Abstract
A process of making a microcontact printing stamp useful in microcontact printing of microcircuits. In this process an elastomeric microcontact printing stamp is formed by curing an elastomeric monomer or oligomer in a mold in which a photoresist master, defining a microcircuit in negative relief, is predisposed above a flat and rigid backplane laminate. The flat and rigid plane member of the backplane laminate is delaminated from the backplane after the printing stamp is removed from the mold.
