern is formed on the surface (101) of the article (102).
