Industry Overview

The Lithography Industry: Development and Challenges
GORE® High Flex Cable

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 processes must increase their speeds and output — without sacrificing purity or precision in the process.

GORE High Flex Cables & Assemblies are custom-configured and engineered to meet EUV and DUV needs for lowest particulation — even after continuous flexing > 20 million times. And Gore’s vacuum-compatible cables are always RGA (Residual Gas Analysis) tested, to ensure cleanliness that meets customer specifications.

Product Benefits

GORE® High Flex Cables & Assemblies: Unmatched Qualification

Designed for flexible applications, these finished cables and assemblies provide the unmatched cleanliness an EUV high-vacuum environment demands, along with the extreme durability, flexibility and reliability that both EUV and non-vacuum DUV systems need to meet industry demands for higher yields and productivity. Each High Flex cable solution is custom-designed and co-engineered to your specifications. And we customize without compromise, because we:

  • Incorporate and customize raw materials to provide the low outgassing, low particulation and low contamination that advancing EUV technologies require.
  • Employ IP-protected cleaning processes that meet specifications for both EUV Cleanliness Grade 2 cables and DUV Cleanliness Grade 4 cables.
  • Deliver cables and assemblies with a proven flex life and reliability to withstand repeated multi-million flex cycles.
  • Enable higher data-rate cables with increased transmission speeds, and high and uncompromising signal integrity.
