Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically the metal–oxide–semiconductor (MOS) devices used in the integrated circuit (IC) chips that are present in everyday electrical and electronic devices. Maintaining optimal conditions throughout the production process is the key to providing semiconductor devices with consistently high yield rates and quality levels. The semiconductor manufacturing process is like process manufacturing in that most of what happens is adding value to the flow of materials through the process. Search for more papers by this author.
