Semicon equipment lifetime

Semicon and quantum
5 June 2024

Advanced lithography equipment operates under challenging conditions. From extreme ultraviolet (EUV) photons, gas flows, plasma and high vacuums to particles and potential degradation. In order to ensure lithography equipment continues its precision work for the longest possible time, the TNO Semicon equipment lifetime research group offers bespoke lifetime studies and in-depth insight into equipment lifetime management.

Supporting industry innovation

Chip manufacturers are constantly innovating the materials and processes they use to advance their technology. TNO offers a Reticle Stack Assessment to assess the compatibility of new reticle materials with EUV lithography equipment. This fully independent and customised testing programme can recreate lifetime conditions at a highly accelerated pace. Of course, TNO protects all proprietary information about lithography materials and processes in strictest confidence.

TNO is ASML’s only offical partner for the Reticle Stack Assessment. After thorough investigation of the reticles (or other materials) sent for testing, TNO offers a complete report of material behaviour under EUV scanner-like conditions. When the reticle passes the assessment, ASML provides a waiver that enables chip manufacturers to use the reticle with the new materials in their EUV scanner.

Exploring beyond state-of-the-art

For more than 25 years, TNO has partnered with ASML and Carl Zeiss GmbH to test advancements in DUV and EUV lithography technology. From novel materials to new designs, we work closely with our partners to better understand how specific materials and components can affect productivity and yield and to further extend the lifetime of DUV and EUV lithography equipment. Our unique, state-of-the-art facilities offer a thorough perspective on how improvements and innovations impact the machine’s operability and longevity. We provide in-depth reporting that makes the impact of these innovations clear and tangible, and expert advice on the best approach.

Facilities for every need

TNO manages more than 20 different experimental facilities for testing and analysing lithography components. We are constantly improving our state-of-the-art EBL2 facility for EUV testing. We also offer unique plasma testing facilities, as well as (sub-)surface analysis afterwards. In many of these cases, we can ensure that a sample stays in vacuum between exposure and analysis. But perhaps our greatest added value is the expertise and knowledge we offer, which combines your test’s results with our 25 years of experience in equipment lifetime management. Our thorough investigations offer insights on a fundamental level, and precisely indicate the impact of materials on your machine.

Partnering for longevity

Manufacturers looking for assurance that their lithography machines will continue to run as needed for their entire expected lifetime turn to TNO for testing and advice. Our unique facilities and extensive knowledge in this domain are unmatched in the industry, and our independent way of working offers confidence and trust.

Collaboration for advancement

TNO is actively engaged in a number of EU-funded research projects concerning advancements in EUV lithography and other related technologies. Although our work for clients is strictly confidential, we have published papers on our research. Please find some of these publications below.
