Hole initiated avalanche multiplication characteristics of 4H-SiC avalanche photodiodes have been studied. The diodes had n+-n-p SiC epitaxial layers grown on a p-type substrate. These 1 mm2 devices had very low dark currents and exhibited sharp breakdown at voltages of approximately 500V. The diodes multiplication characteristics appeared to be identical when the wavelength of the illuminating light from the top varied from 288 to 325nm, implying that almost pure hole initiated multiplication was occurring. The multiplication factor data were modelled using a local multiplication model with impact ionization coefficients of 4H-SiC reported by various authors. The impact ionization coefficients extracted from submicron devices by Ng et al. were found to give accurate predictions for multiplication factors within the uncertainties of the doping levels. This result suggests that their ionization coefficients can be applied to thicker bulk 4H-SiC structures.

AbstractTwo major concerns for silicidation of ultra-shallow junctions, namely the silicon-consumption- induced junction leakage and the series resistance increase, were compared among conventional post-junction-silicide (PJS) contact, silicide-as-a-diffusion-source (SADS) contact, Silicon-On-Insulator (SOI) contact, and elevated-source-drain (ESD) contact. Even though we found that ESD contacts would be the ultimate solution for both problems, SOI and SADS contacts provide better resistance to silicon-consumption-induced series resistance increase over conventional PJS contact because both are able to maintain a high dopant concentration at the silicide/silicon interface and thus a low specific contact resistivity. While there is no junction leakage concern for SOI contact, the SADS junction is also distinguished by low leakage owing to its lack of implant damage in the silicon substrate and uniformly doped junction along the silicide/silicon interface contour. MOSFET devices with SADS source/drain were demonstrated with quarter-μm technology. Epitaxial cobalt disilicide (CoSi2) was formed using the Ti/Co bilayer technique as a diffusion source. While both ESD and SOI processes still suffer from process complexity, integration and materials issues, we conclude that SADS contacting is a promising alternative for deep submicron devices.

The analysis of the switching behaviour of submicron devices brings about the necessity of extending the solution of the hydrodynamic model to the transient case. The implementation of such model has been carried out and a few examples of simulation are presented here, showing the velocity-overshoot of a ballistic diode and the temperature spread in the drain region of a realistic MOS device.

Quantum transport is becoming more significant as device size shrinks. For example, as device sizes are scaled below 0.1 μm, the number of impurities becomes quite small, so that they are no longer homogeneously distributed throughout the device volume and the carriers are localized into quantum boxes, in that self-energy corrections produced by locally high carrier densities will lead to quantum dot formation. This leads to the need to discuss transport through an array of such quantum structures. Here, we discuss several issues which must be considered in treating the transport through such devices.
