This is a single-source treatment of developments in TFT production from international specialists. It interweaves overlapping areas in multiple disciplines pertinent to transistor fabrication and explores the killer application of amorphous silicon transistors in active matrix liquid crystal displays. It evaluates the preparation of polycrystalline silicon TFTs for applications in cameras, video recorders, PDAs, and cell phones. The authors provide an introduction to the technology, a historical overview of its development, and a discussion of the characteristics and applications of TFT display technology. This treatment will be useful to students, designers, and engineers who require both the background information and knowledge of the applications of this technology.
