ABSTRACTWe describe the electrical characteristics of boron doped homoepitaxial diamond films fabricated using a plasma assisted CVD process, formation of ohmic contacts, high temperature (580°C) Schottky diodes, and a rudimentary diamond MESFET. We also report reversible changes of the conductive state of the diamond surface by various surface treatments for both natural and thin-film diamonds.

ABSTRACTDoped diamond films grown by chemical vapor techniques has been used to study hydrogen and oxygen terminated diamond. It is known that the electrical characteristics of metal-diamond interface are strongly affected by the diamond surface features. O2 plasma treatment was used as a cleaning procedure for as grown diamond samples leading to changes in the capacitance measurements after treatment. The alteration in the characteristics of the samples can be attributed to the surface adsorbates like hydrogen and water vapor present in the atmosphere. The results indicates that the O2 plasma treatment was effective in cleaning the surface revealing the expected features of a p-type diamond film.

Electrical characteristics of 4H-SiC Schottky barrier diodes, based on buried grid design are presented. The diodes, rated to 1200V/10A and assembled into high temperature capable TO254 packages, have been tested and studied up to 250°C. Compared to conventional SiC Schottky diodes, Ascatron's buried grid SiC Schottky diode demonstrates several orders of magnitude reduced leakage current at high temperature operation.

Digital silicon carbide integrated circuits provide enhanced functionality for electronics in geothermal, aircraft and other high temperature applications. A multilayer thin film substrate technology has been developed to interconnect multiple SiC devices along with passive components. The conductor is vacuum deposited Ti/Ti:W/Au followed by an electroplated Au. A PECVD silicon nitride is used for the interlayer dielectric. Adhesion testing of the conductor and the dielectric was performed as deposited and after aging at 320°C. The electrical characteristics of the dielectric as a function of temperature were measured. Thermocompression flip chip bonding of Au stud bumped SiC die was used for electrical connection of the digital die to the thin film substrate metallization. Since polymer underfills are not compatible with 300°C operation, AlN was used as the base ceramic substrate to minimize the coefficient of thermal expansion mismatch between the SiC die and the substrate. Initial die shear results are presented.

In the present study, we introduce various technological approaches for fabrication of structured boron-doped diamond (BDD) electrodes, i.e., nanocones and nanorods which are used as working electrodes for electrochemical measurements. Structured BDD were realized either by reactive ion etching employing gold nanoclusters as the mask or by thermo-catalytically induced modification of the diamond surface. All samples were characterized in terms of surface morphology (scanning electron microscopy images), chemical composition (Raman spectroscopy) and electrochemical properties (anodic stripping voltammetry).
