ClassOne expands solstice portfolio for advanced packaging metallization
Flexible, modular platform combines advanced plating, photoresist strip, and wet etch to improve fab efficiency and cost of ownership
ClassOne Technology, a global provider of advanced electroplating and wet processing tools for microelectronics manufacturing, today announced the launch of Solstice® Max, its new, modular 300mm single-wafer platform. Building on the strengths of the proven Solstice S-Series, Solstice Max extends ClassOne’s single-wafer wet processing technology into a new era of scalability, performance, and flexibility for 200mm and 300mm substrates.
Purpose-built for a broad range of wafer-level packaging (WLP) applications, Solstice Max delivers advanced electroplating and surface preparation performance with the ability to process both 200mm and 300mm wafers. Designed from the ground up to deliver low cost of ownership, Solstice Max offers unmatched price-to-performance, process flexibility, and modularity to grow with the user’s production needs. Moreover, the system, while highly sophisticated in functionality, is less complex to operate and service compared to competitive offerings, facilitating its integration into customers’ manufacturing lines.
Modular, Scalable Architecture
Solstice Max is precision-engineered to deliver exceptional on-wafer results and optimal practicality in a single platform. The system supports silicon, glass, thinned, and bonded wafers, with up to 16 process chambers for electrochemical deposition (ECD), solvent, and etch applications.
The platform’s modular design is field-extendible—customers can start with a four-chamber base and expand to as many as 16 chambers as production escalates. Despite its scalability, Solstice Max retains a cleanroom-friendly footprint and accommodates fabs with height restrictions.
“Solstice Max provides a turnkey solution for electroplating, wet processing, solvent strip, and wafer cleans, delivering superior performance and throughput without unnecessary complexity,” said ClassOne Technology CEO Byron Exarcos. “The result is industry-leading ROI and cost of ownership for key applications in advanced packaging, seed and barrier etch, solvent processing, back-end cleans, advanced gold plating, and emerging technologies.”
ClassOne has already received orders for Solstice Max from multiple top-tier customers. Delivery is slated to begin in early 2026.
