AbstractThe interaction and reactivity of Ti and Co with SiO2 and Si3N4 have been investigated. In the case of Ti salicide, SiO2 sidewall spacer showed no lateral silicide overgrowth and low leakage current between gate and source/drain up to silicidation temperature of 750 1C. However, Si3N4 sidewall spacer showed dopant dependence of the lateral silicide growth and leakage current. This discrepancy between SiO2 and Si3N4 and dopant dependence is closely related to the reactivity. For Co, lateral silicide overgrowth is greatly reduced. Instead, Co films on SiO2 and Si3N4 layer were agglomerated by annealing. An annealing at 1050°C caused not only agglomeration of Co film but penetration of Co agglomerates through the layers. Interestingly, the CoSi2 spike of B type epitaxial and twinned orientation was formed in the Si substrate by the penetrated Co source.

ABSTRACTIII-V compounds such as InGaAs, InAs, InSb have great potential for future low power high speed devices (such as MOSFETs, QWFETs, TFETs and NWFETs) application due to their high carrier mobility and drift velocity. The development of good quality high k gate oxide as well as high k/III-V interfaces is prerequisite to realize high performance working devices. Besides, the downscaling of the gate oxide into sub-nanometer while maintaining appropriate low gate leakage current is also needed. The lack of high quality III-V native oxides has obstructed the development of implementing III-V based devices on Si template. In this presentation, we will discuss our efforts to improve high k/III-V interfaces as well as high k oxide quality by using chemical cleaning methods including chemical solutions, precursors and high temperature gas treatments. The electrical properties of high k/InSb, InGaAs, InSb structures and their dependence on the thermal processes are also discussed. Finally, we will present the downscaling of the gate oxide into sub-nanometer scale while maintaining low leakage current and a good high k/III-V interface quality.

Abstract We fabricated high forward and low leakage current trench MOS-type Schottky barrier diodes (MOSSBDs) in combination with a field plate on a 12 μm thick epitaxial layer grown by halide vapor phase epitaxy on β-Ga2O3 (001) substrate. The MOSSBDs, measuring 1.7 × 1.7 mm2, exhibited a forward current of 2 A (70 A cm−2) at 2 V forward voltage and a leakage current of 5.7 × 10–10 A at −1.2 kV reverse voltage (on/off current ratio of > 109) with an ideality factor of 1.05 and wafer-level specific on-resistance of 17.1 mΩ · cm2.
