This book introduces radical-reaction-based semiconductor manufacturing technologies that overcome the limitations of the existing molecule-reaction-based technologies. It systematically details the procedures and underlying concepts involved along with other wet process technologies and applications. Following an introduction to semiconductor surface chemical electronics, expert contributors discuss the principles and technology of high-performance wet cleaning, etching technologies and processes, antistatic technology, and process and safety technologies including waste reclamation, chemical composition control, and ultrapure water and liquid chemical supply systems and materials.
