Development and analysis of low resistance ohmic contact to n-AlGaN/GaN HEMT

A. Soltani, A. Ben Moussa, S. Touati, Virginie Hoel, Jean-Claude de Jaeger, J. Laureyns, Y. Cordier, C. Marhic, M. A. Djouadi, C. Dua

High quality ohmic contacts were realized in order to obtain an AlGaN/GaN high electron mobility transistor (HEMT) on different substrates (Si, Al2O3, SiC). A metallization scheme based on Ti/Al/Ni/Au was used. The ohmic contacts were obtained using an optimized rapid thermal annealing (RTA) at…

Physical study of the dissipated power area in high electron mobility transistors for thermal modelling

Brahim Benbakhti, Michel Rousseau, Jean-Claude de Jaeger

The hot area in power transistors due to the power dissipation is determined from a 2D-hydrodynamic model. The power is calculated everywhere in the device from the knowledge of the physical quantities (current density, electric field). The hot area is determined accurately to be coupled to a…

On-line tools for microscopic and macroscopic monitoring of microwave processing

S. Vaucher, P. Unifantowicz, C. Ricard, Luc Dubois, M. Kuball, J.-M. Catala-Civera, Dominique Bernard, M. Stampanoni, R. Nicula

Direct monitoring of temperature, chemistry and microstructure is required to understand microwave heating in more detail, in order to fully exploit the unique features this non-equilibrium processing method can offer. In this paper, we show first that microwave radiometry can be used to follow…

Quick planarisation based on hydrogen silsesquioxane (HSQ) for deep etched InP based structures

Malek Zegaoui, Joseph Harari, Nargess Choueib, V. Magnin, Didier Decoster

The ability of HSQ resist films to planarise active deep etched (1.5-2m) InP based structures with electrodes is demonstrated for the first time. Vertically etched III-V semiconductor devices require planarisation of the passivation material for metal interconnections and device integration. A new…

Composition and size-dependent extinction coefficient of colloidal PbSe quantum dots

Iwan Moreels, Karel Lambert, David de Muynck, Frank Vanhaecke, Dirk Poelman, José C Martins, Guy Allan, Zeger Hens

Inductively coupled plasma mass spectrometry (ICP-MS) was combined with UV–vis−NIR spectrophotometry and transmission electron microscopy to determine the nanocrystal composition and molar extinction coefficient ϵ of colloidal PbSe quantum dot (Q-PbSe) suspensions. The ICP-MS results show a…
