Abstract: The invention provides photoresists and resist preparative methods. Methods of the invention include treatment of a resist resin with methylene chloride or other organic solvent to remove low molecular weight materials. It has been found that the treated resin can be formulated into resists that provide manufactured electronic devices with significantly reduced defects.

Abstract: A radiation sensitive resist composition exhibiting high resolution and enhanced etch resistance comprising a silicon containing polymeric additive, a non-silicon containing base polymer, a photoacid generator and a base is provided. A method of forming a patterned resist film is also provided. A resist film having an upper surface region enriched with silicon is also disclosed.

Abstract: A device and a method which utilizes semi-interpenetrating polymer networks for strain relief of fiber or cable. The need for adhesives and mechanical means for cable or fiber retention is eliminated while performance and reliability is enhanced. In one embodiment a first polymer network is fabricated in an undersized plug which is in turn placed inside a hollow connector housing with an open end and at least one aperture for a cable to pass through. The void created between the plug and the connector shell is then subsequently filled by adding a second polymer to fill the unit. The unit is then placed in a curing chamber so that the polymer can swell and completely fill any voids between the plug and the connector shell.

Abstract: A bonding method joins together a plurality of conductively coated polymers in a single operation. The method employs heat generation via a high energy source, whose output is focused by an energy director which causes fusing of the polymer surfaces along with fusing of the metal surfaces at their respective interfaces to form a robust electrical and mechanical bond.

Abstract: A method and apparatus in which an aluminum-clad copper pin-piston is supported on the upper surface of a roller or a pair of rollers. As the roller rotates, it rotates the pin-piston and the surface of the roller carries an electrolyte. The positive side of a power supply is connected to the pin-piston and the negative side of the supply is coupled to the roller surface via the electrolyte bath. Anodizing current passes from the rotating roller to the rotating pin-piston via the electrolyte, which is continuously replenished. An anodized film forms on the aluminum surface of the pin-piston. Oxide growth rate and film thickness are controlled by controlling the current density and the duration of pin-piston contact with the charged roller.

Abstract: A connector for terminating wires and cables is constructed of two mating thermoplastic members. One of the members carries a pattern of conductive material which forms edge contact pads, signal lines, ground lines and a ground buss interconnecting all ground lines. The other thermoplastic member is formed to include a series of ribs that parallel and contact the ground lines and ground buss. The surface of the thermoplastic member carrying the ribs and the ribs are plated with a copper layer and when assembled with the mating member forms grounded tunnel-like passages enclosing the signal lines and into which the signal conductors of the wires or cables extend to terminate on the signal lines.

Abstract: A cold plate and an integrated circuit cooling module embodying a cross-hatch coolant flow distribution scheme. Cross hatch flow distribution is achieved by way of two sets of channels which run perpendicular to each other. The first set of channels is formed on a base plate. The second, perpendicular set is includes a set of inlet channels and a set of interleaved outlet channels formed on a distribution plate. In the preferred embodiment, the base and distribution plates are separated by an interposer plate that has nozzles which cause a liquid coolant to impinge, under pressure, on the floor of the base plate.
