High Purity Fused Silica

High Purity Fused Silica

Our High Purity Fused Silica glass is known throughout
the semiconductor industry for its consistent, repeatable performance.

HPFS® Fused Silica

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 a minimum of 25years 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.

HPFS® Laser Resistance

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. With the drive to smaller and smaller structures, the semiconductor industry continues its quest for better and better optical systems, and this in turn drives the requirements for the optical materials.

Commitment to Quality

ISO9001 and ISO14001 Certified
