  • Dielectric Films for Ge Planar Devices

    Publication Year: 1970, Page(s):2 - 11
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (992 KB)

    A series of passivating and masking films was developed and evaluated for use in a Ge planar transistor technology. In the search for satisfactory films, silicon dioxide, aluminum oxide, silicon nitride and multilayer combinations of these films, as well as some doped and mixed-composition films, were studied. The films, formed by pyrolytic deposition or by sputtering, were evaluated and compared ... View full abstract»

  • The Theory of Hot Electrons

    Publication Year: 1970, Page(s):12 - 24
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1181 KB)

    This is a survey of methods of analysis of the hot-electron phenomenon in semiconductors. The earliest method depended on three basic assumptions: smallness of the deviation of ƒ(p), the carrier distribution function, from ƒ0(E(p)), the distribution in energy E; the conventional relaxation-time relation between ƒ − ƒ0 and dƒ...

  • On-line Far-infrared Michelson Interferometry in a Time-shared Mode

    Publication Year: 1970, Page(s):25 - 32
    Cited by:  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (644 KB)

    A method is described for implementing real-time far-infrared Fourier spectroscopy in a time-shared environment. The system makes use of the IBM 1800 TSX-based General Experimental Monitor (GEM) and reduces by at least an order of magnitude the time between experiment initiation and the display of useful spectral frequency and intensity information. The key feature of the system includes conversat... View full abstract»

  • On the Equations of Holland in the Solution of Problems in Multicomponent Distillation

    Publication Year: 1970, Page(s):33 - 40
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (742 KB)

    Holland developed certain equations to be used to accelerate or induce convergence in multicomponent distillation calculations. In practice this procedure has been the most successful of any adjunct to the basic Thiele-Geddes or Lewis-Matheson procedure for solving these problems. It is of importance, therefore, to ascertain the conditions under which the Holland equations can be guaranteed to pos... View full abstract»

  • On the Maximum Likelihood Method of Identification

    Publication Year: 1970, Page(s):41 - 51
    Cited by:  Papers (6)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (955 KB)

    The maximum likelihood principle of estimation applied to the linear black-box identification problem gives models with theoretically attractive properties. Also, the method has been applied to industrial data (various processes in paper production) and proved able to work in practice. This paper presents further developments of the method in the case of a single output. The reliability and speed ... View full abstract»

  • Argon Content of SiO2 Films Deposited by RF Sputtering in Argon

    Publication Year: 1970, Page(s):52 - 60
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (763 KB)

    When SiO2 is deposited by sputtering in an argon rf glow discharge, the films so produced contain considerable amounts of trapped argon, as determined by x-ray fluorescence analysis. This argon content was measured as a function of various sputtering parameters: argon pressure, rf power, electrode spacing, substrate temperature, and magnetic field, the latter two being most influential....

  • Superlattice and Negative Differential Conductivity in Semiconductors

    Publication Year: 1970, Page(s):61 - 65
    Cited by:  Papers (120)  |  Patents (16)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (544 KB)

    We consider a one-dimensional periodic potential, or “superlattice,” in monocrystalline semiconductors formed by a periodic variation of alloy composition or of impurity density introduced during epitaxial growth. If the period of a superlattice, of the order of 100 Å, is shorter than the electron mean free path, a series of narrow allowed and forbidden bands is expected due t... View full abstract»

  • Calculation of the Current Density in the Contacts of a Thin Film Resistor

    Publication Year: 1970, Page(s):66 - 69
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (393 KB)

    The two-dimensional boundary value problem appropriate to current flow in a film resistor is examined. A simple closed-form solution for current density into the contact is found to exist for the important case of a thin film resistor with extended lands. The spatial dependence of the current density into the contact is found to be similar to that obtained by Kennedy and Murley for the diffused re... View full abstract»
