Industry Overview
The Lithography Industry: Development and Challenges

The growing demand for semiconductors — driven by 5G, the Cloud and AI — will only intensify as ever-more devices and technologies are integrated into homes, workplaces and transportation systems. To meet this accelerating demand, fabs using EUV and DUV lithography must increase their speeds and output — without sacrificing purity or precision in the process.
The properties and performance characteristics of GORE® Ultraclean Static Round Cables & Assemblies align with the industry's dual goals: greater precision and cleanliness to support more extreme miniaturization, and greater reliability to support demands for higher yield, quality and speed.

Product Benefits
GORE® Ultraclean Static Round Cables & Assemblies: Unmatched Cleanliness
Designed for static applications, our Cleanliness Grade 1 cables and assemblies meet the most extreme requirements for high-vacuum environments. Gore’s IP-protected cleaning processes enable us to produce high-purity cables and assemblies that are approved for use in the innermost parts of the most advanced EUV systems. Along with unmatched cleanliness, these custom-engineered static round cables provide unmatched performance, because our materials expertise enables us to:
- Achieve higher data rates, with greater signal integrity over longer distances, and precise, reliable terminations.
- Incorporate low-contamination, low-outgassing fluoropolymers such as ePTFE (expanded polytetrafluoroethylene) material, and we can further trim outgassing levels to customer requirements.
