Low-noise microwave performance of AlN/GaN HEMTs grown on silicon substrate

F Medjdoub, Nicolas Waldhoff, Malek Zegaoui, B. Grimbert, N. Rolland, Paul-Alain Rolland

Microwave noise performance of state-of-the-art AlN/GaN high-electron-mobility transistors (HEMTs) grown on 100-mm Si substrate has been investigated. DC and RF measurements show the outstanding potential of this structure for high-power millimeter-wave (mmW) applications. A maximum output current…

Effects of AlGaN back barrier on AlN/GaN-on-silicon high-electron-mobility transistors

F Medjdoub, Malek Zegaoui, B. Grimbert, N. Rolland, Paul-Alain Rolland

In this work, the effects of an AlGaN back barrier in the dc and RF performances of AlN/GaN high-electron-mobility transistors (HEMTs) grown on 100 mm Si substrates have been investigated. It is shown that the outstanding dc performance in highly scaled AlN/GaN-on-Si HEMTs can be fully preserved…

Optimization of ohmic contact and adhesion on polysilicon in MEMS–NEMS wet etching process

Etienne Herth, Emmanuelle Algré, Bernard Legrand, Lionel Buchaillot

This paper presents the optimization of polysilicon doping and metallization to form ohmic contact with etching resistance. Indeed, polysilicon doped by ion implantation and ohmic contacts are an important and interesting part of integrated circuit technology or MEMS and NEMS. LPCVD-polysilicon…

Exploit the bandwidth capacities of the perfluorinated graded index polymer optical fiber for multi-services distribution

C. Lethien, Christophe Loyez, Jean-Pierre Vilcot, N. Rolland, P.A. Rolland

The study reported here deals with the exploitation of perfluorinated graded index polymer optical fiber bandwidth to add further services in a home/office network. The fiber properties are exhibited in order to check if perfluorinated graded index plastic optical fiber (PFGI-POF) is suitable to…
