Abstract

A process of making a microcontact printing stamp useful in the microcontact printing of a microcircuit. In this process an elastomeric microcontact printing stamp is formed by curing a degassed liquid elastomeric monomer or oligomer, optionally saturated with helium, a mixture of helium and an inert gas or a mixture of hydrogen and an inert gas, in a mold in which a photoresist master, defining a microcircuit in negative relief, is predisposed above a backplane.
