Device and Circuit Cryogenic Operation for Low Temperature Electronics


Book Description

Device and Circuit Cryogenic Operation for Low Temperature Electronics is a first in reviewing the performance and physical mechanisms of advanced devices and circuits at cryogenic temperatures that can be used for many applications. The first two chapters cover bulk silicon and SOI MOSFETs. The electronic transport in the inversion layer, the influence of impurity freeze-out, the special electrical properties of SOI structures, the device reliability and the interest of a low temperature operation for the ultimate integration of silicon down to nanometer dimensions are described. The next two chapters deal with Silicon-Germanium and III-V Heterojunction Bipolar Transistors, as well as III-V High Electron Mobility Transistors (HEMT). The basic physics of the SiGe HBT and its unique cryogenic capabilities, the optimization of such bipolar devices, and the performance of SiGe HBT BiCMOS technology at liquid nitrogen temperature are examined. The physical effects in III-V semiconductors at low temperature, the HEMT and HBT static, high frequency and noise properties, and the comparison of various cooled III-V devices are also addressed. The next chapter treats quantum effect devices made of silicon materials. The major quantum effects at low temperature, quantum wires, quantum dots as well as single electron devices and applications are investigated. The last chapter overviews the performances of cryogenic circuits and their applications. The low temperature properties and performance of inverters, multipliers, adders, operational amplifiers, memories, microprocessors, imaging devices, circuits and systems, sensors and read-out circuits are analyzed. Device and Circuit Cryogenic Operation for Low Temperature Electronics is useful for researchers, engineers, Ph.D. and M.S. students working in the field of advanced electron devices and circuits, new semiconductor materials, and low temperature electronics and physics.

Picosecond Electronics and Optoelectronics


Book Description

Over the past decade, we have witnessed a number of spectacular advances in the fabrication of crystalline semiconductor devices due mainly to the pro gress of the different techni ques of heteroepitaxy. The di scovery of two dimensional behavior of electrons led to the development of a new breed of ultrafast electronic and optical devices, such as modulation doped FETs, permeable base transistors, and double heterojunction transistors. Comparable progress has been made in the domain of cryoelectronics, ultrashort pulse generation, and ultrafast diagnostics. Dye lasers can generate 8 fs signals after compression, diode lasers can be modulated at speeds close to 20 GHz and electrical signals are characterized with subpicosecond accuracy via the electro-optic effect. Presently, we are experiencing an important interplay between the field of optics and electronics; the purpose of this meeting was to foster and enhance the interaction between the two disciplines. It was logical to start the conference by presenting to the two different audiences, i. e. , electronics and optics, the state-of-the-art in the two res pective fields and to highlight the importance of optical techniques in the analysis of physical processes and device performances. One of the leading techniques in this area is the electro-optic sampling technique. This optical technique has been used to characterize transmission lines and GaAs devices. Carrier transport in semiconductors is of fundamental importance and some of its important aspects are stressed in these proceedings.




Heterojunctions and Semiconductor Superlattices


Book Description

The Winter School held in Les Houches on March 12-21, 1985 was devoted to Semiconductor Heterojunctions and Superlattices, a topic which is recognized as being now one of the most interesting and active fields in semiconductor physics. In fact, following the pioneering work of Esaki and Tsu in 1970, the study of these two-dimensional semiconductor heterostructures has developed rapidly, both from the point of view of basic physics and of applications. For instance, modulation-doped heterojunctions are nowadays currently used to investigate the quantum Hall effect and to make very fast transistors. This book contains the lectures presented at this Winter School, showing in particular that many aspects of semiconductor heterojunctions and super lattices were treated, extending from the fabrication of these two-dimensional systems to their basic properties and applications in micro-and opto-electron ics. Among the subjects which were covered, one can quote as examples: molecular beam epitaxy and metallorganic chemical vapor deposition of semi conductor compounds; band structure of superlattices; properties of elec trons in heterojunctions, including the fractional quantum Hall effect; opti cal properties of two-dimensional heterostructures; quantum well lasers; and two-dimensional electron gas field effect transistors. It is clear that two-dimensional semiconductor systems are raising a great deal of interest in many industrial and university laboratories. From the number of applications which were received and from the reactions of the participants, it can certainly be asserted that this School corresponded to a need and came at the right time.

Advanced MOS Device Physics


Book Description

VLSI Electronics Microstructure Science, Volume 18: Advanced MOS Device Physics explores several device physics topics related to metal oxide semiconductor (MOS) technology. The emphasis is on physical description, modeling, and technological implications rather than on the formal aspects of device theory. Special attention is paid to the reliability physics of small-geometry MOSFETs. Comprised of eight chapters, this volume begins with a general picture of MOS technology development from the device and processing points of view. The critical issue of hot-carrier effects is discussed, along with the device engineering aspects of this problem; the emerging low-temperature MOS technology; and the problem of latchup in scaled MOS circuits. Several device models that are suitable for use in circuit simulators are also described. The last chapter examines novel electron transport effects observed in ultra-small MOS structures. This book should prove useful to semiconductor engineers involved in different aspects of MOS technology development, as well as for researchers in this field and students of the corresponding disciplines.
