ABSTRACT-Although a variety of novel device proposals for GaSb/(Al,Ga)Sb/InAs heterostructures have been made, relatively little is known about processing these materials. We have studied the reactive ion etching characteristics of GaSb, (AI,Ga)Sb, and InAs in both methane/ hydrogen and chlorine gas chemistries. At conditions similar to those reported elsewhere for RIE of InP and GaAs in CH4/H2, the etch rate of (AI,Ga)Sb was found to be near zero, while GaSb and InAs etched at 200Å/minute. Under conditions where the etch mechanism is primarily physical sputtering, the three compounds etch at similar rates. Etching in Cl2 was found to yield anisotropic profiles, with the etch rate of (AI,Ga)Sb increasing with Al mole fraction, while InAs remains unetched. Damage to an InAs “stop layer” was investigated by sheet resistance and mobility measurements. These etching techniques were used to fabricate a novel InAs-channel FET composed of these materials. Several scanning electron micrographs of etching results are shown along with preliminary electrical characteristics.

Thermal coating growth of ZnTe thermoelectric films were deposited on n-type Si substrate is studied. Structural analysis through x-ray diffraction (XRD) and scanning electron microscopy (SEM) were sensitive to the RTA treatment. The electrical properties and microstructure of these films were investigated with special emphasis on the effects of various annealing temperatures from 600°C to 800°C by RTA technique. The highest carrier concentration, lowest resistivity and mobility at an annealing temperature of 700°C are 3.5×1015cm-3, 0.25 Ω-cm, and 49 cm2V-1S-1. The resultant electrical properties have made ZnTe films as very interesting materials for thermoelectric device applications.

Carbon nanoparticles (CNP) were synthesized in arc plasma discharge using a simple, low-cost and toxic-free precursor gas. The structural and electrical characteristics were examined. The diameter and the height of the grown CNP was 28.5 μm and  316.7 μm , respectively. SEM image showed existence of a high density and uniform nanostructures within the cylindrical bulk CNP tube. The average diameter of the nanoparticles is 600 nm. The electrical characteristics revealed  low resistance with R = 7.23 mΩ with Cu electrodes.  In addition, the device exhibited a   high conductivity of 6.8 x 105 Scm-1. These results indicate the potential of CNP material for power device applications.

In our previous study, a novel barrier processing on a porous low-dielectric constant (low-k) film was developed: an ultrathin Mn oxide on a nitrogen-stuffed porous carbon-doped organosilica film (p-SiOCH(N)) as a barrier of the Cu film was fabricated. To form a better barrier Mn2O3-xN film, additional annealing at 450 °C was implemented. In this study, the electrical characteristics and reliability of this integrated Cu/Mn2O3-xN/p-SiOCH(N)/Si structure were investigated. The proposed Cu/Mn2O3-xN/p-SiOCH(N)/Si capacitors exhibited poor dielectric breakdown characteristics in the as-fabricated stage, although, less degradation was found after thermal stress. Moreover, its time-dependence-dielectric-breakdown electric-field acceleration factor slightly increased after thermal stress, leading to a larger dielectric lifetime in a low electric-field as compared to other metal-insulator-silicon (MIS) capacitors. Furthermore, its Cu barrier ability under electrical or thermal stress was improved. As a consequence, the proposed Cu/Mn2O3-xN/p-SiCOH(N) scheme is promising integrity for back-end-of-line interconnects.
