Chemicals and Materials for Sub-0.100nm IC Manufacturing

Chemicals and materials are used in every processing step in the fabrication of silicon and gallium arsenide integrated circuits. Technological advances in Si and GaAs ICs have resulted in more stringent requirements in the purity and quality of processing chemicals and materials for cleaning, etching, and deposition. As linewidths decrease, the level and size of contaminants in both chemicals and the manufacturing cleanroom become increasingly important as it directly impacts device yield.

This report addresses a number of important factors that will impact the consumption of chemicals and materials for manufacturing ICs with feature sizes <100nm: Technological issues and trends; Purity and particulate requirements; Chemical dispensing practices; Acid reprocessing; Strategic considerations for chemical users; Analysis and forecast of the worldwide chemical market; and trends in usage as devices features decrease.
