Abstract: Organic films are applied from solvent solution to a substrate, then are ion implanted to have resistivity in the kilohm/square to gigaohm/square range. The films are then patterned by standard lithographic procedures, with surprisingly little loss of conductivity, in spite of contact with organic solvents or acidic or basic etchant solutions during the patterning process. Both structures which contact the substrate, and freestanding conductive polymer bridges, can be formed. The invention provides a method of producing electrical devices which does not require the use of single crystal semiconductor substrates or deposition of inorganic semiconductors. The resulting devices are highly resistant to damage from abrasion, solvents, acids, bases, and moisture.

Abstract: The invention is a flag system for displaying a flag from a hood of an automobile. The primary embodiment consists of a mast with a pin which is inserted into the mast. The pin prevents the flag from creeping up the mast. The flag system is held in position between the hood and car by a tongue. A threaded portion and a threaded nut are located on the mast. The threaded nut is tightened, clamping the tongue onto the car hood.
Abstract: A composition and a method for forming an anti-reflective layer for DUV microlithographic processes is disclosed. The compositions of the present invention includes a polymer dissolved in a suitable solvent. The polymers are polysulfone and polyurea polymers which possess inherent light absorbing properties at deep ultraviolet wavelengths. In accordance with the method of the present invention, these compositions are applied to a substrate to form an anti-reflective coating, and thereafter a photoresist material that is compatible with the anti-reflective coating is applied.
