physical and chemical processes to be performed on a semiconductor
substrate. In general, these processes fall into three categories:
film deposition, patterning, and semiconductor doping. Films of
both conductors and insulators are used to connect and isolate
transistors and their components.
By creating structures of these various components millions of
transistors can be built and wired together to form the complex
circuitry of modern microelectronic devices. Fundamental to all of
these processes is lithography, ie, the formation of
three-dimensional relief images on the substrate for subsequent
transfer of the pattern to the substrate.
This book presents a complete theoretical and practical
treatment of the topic of lithography for both students and
researchers. It comprises ten detailed chapters plus three
appendices with problems provided at the end of each chapter.
