Hong Kong Specialty Gases offers the broadest line of semiconductor grade wet chemicals in the industry. With purities that extend to the parts-per-trillion level, these high-quality acids, etchants, solvents, cleaning formulations and other process chemicals are used by semiconductor and wafer fabs the world over.
All of our suppliers are basic manufacturers, they go far beyond simply repackaging as other companies' chemicals. By vertically integrating sulfuric acid production, nitric acid distillation and hydrofluoric acid generation, for example, they control the entire production process from assuring raw material quality to final packaging. This allows us to evaluate and enhance all processes continuously, so our products can help minimize defects and improve yields.
Our Process Capable Specification Program is a good example of how we improve quality. This program combines the basic manufacturing strengths with sophisticated statistical methods to enhance purity and narrow product variability. It allows us to set notification limits well below our customers' specifications, so they learn of even relatively minor shifts in product properties that could affect them.
