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.
