Production of electronic devices

摘要

A method of producing an element of an electronic device, including the steps of providing a substrate; depositing on said substrate a layer of a switchable material, which changes its physical or chemical properties upon irradiation with light or heating causing a change of its surface energy properties; irradiatively inducing at selected regions of a layer of switchable material a change in physical or chemical properties that alters the surface energy of said selected regions and thereby forming a surface energy pattern on its surface; and without removing said layer of switchable material in either irradiated selected regions or non-irradiated regions from the substrate depositing over the surface energy pattern produced in step a material for forming an element of the electronic device such that the surface energy pattern controls the deposition of said material.
