  • Polysilicon thin films of improved electrical uniformity
    Patent number: 4536231
    Abstract: A method for forming a polysilicon thin film semiconductor device precursor, and the precursor, are disclosed, wherein the deposited thin film layer is scanned with a continuous wave laser in a first direction, and scanned a second time in a direction different from that of the first direction. The cross-scanning reduces the anisotropy of the thin film produced by the first scanning and apparently induces larger grain size in the recrystallized polysilicon.
    Type: Grant
    Filed: May 22, 1984
    Date of Patent: August 20, 1985
    Assignee: Harris Corporation

  • Reversibly programmable polycrystalline silicon memory element
    Patent number: 4420766
    Abstract: A polycrystalline silicon memory element having an impurity concentration in the range of 10.sup.17 to 10.sup.20 atoms per cubic centimeter is reversibly switchable from a high to a low resistance state through a negative resistance region using a voltage above the threshold having a ramped trailing edge.
