Abstract: A mask structure may be formed on a field emitter substrate for use in forming emitter wells on and in the substrate. The mask structure may be formed from a multilayered structure on the surface of the substrate using a laser lithography process. From the substrate up, the multilayered structure may include an antireflective coating, a photoresistive layer, an optional etch resistant layer between the antireflective coating and the photoresistive layer, and an optional second antireflective coating between the optional etch resistant layer and the photoresistive layer. The pattern of the mask structure may be transferred to the multilayer structure by exposing the photoresistive layer to laser light. The antireflective coatings may reduce the amount of stray laser light that reflects off the substrate and onto the back of the photoresistive layer.

Abstract: A field emitter device includes a column conductor, an insulator, and a resistor structure for advantageously limiting current in a field emitter array. A wide column conductor is deposited on an insulating substrate. An insulator is laid over the column conductor. A high resistance layer is placed on the insulator and is physically isolated from the column conductor. The high resistance material may be chromium oxide or 10%-50% wt % Cr+SiO. A group of microtip electron emitters is placed over the high resistance layer. A low resistance strap interconnects the column conductor with the high resistance layer to connect in an electrical series circuit the column conductor, the high resistance layer, and the group of electron emitters. One or more layers of insulator and a gate electrode, all with cavities for the electron emitters, are laid over the high resistance material. One layer of insulator is selected from a group of materials including SiC, SiO, and Si.sub.3 N.sub.4.

Abstract: An electrically and mechanically robust microelectromechanical transducer is formed of a pleated dielectric sheet having patterned electrical conductors on the opposing faces thereof. The pleats define a plurality of spaced apart walls, with each wall including an electrically conductive portion at one side thereof. Positive and negative voltages, applied to opposite faces of the pleated sheet, cause the walls to move towards one another by electrostatic attraction. The walls can also move away from one another by electrostatic repulsion upon application of appropriate voltages. The microelectromechanical transducer may be fabricated by fabricating a sheet with integral pleats or by forming a "self-pleating" flat sheet which forms pleats after conductor fabrication thereon.

Abstract: The present invention comprises methods for treating photoresists and forming photoresist relief images, including a method comprising providing a photoresist coating having a crosslinked surface layer, treating the photoresist coating with an organometallic material, and developing the photoresist coating to provide a relief image comprising an etch resistant effective amount of organometallic material.

Abstract: A method of making a microsurgical cutter from a flat planar substrate having a top surface and a bottom surface comprises the steps of (a) forming a photoresist mask layer on the top surface in the pattern of the microsurgical instrument, the mask layer having an edge portion formed in a predetermined pattern therein; and then (b) etching isotropically the top surface of the substrate through the top surface to the bottom surface so that the top surface and bottom surface meet at a cutting edge portion, with the cutting edge portion having a configuration corresponding to the edge portion of the mask layer. The substrates may be formed from semiconductor materials such as silicon, silicon carbide, sapphire and diamond.
