Patent Number Title Of Patent Date Issued
5260235 Method of making laser generated I. C. pattern for masking November 9, 1993
An improved method of patterning layers on a semiconductor element by use of laser processing. A thin film of amorphous silicon is deposited on a fused quartz window. Selected regions of the amorphous silicon are crystallized by a laser beam focused through the quartz window. The non
5104481 Method for fabricating laser generated I.C. masks April 14, 1992
An improved method of making masks includes forming a layer of amorphous silicon of about 2,000 angstroms on a transparent substrate. A laser beam is directed through the transparent substrate traverses the amorphous silicon to form a pattern of crystallized silicon. The n-crystallized
4897150 Method of direct write desposition of a conductor on a semiconductor January 30, 1990
An improved method of patterning a conductive interconnect on a semiconductor element is disclosed. A catalytic layer of, for example, amorphous silicon is deposited on a semiconductor element. The areas over which a conductive pattern is to be formed is activated by directing a focu
4379285 Analog to digital converter April 5, 1983
An analog to digital conversion circuit of the stage by stage, successive approximation type which incorporates a plurality of cascaded stages. Each stage comprises a mirror current generator for generating first and second mirror currents of the same magnitude as the input current, mean
4138671 Selectable trimming circuit for use with a digital to analog converter February 6, 1979
The outputs of individual stages in a digital to analog converter are each trimmed by independent circuitry which includes a plurality of transistors connected to a common output terminal, the physical dimensions of each transistor being scaled in proportion to desired levels of current
