Abstract: A snap fastener attaching system employs a moveable carriage assembly which is controlled in linear motion by a belt system coupled to an actuator mechanism. The carriage assembly includes clamping means which are sequentially operated to clamp a garment on the assembly after emplacement by an operator. The depression of a start button enables the actuator to traverse a shaft. Associated with the actuator is a pivotable arm which is located in proximity to a selected shaft of a cam-containing turret assembly. As the actuator moves, the carriage moves proportionately due to the belt coupling system. Each time the actuator arm contacts a cam along the turret shaft, a fastener is emplaced on the garment by the snap fastener attaching machine associated with the carriage assembly. When the last fastener is emplaced, the apparatus is automatically returned to the starting position to enable accommodation of the next garment.

Abstract: A method for making a metal oxide semiconductor field effect transistor (MOSFET) is disclosed that results in a semiconductor device structure in which the source and drain regions are buried in the structure beneath a typically thick oxide and bulge out in the semiconductor underneath, but not contiguous with, the interface of a typically thin gate oxide with the semiconductor. This bulging of the buried drain, in an N-channel device, results in an electric field profile during operation which curves away from the interface in the neighborhood of the drain, thereby reducing deleterious transport of electrons from the channel to the gate oxide. The method can also be adapted for fabricating integrated memory cell arrays. This adaptation involves the implantation of one or more layers of dopant ions in the region of the semiconductor between the oxide interface and the bulging portion of the buried drain.

Abstract: An integrated circuit aluminum-silicon electrical contact may be fabricated in a diffusion region formed in a monocrystalline silicon semiconductor layer by converting the upper portion of the diffusion region into an amorphous region. Alloy pitting is substantially decreased since the solubility of silicon in aluminum is highly dependent upon crystallographic orientation of the silicon and decreases as the silicon approaches an amorphous form. The amorphous region may be formed by implanting arsenic ions with an energy of at least 180 keV and a dosage of approximately 10.sup.15 ions/cm.sup.2.
