Abstract: The invention is a method for forming semiconductor devices from a substrate having a non-planar surface. An anti-reflection coating is formed between the substrate and photoresist layer to alleviate the problems caused by non-uniform reflection at the substrate surface during exposure of the photoresist layer. Three-layer and two-layer stacks are described for use with UV and i-line exposure.

Abstract: A mounting connector for suspending articles such as fenders from the life lines and life rails in boats provides a secure attachment while enabling rapid disengagement or adjustment in the position of the fender. The mounting connector includes a hook arrangement which hooks onto the life line or life rail and includes a blocker which can be inserted into the hook to prevent accidental disengagement. The fender line passes through two closely spaced parallel holes in the body portion of the connector and can be readily adjusted lengthwise relative to these holes when the connector is moved to a horizontal position, but which bind with such holes when in normal suspended condition.

Abstract: An integrated circuit and its method of formation are disclosed. The circuit utilizes a spin-on glass as an interlevel dielectric. Above and below the spin-on glass is located a phosphorous doped dielectric. The doped dielectric prevents sodium from becoming mobile under the influence of subsequently applied electric fields.

Abstract: A method of forming low stack height transistors having controllable linewidth in an integrated circuit without channeling is disclosed. A disposable hardmask of doped glass is utilized to define the gate and subsequently protect the gate (and the underlying substrate) during ion implantation which forms the source and drains. An anti-reflective coating helps protect against reflective gate notching. A variety of silicided and non-silicided) structures may be formed.

Abstract: A magnetic switching device utilizing a reed switch avoids multiple switching and provides greater movement between a magnet and a reed switch. The device has a reed switch switchable by a magnetic field with contact reeds extending longitudinally in a switching line, at one permanent bar magnet, and a path of movement for the magnet to move relative to the reed switch, the path of movement being parallel to the switching line of the reed switch and spaced apart a predetermined distance therefrom, the magnet being tilted at a predetermined angle to the switching line of the reed switch, the angle being sufficient to cause only a single switching action when movement occurs between the magnet and the reed switch in the path of movement, the switching action occurring when the approximate centre of the magnet substantially overlaps the contact reeds of the reed switch.

Abstract: A non-slip sleeve fits over a shaft for a float level sensor so a float moves up and down on the sleeve surface. This non-slip surface prevents deposits forming thereon when used in tanks with sludge or other solids suspended in liquids. The thin walled sleeve is formed of a polytetrafluoroethylene polymer (PTFE) thus avoiding having to deposit or coat a shaft with PTFE which is expensive and time consuming.

Abstract: A digital liquid level measuring device determines the liquid level by reading a scale of a vertical series of horizontal binary coded numbers representing linear divisions. The measurement is direct rather than inferential and provides more accurate reading than existing methods. The digital measuring system does not suffer from the disadvantages of signal stability, drift, accuracy, calibration, error detection and size of range. The device has a fixed vertical scale, a float movable in a substantially vertical path maintaining a controlled distance from the fixed scale, a reading head on the float to read each of the horizontal binary coded numbers individually on the scale representing liquid level and a connection from the reading level to a display which provides an indication of liquid level.

Abstract: A slide projector system adapted to the projection of a continuous train of slides. The train of slides moves in the form of a slide magazine across the body of the projector parallel to the plane of projection transported by a mechanism that assures movement from left to right in the forward direction and from right to left in the reverse direction. The train of slides moves from an open rectangular tray temporarily attached to the body of the projector on one side into another tray temporarily attached to the opposite side. The train of slides comprises an interconnected series of pockets that are naturally folded in an accordion position from which they unfold in traversing the body of the projector and fold again naturally upon leaving the projector body. The present invention includes the slide projector, the left and right slide trays, the slide train transport mechanism and the accordion slide magazine.
