A method is disclosed for aligning layers in fabricating a multilayer printable electronic device. The method entails providing a transparent substrate upon which a first metal layer is deposited, providing a transparent functional layer over the first metal layer, depositing metal nano particles over the functional layer to form a second metal layer, exposing the metal nano particles to intense pulsed light via an underside of the substrate to partially sinter exposed particles to the functional layer whereby the first metal layer acts as a photo mask, and washing away unexposed particles using a solvent to leave partially sintered metal nano particles on the substrate.
