Equally important, said Dr. Dowling, is the development of a suitable material for the photoresistive layer, one that could convert the special properties of two-photon light into lines on a wafer.
Instead of using light to etch a transistor circuit on a wafer of silicon, they propose to fabricate tiny wires.
I saw it lying on a wafer of silicon and it resembled nothing so much as breath on a windowpane.
