Abstract: The development of an exposed electron beam sensitive resist film in a two-stage process, rather than in a single stage, with a water wash between stages, improves the sensitivity and resolution that can be achieved for the resist.

Abstract: Gold is deposited onto a heated surface of N type semiconductor material composed of either gallium arsenide, gallium phosphide, aluminum gallium arsenide or aluminum gallium phosphide. The surface of the gallium compound is cooled to room temperature whereupon tin is deposited onto the gold. The semiconductor material is then reheated until the tin alloys with and through the gold into the material. A solderable surface may be applied to the semiconductor material by applying a film nickel and then a film of gold onto the alloyed surface.

The article may also include a film of plated metal.

Abstract: An insulating substrate, on which is at least one single crystalline electrode and a single crystalline layer of piezoelectric material on the electrode, forms an efficient surface acoustic wave device.

Abstract: Nickel-phosphorus alloys are electrolessly deposited such that initial deposition takes place at a relatively rapid rate and at a particular acid pH, then when the nickel content of the bath has dropped to a low level, pH drops rather abruptly and the final material deposited has a high phosphorus content relative to the layers initially deposited. In this method the phosphorus content of the surface layers is closely controlled to maintain uniform behavior of the plating in subsequent soldering, wire-bonding and welding operations.

Abstract: The mount comprises a first portion adapted for receiving a yoke, a second portion adapted for connection to a cathode-ray tube, a plurality of adjustable springs interconnecting the first and second portions and means for locking the first and second portions together. The adjustable springs permit movement of the yoke along one axis while securing its position along an orthogonal axis. In one preferred embodiment, a platform is provided with projections extending therefrom. A housing on which a yoke may be mounted, is attached to the projections. The housing includes a plurality of bow springs located between the points of attachment to the projections and the yoke attachment area. Means also are included to secure the bow springs in their adjusted positions.

Abstract: A low dark current photoconductive body includes an aluminum oxide overlayer on a cadmium selenide base layer. A transition region is provided at the interface region between the base layer and the overlayer and consists of a graded transition of cadmium and selenium with increasing amounts of aluminum and oxygen. An alternative body is disclosed omitting the overlayer. A blocking contact is provided within a portion of the body including the overlayer and/or the transition region.

Abstract: A laser-trimmed film resistor wherein the laser kerf terminates in an area outside the electrical current path across the resistor.FIELD OF THE INVENTIONThis invention relates to film resistors. More particularly, this invention relates to laser-trimmed thin and thick film resistors containing a laser kerf which terminates outside the electrical current path across the resistor.BACKGROUND OF THE INVENTIONFilm resistors are commonly used in hybrid circuits and include thick film resistors which are conventionally formed by screen-printing a resistive material on an insulating substrate and then firing the material, and thin film resistors which are conventionally formed by sputtering or vacuum-depositing a resistive material on an insulating substrate.In hybrid circuits it is often necessary to adjust the resistance of the film resistors in the circuit. To increase the resistance of a film resistor the resistor is "trimmed" by forming a kerf, i.e.

This provides a metallized diamond body whose metallic layer will adhere to the body.

Abstract: A cooling chamber is bonded to an electrical device to be cooled. The chamber includes a metal wall connecting the device into the working electrical circuit. A thinned portion of the metal wall forms a fuse which will burn out due to an excessive flow of current through the electrical device upon failure.
