摘要： The invention comprises curing polyamic acid solutions into polyimide solutions by adding a hydrophilic reagent to a polyamic acid solution. The hydrophilic reagent is selected to have little or no reactivity with amines or carboxylic acids, and is of the type that will react with water to form by-products that shift the equilibrium between polyamic acid as a reactant and polyimide and water as products toward the production of polyimide.

摘要： The invention is a modified organic photoresist which is resistant to etching in oxygen-containing plasmas and therefore particularly useful for masking and etching organic polymer materials in VLSI and advanced packaging applications. The invention comprises adding a phosphorous-containing compound to a conventional photoresist. The phosphorous-containing compound is of a type and in an amount effective to substantially prevent etching of the modified photoresist in an oxygen-containing plasma without substantially adversely affecting the photosensitivity of the photoresist or the elasticity or the adhesion of the etch resistant film formed during oxygen-containing plasma exposure to an underlying material to be patterned and etched.

摘要： A field emitter flat panel display and associated method of operation provides an electron emission path along which a beam of electrons emitted by a microelectronic field emitter travels such that the electrons impinge upon a light emitting element without passing through a mirror. The light emitting element is spaced apart from the microelectronic field emitter and includes a mirror and a luminescence layer on the mirror. The flat panel display can also include a deflector, such as a deflector electrode, which is spaced apart from both the microelectronic field emitter and the associated light emitting element and which controllably deflects the beam of electrons emitted by the microelectronic field emitter toward the luminescent layer of the associated light emitting element and along a curved electron emission path which is independent of the underlying mirror. Since the energy of the electrons is not dissipated by passing through a mirror prior to impinging upon the luminescent layer, the field emitter flat panel display and, more particularly, the microelectronic field emitter can be efficiently driven at relatively low voltage levels while still producing a relatively bright display.
摘要翻译：场发射器平板显示器和相关联的操作方法提供电子发射路径，微电子场发射器发射的电子束沿着该发射路径行进，使得电子撞击在发光元件上而不通过反射镜。发光元件与微电子场发射器间隔开，并且在反射镜上包括反射镜和发光层。平板显示器还可以包括偏转器电极，偏转器电极与微电子场发射器和相关联的发光元件两者间隔开，并且可控地将微电子场发射器发射的电子束偏转到发光层并且沿着独立于下面的反射镜的弯曲电子发射路径。由于在撞击发光层之前电子的能量不会通过反射镜而消散，所以可以在相当低的电压电平下有效地驱动场致发射体平板显示器，更具体地说，微电子场发射器驱动，同时仍然产生比较明亮的显示。

摘要： 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.

摘要： A photoresist composition is disclosed that comprises an organic resin that is thermoset by acid catalysis and a photoactive, etch-resistant ionic modifier formed of an anion and a cation. The modifier is present in the organic resin in an amount effective to produce substantial photoreactivity and etch resistance in a mixture of the resin and the modifier. The cation will, upon exposure to electromagnetic radiation, produce a species that is weakly basic or neutral, and the anion will, upon exposure to electromagnetic radiation, produce an acid precursor that will form a relatively strong acid in an acid-base solvent system. As a result, the relatively strong acid will catalyze the organic resin upon exposure to an appropriate frequency of electromagnetic radiation and the relatively weak base or neutral species formed by the cation will not substantially neutralize the acid or interfere with the acid catalyzed reaction of the organic resin.

摘要： A microelectromechanical transducer including a plurality of parallel electrically conductive strips maintained in closely spaced relation by a plurality of spacers can generate useful displacements and forces. The transducer can be strengthened by arranging the conductive strips in cells surrounded by unidirectional cell stiffening members and unidirectional displacement limiting members. The unidirectional cell stiffening members may include notches. The unidirectional displacement limiting members may include unidirectional buckling straps or flexible arches. The cells of electrically conductive strips can be organized in modular or fractal arrays.

摘要： A method of forming hydrogen fluoride (HF), to allow fluxless soldering, from a solid source such as potassium hydrogen fluoride (KF.HF) using a specialized apparatus, including a cartridge which is heated in a controlled atmosphere apparatus. The gaseous reaction product, HF, may be extracted from the apparatus either by itself or in a carrier gas (such as argon or nitrogen). The solid reaction product, potassium fluoride (KF), is an inert material which remains in the cartridge. The combination of the cartridge and KF may be safely disposed of as a unit or refilled with KF.HF under controlled conditions.
