This book was released on 2015-10-14 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon-Germanium Heterojunction Bipolar Transistors (SiGe HBTs) are perfectly suited for high-speed electronics. Since the fabrication costs per design cycle are rapidly increasing with progressing frequency and complexity of the systems, accurate compact models are essential in order to enable robust circuit design. This thesis focuses on selected important physical effects in advanced SiGe HBTs, which have been either insufficiently modeled or completely missing in conventional compact models. New compact model equations for the transfer current were derived and successfully applied to a large set of different technologies. Hereby, the "Generalized Integral Charge Control Relation" was used as a foundation. A physics-based model utilizing small-signal parameters obtained from measurements is derived for modeling the current dependent collector charge. A brief chapter about substrate effects in bipolar transistors comprises the derivation of a compact model for the bias-dependent substrate resistance as well as a proper partitioning of the substrate capacitance. New extraction methods for compact model parameters are introduced and the application of existing methods to advanced processes is discussed. The derived joint extraction method for the emitter and thermal resistance as well as a scalable model for the transfer current have been successfully applied to experimental data of fast HBTs. The derived model equations were applied to a selected very advanced SiGe HBT process developed by IHP. Highly accurate models for DC- and small-signal as well as for large-signal characteristics are presented.

This book was released on 2006 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using 2D device simulations, it is predicted that the cutoff frequencies of SiGe HBTs can be scaled beyond 500GHz. These devices have the potential to enable advanced millimetre-wave circuits. However, shot noise correlation, which is captured through noise transit time, becomes increasingly important as circuit designers continue to push the operating frequencies of the circuits. The technique for extracting the SiGe HBT noise parameters only from the measured y-parameters is extended to account for the presence of correlation. Unlike earlier publications, this method does not need to fit the noise transit time to measured noise data. The technique was validated using 2D device simulations and measured noise parameter data. It was found that the NFMIN of SiGe HBTs with & fnof; T/ & fnof;MAX of 160GHz is approximately 1.5dB lower at 60GHz when noise correlation is accounted for. However, for these devices, noise correlation proves to be insignificant below 18GHz.

Yuan discusses in depth the dc and RF performance and modeling of HBT devices, including simulation, thermal instability, reliability, low-temperature and high-temperature performance, and HBT analog and digital circuits. He provides step-by-step presentations of HBT materials-including Si HBTs and III-V and IV-IV compound HBTs, which are rarely described in the literature. Also covered are device and circuit interaction as well as specific high-speed devices in mobile and wireless communications. This immensely useful guide to a rapidly expanding field includes more than 200 figures, tables of different material systems in terms of their physical parameters, and up-to-date experimental results culled from the latest research. An essential resource for circuit and device designers in the semiconductor industry, SiGe, GaAs, and InP Heterojunction Bipolar Transistors is also useful for graduate students in electrical engineering, applied physics, and materials science.

Download or read book Characterization, Simulation and Optimization of Type-II GaAsSb-based Double Heterojunction Bipolar Transistors written by Nick Gengming Tao and published by . This book was released on 2006 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, GaAsSb/InP double heterojunction bipolar transistors (DHBTs) have been demonstrated to be promising alternatives to InP/InGaAs HBTs, for next generation microwave/millimeter wave applications and optoelectronic integrated circuits (OEICs). However, GaAsSb-based DHBTs featuring the novel base material and type-II band alignment have not been well studied. This thesis investigated type-II GaAsSb DHBTs in the following aspects: periphery surface recombination current, Kirk effect, two dimensional (2D) simulation and device optimization. The present work provided insights into device operation, and guidances for further device development. A series of physical models and parameters was implemented in 2D device simulations using ISE TCAD. Band gap narrowing (BGN) in the bases was characterized by comparing experimental and simulated results. Excellent agreements between the measured and simulated DC and RF results were achieved. Emitter size effects associated with the surface recombination current were experimentally characterized for emitter sizes of 0.5 by 6 to 80 by 80 square micrometer. The 2D simulations by implementing surface state models revealed the mechanism for the surface recombination current. Two device structures were proposed to diminish surface recombination current. Numerical simulations for type-II GaAsSb-InP base-collector (BC) junctions showed that conventional base "push-out" does not occur at high injection levels, and instead the electric field at the BC junction is reversed and an electron barrier at the base side evolves. The electron barrier was found to play an important role in the Kirk effect, and the electron tunnelling through the barrier delays the onset of the Kirk effect. This novel mechanism was supported by the measurement for GaAsSb/InP DHBTs with two base doping levels. The study also showed that the magnitude of the electric field at the BC junction at zero collector current directly affects onset of the Kirk effect. Finally, optimizations for the emitter, base and collector were carried out through 2D simulations. A thin InAlAs emitter, an (Al)GaAsSb compositionally graded base with band gap variance of 0.1eV, and a high n-type delta doping in the collector were proposed to simultaneously achieve high frequency performance, high Kirk current density and high breakdown voltage.

This book was released on 2011-07-31 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers all aspects from the expansion of the Boltzmann transport equation with harmonic functions to application to devices, where transport in the bulk and in inversion layers is considered. The important aspects of stabilization and band structure mapping are discussed in detail. This is done not only for the full band structure of the 3D k-space, but also for the warped band structure of the quasi 2D hole gas. Efficient methods for building the Schrödinger equation for arbitrary surface or strain directions, gridding of the 2D k-space and solving it together with the other two equations are presented.
