SUSS Expands Photomask Portfolio with Next-Generation ASC9500 Mid-End Cleaner

     
  Strategic expansion of the Photomask Solutions portfolio to address evolving requirements in mature-node manufacturing Next-generation extendable cleaning platform building on the proven ASC5500, representing a major platform renewal Depending on configuration, the ASC9500 Mid-End Cleaner supports technology nodes ranging from 38 to 90 nanometers Introduction of acid-free in-situ UV cleaning technology reduces chemical consumption and operating costs Multiple customer requirements have already been identified, and manufacturing of the ASC9500 has begun   Garching, Germany, November 9, 2026 – SUSS MicroTec SE (MDAX/TecDAX: SMHN), a leading supplier of equipment and process solutions for the semiconductor industry, today introduces the ASC9500 photomask cleaning system. With the new system, SUSS brings proven cleaning technologies to mature-node photomask manufacturing, combining production capability with the flexibility to address diverse and evolving process requirements. The extendable ASC9500 platform strengthens SUSS' photomask cleaning portfolio and expands its addressable market. Growing Demand for High-Performance Solutions for Mature Technology Nodes Demand for semiconductors based on mature technology nodes remains strong. These proven manufacturing processes are reliable, widely available, and economically attractive. They are used in numerous applications, including automotive, industrial electronics, power semiconductors, and increasingly advanced packaging applications. Driven by AI, increasingly complex semiconductor devices, and heterogeneous integration, semiconductor manufacturing is becoming more diverse. This development creates demand not only for leading-edge technologies but also for greater manufacturing capacity and process flexibility at mature nodes. As production volumes increase, demand for photomasks and associated process solutions continues to grow. Since photomasks are repeatedly used throughout semiconductor manufacturing, effective cleaning is essential to maintaining yield, process stability, and manufacturing efficiency. At the same time, manufacturers face rising requirements for cleaning performance, yield, and cost efficiency. A Next-Generation, Extendable Platform for Evolving Customer Requirements

Building on the proven ASC5500 photomask cleaning system, the ASC9500 represents a comprehensive platform renewal and introduces an extendable architecture designed to support future customer needs. The new generation offers significantly expanded capabilities and integrates advanced features that were previously available only in SUSS' high-end cleaning systems. It also provides a next-generation option for customers using the manual HMx cleaning systems. Depending on configuration, the ASC9500 addresses technology nodes between 38 and 90 nanometers. Its extendable design allows customers to adapt the system to changing process requirements while maintaining cost-efficient operation. Sustainable and Cost-Efficient Operation

A key feature of the ASC9500 is its integrated acid-free in-situ UV cleaning technology. This technology significantly reduces chemical consumption, lowering operating costs while supporting customers' sustainability goals. The result is a highly efficient cleaning solution that combines advanced process performance with a reduced environmental footprint. Customer Demand and Market Opportunity SUSS has already identified requirements from multiple customers, and manufacturing of the ASC9500 has begun. The introduction of the ASC9500 broadens the company's footprint in semiconductor manufacturing application while leveraging technological expertise developed through its leadership position in advanced photomask cleaning applications. By extending proven high-end cleaning technologies to a broader customer base, SUSS is addressing an attractive market opportunity while enabling customers to achieve advanced cleaning performance at a competitive cost of ownership. "The semiconductor market is becoming increasingly diverse, and mature-node manufacturing requires both greater production capacity and process flexibility. With the ASC9500, we are renewing a well-proven cleaning platform and introducing an extendable solution designed to address evolving customer requirements. We already see demand from multiple customers and have started manufacturing. The ASC9500 reinforces our commitment to supporting a broad range of photomask applications and strengthens our position in the photomask cleaning market," said Yuta Nagai, Senior Vice President Photomask Solutions at SUSS. The ASx9500 Platform for End-to-End Photomask Processing Together with the APB9500 post-exposure bake solution, which is already widely used in the production of photolithographic masks, the ASC9500 expands SUSS' ASx9500 platform into a comprehensive offering for photomask processing. SUSS is the global market leader in cleaning photomasks for the most advanced technology nodes in semiconductor manufacturing and is now bringing this cleaning expertise to a broader range of semiconductor manufacturing applications with a precisely tailored solution.
