Opis:
The high frequency performances including microwave noise parameters for sub-quarter micron fully- (FD and partially-depleted (PD) silicon-on-insulator (SOI) n-MOSFETs are described and compared. Direct extraction techniques based on the physical meaning of each small-signal and noise model element are used to extract the microwave characteristics of various FD and PD SOI n-MOSFETs with different channel lenghts and widths. TiSi2 silicidation process has been demonstrated very efficient to reduce the sheet and contact resistances of gate, source and drain transistor regions. 0.25 žm FD SOI n-MOSFETs with a total gate width of 100 žm present a state-of-the-art minimum noise figure of 0.8 dB and high associated gain of 13 dB at 6 GHz for V(ds) = 0.75 V and P(dc) < 3 mW. A maximum extrapolated oscillation frequency of about 70 GHz has been obtained at V(ds) = 1 V and J(ds) = 100 mA/mm. This new generation of MOSFETs presents very good analogical and digital high speed performances with a low power consumption which make them extremely attractive for high frequency portable applications such as the wireless communications.

Opis:
Original extraction techniques of microwave small-signal model and technological parameters for SOI MOSFETs are presented. The characterization method combines careful design of probing and calibration structures, rigorous in situ calibration and a powerful direct extraction method. The proposed characterization procedure is directly based on the physical meaning of each small-signal behavior of each model parameter versus bias conditions, the high frequency equivalent circuit can be simplified for extraction purposes. Biasing MOSFETs under depletion, strong inversion and saturation conditions, certain technological parameters and microwave small-signal elements can be extracted directly from the measured S-parameters. These new extraction techniques allow us to understand deeply the behavior of the sub-quarter micron SOI MOSFETs in microwave domain and to control their fabrication process.

Opis:
Most applications for radio frequency/microwave (thereafter called RF) transistors had been military oriented in the early 1980s. Recently, this has been changed drastically due to the explosive growth of the markets for civil wireless communication systems. This paper gives an overview on the evolution, current status, and future trend of transistors used in RF electronic systems. Important background, development and major milestones leading to modern RF transistors are presented. The concept of heterostructure, a feature frequently used in RF transistors, is discussed. The different transistor types and their figures of merit are then addressed. Finally an outlook of expected future developments and applications of RF transistors is given.
