Opis:: The paper briefly presents the history of microelectronics and the limitations of its further progress, as well as possible solutions. The discussion includes the consequences of the reduction of gate-stack capacitance and difficulties associated with supply-voltage scaling, minimization of parasitic resistance, increased channel doping and small size. Novel device architectures (e.g. SON, double-gate transistor) and the advantages of silicon-germanium are considered, too.

Opis:: The growth of high frequency HBT structures using silane-based epitaxy has been studied. The integrity of SiGe layers in the base and the control of the collector profile using As- or P-doping grown at 650°C have been investigated. The results showed that the growth rate of SiGe layers has a strong effect on the evolution of defect density in the structure. Furthermore, B-doped SiGe layers have a higher thermal stability compared to undoped layers. The analysis of the collector profiles showed a higher incorporation of P in silane-based epitaxy compared to As. Meanwhile, the growth of As- or P-doped layers on the patterned substrates suffered from a high loading effect demanding an accurate calibration.

Opis:: Formation of self-assembling nanohills induced by irradiation of nanosecond Nd:YAG laser pulses on the Si0.7Ge0.3/Si hetero-epitaxial structures is reported. The atomic force microscope study of the irradiated surface morphology has shown a start of nanohills formation after laser irradiation of the intensity I=7.0 MW/cm2. The giant "blue shift" of photoluminescence spectra with maximum intensity in region of 700-800 nm (1.76 - 1.54 eV) is explained by the Quantum confinement effect in the nanohills. The maximum of this photoluminescence band slightly shifts to shorter wavelengths with the increase of the intensity of laser pulses used for sample treatment. Appearance of the 300 cm-1 Ge-Ge vibration band in Raman scattering spectra for sample irradiated with I=20.0MW/cm2 is explained by Ge phase formation. Formation of the Ge-rich phase is explained by localization of Ge atoms drifting toward the irradiated surface under the thermal gradient due to strong absorption of laser radiation.

Opis:: A model of the position of the edge of emitter-base junction in the base and collector current pre-exponential ideality factor in HBT transistor with a SiGe base is presented. The model is valid for transistors with nonuniform profiles of doping and Ge content. The importance of taking into account the dependence of the effective density of states in SiGe on local Ge content and that of electron diffusion coefficient in SiGe on drift field for modeling accuracy is studied.

Opis:: A wideband amplifier up to 50 GHz has been implemented in a 0.25 žm, 200 GHz ft SiGe BiCMOS technology. Die size was 0.7×0.73 mm2. The two-stage design achieves more than 11 dB gain over the whole 20 to 50 GHz band. Gain maximum was 14.2 dB at 47.5 GHz. Noise figure was lower than 9 dB up to 34 GHz and a current of 30 mA was drawn from a 4 V supply. To the author's best knowledge this is the highest gain bandwidth product of a monolithic SiGe HBT amplifier ever reported.

Opis:: The main goal of this review is to comprehensively present the properties of silicon, germanium, and silicon-germanium systems and analyze current possibilities of producing fibers based on them for applications as a photovoltaic fabric for a future soldier. The vision of the future is to produce a feather-light photovoltaic optic fiber, exhibiting mechanical properties typical of Kevlar, enabling power/recharging of portable electric devices while simultaneously protecting against mechanical damage and explosions. This article analyzes, in detail, issues such as the occurrence and mobility of germanium in the environment, the life cycle of SiGe photovoltaic fabrics, ecotoxicological and human health implications, sustainable development strategies and policy implications, and analytical challenges due to low concentrations in the environment. Moreover, the advantages and disadvantages of silicon-based solar cells are analyzed, taking into account various factors, including environmental factors. Finally, the soldier of the future is analyzed.

Opis:: We present the state-of-the-art in simulation of silicon-germanium (SiGe) semiconductor devices. The work includes a detailed comparison of device simulators and current transport models. Among the critical modeling issues addressed in the paper, special attention is focused on the description of the anisotropic majority/minority electron mobility in strained SiGe grown on Si. We use a direct approach to obtain scattering parameters (S-parameters) and other derived figures of merit of SiGe heterojunction bipolar transistors (HBTs) by means of small-signal AC-analysis. Results from two-dimensional hydrodynamic simulations of SiGe HBTs are presented in good agreement with measured data. The examples are chosen to demonstrate technologically important issues which can be addressed and solved by device simulation.
