  • Method of treating SiPOS passivated high voltage semiconductor device
    Patent number: 4297149
    Abstract: The breakdown voltage of high voltage semiconductor devices passivated with SiPOS deteriorates if the devices are allowed to soak at temperatures in the 400.degree. C. to 525.degree. C. range. The original breakdown voltage is recovered by annealing the devices at a temperature of above about 550.degree. C. prior to metallization and alloying the metal at less than 425.degree. C.

  • Method of manufacturing bulk CMOS integrated circuits
    Patent number: 4295266
    Abstract: The method presented may be utilized in manufacturing CMOS integrated circuits either in an isoplanar or in a LOCOS process. The method entails the simultaneous formation of the well region with the oxide isolation regions by a drive-in diffusion which is conducted in a dry oxygen ambient. The utilization of the process insures that compounds of silicon, nitrogen and oxygen will not be present in the bulk silicon where they can effect the quality of gate oxides which are subsequently formed.

  • Method of detecting a thin insulating film over a conductor
    Patent number: 4296370
    Abstract: A method of detecting the presence of a thin insulating film having a thickness less than about 500 angstroms disposed over a surface of a conductor comprises positioning a conductive grid adjacent the surface of the insulating film. Ions of one type polarity are deposited adjacent the insulating film through openings in the grid, the openings in the grid being sufficiently small to limit the surface charge voltage on the insulating film to less than about 50 volts. After immersing the insulating film in a suspension of charged particles having a polarity opposite to the one type, the deposition of charged particles adjacent the conductor surface then indicates the presence of the insulating film.

  • System for measuring stylus shoe length
    Patent number: 4296371
    Abstract: A system for measuring shoe length of a stylus adapted to track a path along a surface of a video disc comprises positioning the tip of the stylus adjacent the surface of a substrate having a signal therein for effecting capacitive variations between the stylus and the substrate, and measuring the capacitive variations between the stylus and the substrate while they are oriented in a first position to obtain a first signal. The stylus is then tilted an angle of .theta. degrees relative to the substrate, whereby the stylus and substrate are oriented in a second position relative to each other. The capacitive variations are measured while the stylus and substrate are oriented in the second position to obtain a second signal. The first signal is then compared with the second signal to obtain a difference signal proportional to the shoe length of the stylus.

  • Work holder
    Patent number: 4286414
    Abstract: A work holder includes an elongated, hollow, cylindrical handle and a head secured within one end of the handle. A fixed jaw is secured to the head and projects longitudinally from the end of the handle. The fixed jaw has a pointed tip on its free end. A movable jaw is over the fixed jaw and is pivotally seated on an annular flange on the head. The movable jaw has a pointed tip which contacts the tip of the fixed jaw. A spring extends around the two jaws. The spring normally holds the tips together but allows pivoting of the movable jaw to separate the tips and thereby allow insertion or removal of a workpiece.

  • Wafer and boule protection during the blade return stroke of a wafer saw
    Patent number: 4287256
    Abstract: The quality of the as-sawn surfaces of a wafer is improved by preventing the saw blade from striking the wafer surfaces during the blade return stroke by leaning the just-sawn wafer away from the blade and by slightly retracting the face of the ingot from the plane of the saw blade. A fluid-jet-induced deformation of the binding compound portion of the ingot is preferred as a means of leaning the wafer away from the saw blade. Using this technique a number of wafers may be successively sawn from an ingot and kept attached to the ingot by the binding compound without the surfaces of the wafers being scored during the return strokes of the blade.
