    Practical methods for making LSl yield projections are described in detail. The application of these methods to multilevel metal structures in particular is presented by means of example calculations of yield based on test pattern data. Using these methods the yield of any general multilevel metal interconnection pattern can be projected. It is shown that structural density, rather than chip area ... View full abstract»

    Results are discussed of an evaluation program for polymer materials considered for applications as protective coatings on hybrid microcircuits. The general organization of the program was in terms of seven potential mechanisms by which coatings could fail to provide protection. Emphasis is on describing those six tests which developed differences in material behavior considered to be significant ... View full abstract»

    A simple but relatively accurate, approximate technique is presented for analyzing the heat transfer due to natural convection and radiation from parallel-fin heat sinks. This technique accounts for a nonuniform base plate temperature. The finned surfaces and the base plate have been considered to be vertical U-shaped channels and a relationship for the NusseJt number has been used which has a sui... View full abstract»

    Metal-insulator-lnSb structures with excellent interface properties, as measured at 77 K, have been developed. A simple MIS structure has been fabricated and used to characterize the surface physics of the InSb MIS interface, The C-V characteristics of these structures follow the simple ideal MIS capacitive model. A completely inverted low-frequency type CoV response occurs at about 10 Hz, indicat... View full abstract»

    Techniques have been developed that provide disordered semiconducting materials having energy band tails arid electronic properties that are precisely controllable. The materials are heavily doped, closely compensated n-GaAs in which the compensation ratio can be made arbitrarily close to 1. Thus the Fermi level can be controlled within the band tail. This allows measurement of various electrical ... View full abstract»
