Dedication to technology leadership and world-class metrology capabilities play a major role in Corning’s ability to produce leading edge materials. Corning is committed to ensuring that its customers are provided qualified, authentic products.

Corning has decades of measurement experience and provides a certificate of compliance for each sale of product to verify the authenticity of our HPFS® Fused Silica Materials.

Fused Silica is offered in many different grades to support various product applications. Glass codes 7980, 7979, and 8655 are high purity non-crystalline silica glasses with excellent optical qualities.

Product characteristics include extraordinary low refractive index variations leading to state-of-the-art homogeneity values, lowest birefringence values, large size capabilities, exceptional transmittance from the deep ultraviolet through the infrared region, and an ultra-low thermal expansion coefficient; all of which are critical to our customers’ demanding needs.

Our strength is in material chemistry and development, and we are committed to be the technology leader for next generation steppers by continuing our development of new materials. Optical materials are at the heart of the semiconductor industry. Microlithography projects a pattern from a photomask through an optical system to create IC chips using ultraviolet laser light.

Optical inspection microscopes provide test capabilities for both masks and wafers at several different stages of the printing process.
