Abstract: A substantially stoichiometric film of titanium nitride is provided by heating a substrate upon which a solution containing titanium has been applied at a substantially ambient temperature to provide a gel-film containing titanium on the surface of the substrate in an ammonia atmosphere. The substrate is heated to a temperature at which the titanium in the titanium-containing gel-film is substantially completely transformed to a substantially stoichiometric titanium nitride film, and at a rate of temperature change that is great enough to prevent the formation of nonstoichiometric titanium nitride compounds or other undesired titanium compounds in the resulting titanium nitride film. The invention is particularly suited for use in microelectronic devices.

Abstract: An ultrasonic unipolar pulse/echo instrument uses active switches and a timing and drive circuitry to control electrical energy to a transducer, the discharging of the transducer, and the opening of an electrical pathway to the receiving circuitry for the returning echoes. The active switches utilize MOSFET devices along with decoupling circuitry to insure the preservation of the unipolar nature of the pulses, insure fast transition times, and maintain broad band width and time resolution. A housing contains the various circuitry and switches and allows connection to a power supply and a movable ultrasonic transducer. The circuitry maintains low impedance input to the transducer during transmitting cycles, and high impedance between the transducer and the receiving circuit during receive cycles to maintain the unipolar pulse shape. A unipolar pulse is valuable for nondestructive evaluation, a prime use for the present instrument.

Abstract: A method and apparatus for determining the carrier concentration and profile depth for pn semiconductor structures, and band discontinuities for heterojunction pn structures is disclosed. A more accurate measurement of carrier concentration and profile depth is obtained by initially measuring the pn junction intercept voltage of a pn semiconductor structure to be tested before the structure is exposed to a conventional capacitance-voltage (C-V) profiling process. The pn junction intercept voltage is employed to determine the pn junction capacitance which can then be compensated for in capacitance dependent formulae used for calculating the carrier concentration and profile depth. The intercept voltage can also be used to determine band discontinuities in a heterojunction pn structure. A fixed or retractable metal contact is employed to contact the p-type layer of a pn semiconductor structure to be tested and permit this initial measurement to be obtained.
