CHAPTER 1 INTRODUCTION MIT

Despite the many advantages of copper, copper patterning requires an entirely new manufacturing platform, damascene technique. As described earlier, the copper damascene technique circumvents metal etching, using the CMP process to form copper wiring inside the trenched oxide. The CMP process must be integrated horizontally and vertically to ...
