    An improved quartz etchback process has been developed which reduces cycle time by etching the semiconductor structure with two different gas mixtures. The structure to be planarized in the process consists of a thick layer of planar resist 1 (Fig. 1), a planar quartz layer 2 and the metal line or stud 3 to be exposed...

    Forms are generated on an APA (all-points-addressable) printer from a personal computer in which every horizontal typing line on the form may be utilized for text and with each line of the form being capable of being typed on by a user of the form without any adjustment of the form in a typewriter. Forms may be...

    The lateral PNP transistor structure described uses a concentric ring- type geometry with a minimized emitter area and with a minimum detrimental effect of the parasitic diode which exists under the emitter. The result is improved gain and frequency response compared to conventional lateral PNP devices. Fig. 1 shows...

    This invention provides generation of a new set of low-discrepancy points which can be easily obtained. Low-discrepancy point sets, such as Hammersley sequences and good lattice points, are very efficient for calculating approximate values of integrals of certain classes of functions defined on the multi-dimensional...
