The science behind the manufacturing and inspection of etched silicon wafers for computer processors requires the utmost of precision. To meet that precision, the optical components that make up the photolithography stepper and inspection tools must be extremely precise. Precision Optical is continually “pushing the envelope” to meet the requirements of this exponentially growing industry. The demand for the line widths of wafer patterns continues to get deeper into the UV in order to make processers smaller and more powerful. The quality of the stepper and inspection tools that image and inspect the wafer patterns must adapt to meet this demand. Precision Optical fully supports the semi-conductor industry, and understands that optical materials, optical coatings, and optical metrology must also adapt to the ever-growing needs of the market.
