    Applications of thin magnetic films in random-access memories of digital computing systems have received considerable attention recently because of their potential speed advantages. The necessity for using hundreds of thousands, or even millions of these elements in a single computer dictates that careful attention be given to cost. This paper describes the production design package for a thin-fil... View full abstract»

    The most pressing problem in electric contact testing is to define the modes by which contacts fail. Until we understand why and by what mechanism contact spots stop passing electricity between the mating members, it will be impossible to devise relevant life-testing procedures. This paper describes an experimental teehnique whereby interfaces can be observed during exposure to moist, polluted air... View full abstract»

    There are many cases where a subassembly contains a number of identical or similar elements. Two examples of this are printed circuit boards on which are mounted integrated circuit packages, and ceramic substrates with integrated circuit chips mounted and interconnected. The cost of the finished subassembly is a function of the repairability, number of elements per subassembly, and probability of ... View full abstract»

    This paper describes the effects of a magnetic field on cathodic sputtering in a crossed field discharge. Optimum conditions of gas pressure, magnetic field, and discharge type are suggested for the fabrication of thin-film circuit elements. Pure copper, tantalum, and titanium films were sputtered in an argon atmosphere at the maximum deposition rates of 2500, 1200, and 1000 Å/min, respective... View full abstract»

    Tantalum oxide possesses several outstanding characteristics as a dielectric for thin-film capacitors: a relatively high dielectric strength, a high capacitance-to-area ratio, and good mechanical and electrical stability. The high capacitance density, however, becomes a disadvantage for capacitors in the range of about 100 pF and below. Silicon oxide has been widely investigated as a dielectric fo...

    This paper presents some further results of the IBM Electrical Contacts Field Program, introduced previously. The degradation of contact materials over a period of time at six field sites is described as a function of atmospheric pollutants. The results of short-term laboratory exposures of some of these metals in tarnishing environments are compared and contrasted with the field results. Methods ... View full abstract»
