The advent of the microelectronics technology has made ever-increasing
numbers of small devices on a same chip. The rapid emergence of
ultra-large-scaled-integrated (ULSI) technology has moved device
dimension into the sub-quarter-micron regime and put more than 10
million transistors on a single chip. While traditional closed-form
analytical models furnish useful intuition into how semiconductor
devices behave, they no longer provide consistently accurate results for
all modes of operation of these very small devices. The reason is that,
in such devices, various physical mechanisms affect the device
performance in a complex manner, and the conventional assumptions (i.
e., one-dimensional treatment, low-level injection, quasi-static
approximation, etc. ) em- ployed in developing analytical models become
questionable. Thus, the use of numerical device simulation becomes
important in device modeling. Researchers and engineers will rely even
more on device simulation for device design and analysis in the future.
This book provides comprehensive coverage of device simulation and
analysis for various modem semiconductor devices. It will serve as a
reference for researchers, engineers, and students who require in-depth,
up-to-date information and understanding of semiconductor device physics
and characteristics. The materials of the book are limited to
conventional and mainstream semiconductor devices; photonic devices such
as light- emitting and laser diodes are not included, nor does the book
cover device modeling, device fabrication, and circuit applications.
