Abstract
A micromachining device that utilizes a solid state laser beam scanner to steer and scan laser beams onto a moveable stage. There are no moving parts as in the galvometric scanner devices in current use. The laser beam scanner has two components, a variable frequency signal generator that is electrically connected to at least one substantially transparent and partially conductive substrate plate (hereinafter plate) with a generally planar face thereon that has a series of quantum dots (of an arbitrary size but narrow size distribution) affixed with the plate, where each of the quantum dots possess an inducible dipole moment, and each of the quantum dots are in electrical contact with the plate, where the quantum dots undergo an excitation and successive recombination (or relaxation) by the input of magnetic, optical or electrical signals.
