Abstract

A process of making a high precision microcontact printing stamp in which an elastomeric monomer or oligomer is introduced into a mold wherein a photoresist master imprinted with a microcircuit design in negative relief is predisposed. The monomer or oligomer is cured at a temperature no higher than about ambient temperature whereby a distortion-free microcontact printing stamp having the microcircuit design of the photoresist master in positive relief is formed.
