Analysis and Simulation of Heterostructure Devices

Communication and information systems are subject to rapid and highly so phisticated changes. Currently semiconductor heterostructure devices, such as Heterojunction Bipolar Transistors (HBTs) and High Electron Mobility Transis tors (HEMTs), are among the fastest and most advanced high-frequency devices. They satisfy the requirements for low power consumption, medium integration, low cost in large quantities, and high-speed operation capabilities in circuits. In the very high-frequency range, cut-off frequencies up to 500 GHz [557] have been reported on the device level. HEMTs and HBTs are very suitable for high efficiency power amplifiers at 900 MHz as well as for data rates higher than 100 Gbitfs for long-range communication and thus cover a broad range of appli cations. To cope with explosive development costs and the competition of today's semicon ductor industry, Technology Computer-Aided Design (TCAD) methodologies are used extensively in development and production. As of 2003, III-V semiconductor HEMT and HBT micrometer and millimeter-wave integrated circuits (MICs and MMICs) are available on six-inch GaAs wafers. SiGe HBT circuits, as part of the CMOS technology on eight-inch wafers, are in volume production. Simulation tools for technology, devices, and circuits reduce expensive technological efforts. This book focuses on the application of simulation software to heterostructure devices with respect to industrial applications. In particular, a detailed discussion of physical modeling for a great variety of materials is presented.

First full and comprehensive modeling of relevant compound semiconductors Verified by precise simulation of real-state-of-the-art devices in over 25 different simulation examples Bridges the gap between theory and applications with a large number of application examples

Rüdiger Quay was born in Köln, Germany, in 1971. He studied physics and economics at the University of Bonn and the RWTH Aachen, where he received his "Diplom" in physics in 1997. In summer 1996 he held a visiting research position at Los Alamos National Laboratory, New Mexico, USA, for his master's thesis. In 1999, he was a visiting researcher at the Beckman Institute, University of Illinois, Urbana Champaign. In 2001 he received the doctoral degree in technical sciences with honors from the Technische Universität Wien, Austria. He has published more than 30 refereed publications and he is one of the authors of the book "Analysis and Simulation of Heterostructure Devices". His scientific interests include RF-semiconductor device and process development, heterostructure device modeling and simulation, and circuit and reliability issues. Rüdiger Quay currently is a research engineer at Fraunhofer Institute for Applied Solid-State Physics (IAF) in Freiburg, Germany, involved in the development and large-signal characterization of high-power and high-speed AlGaN/GaN amplifiers and the development of high-speed InP HBTs for high data rate communication at 80~Gbit/s and beyond.

Communication and information systems are subject to rapid and highly so­ phisticated changes. Currently semiconductor heterostructure devices, such as Heterojunction Bipolar Transistors (HBTs) and High Electron Mobility Transis­ tors (HEMTs), are among the fastest and most advanced high-frequency devices. They satisfy the requirements for low power consumption, medium integration, low cost in large quantities, and high-speed operation capabilities in circuits. In the very high-frequency range, cut-off frequencies up to 500 GHz [557] have been reported on the device level. HEMTs and HBTs are very suitable for high­ efficiency power amplifiers at 900 MHz as well as for data rates higher than 100 Gbitfs for long-range communication and thus cover a broad range of appli­ cations. To cope with explosive development costs and the competition of today's semicon­ ductor industry, Technology Computer-Aided Design (TCAD) methodologies are used extensively in development and production. As of 2003, III-V semiconductor HEMT and HBT micrometer and millimeter-wave integrated circuits (MICs and MMICs) are available on six-inch GaAs wafers.
