    摘要: A method of forming a thin silicide layer on a silicon substrate 12 including heating the surface of the substrate to a temperature of approximately 500.degree. C. to 750.degree. C. and directing an atomic beam of silicon 18 and an atomic beam of an alkaline-earth metal 20 at the heated surface of the substrate in a molecular beam epitaxy chamber at a pressure in a range below 10.sup.-9 Torr. The silicon to alkaline-earth metal flux ratio is kept constant (e.g. Si/Ba flux ratio is kept at approximately 2:1) so as to form a thin alkaline-earth metal silicide layer (e.g. BaSi.sub.2) on the surface of the substrate. The thickness is determined by monitoring in situ the surface of the single crystal silicide layer with RHEED and terminating the atomic beam when the silicide layer is a selected submonolayer to one monolayer thick.

    摘要: An input buffer includes an input circuit (80), a pair of complimentary outputs (52,54) and a differential ampliifer (12). The input buffer includes a pull-down diode (90) arranged in parallel with pull-up diodes (84, 86, and 88), coupled between the buffer input (82) and the differential amplifier input (32). Pull-up is achieved through the low impedance path of the pull-up diodes, eliminating a need for a high value resistor. Pull-down is achieved through the pull-down diode in series with a resistor (92). This arrangement provides high speed of operation, while reducing current consumption.
