ACM Research Unveils the Ultra Lith BK System
At SEMICON EUROPA, ACM Research, Inc. (NASDAQ: ACMR) introduced its first Ultra Lith Baker system, also known as the Ultra Lith BK. This innovative tool is specifically designed to tackle challenging hurdles in advanced lithography, aiming to improve semiconductor and advanced packaging processes.
Addressing Industry Challenges
The Ultra Lith BK is equipped with cutting-edge technology aimed at mitigating key challenges like non-uniform processing and temperature fluctuations, which are critical for maintaining the consistency and quality of semiconductor manufacturing. As device sizes continue to scale down, reliable lithography becomes increasingly essential for optimal yield and pattern accuracy.
Exceptional UV Curing Performance
A standout feature of the Ultra Lith BK is its advanced UV curing system, ensuring an impressive UV intensity uniformity of ±5%. This capability guarantees that photoresist hardening occurs consistently across the entire wafer surface, reducing variability. The tool supports various exposure modes, including line-scan, rotary, and hybrid, catering to diverse process requirements and enhancing operational flexibility.
Enhanced Thermal Management
In addition to UV curing, the Ultra Lith BK includes sophisticated thermal management systems that promise temperature uniformity within ±0.1°C. This precision is crucial to minimize critical dimension (CD) variations, overlay errors, and any pattern distortions that could adversely affect production yield and long-term reliability.
Dr. David Wang: Insights on the Ultra Lith BK
Dr. David Wang, President and CEO of ACM, expressed enthusiasm regarding the Ultra Lith BK's capabilities, noting its significance for their customers. "The introduction of the Ultra Lith BK positions us strongly within the display panel segment, which demands high-volume production and unparalleled performance from processing equipment. Our system’s configurable architecture, combined with exceptional uniformity, assists manufacturers in scaling their production effectively for future technological advancements,” he stated.
Flexible Configuration and Performance
The Ultra Lith BK incorporates advanced design features with six cold plates, allowing an adaptable setup that can include up to 32 hotplates along with two UV curing systems. This flexibility permits manufacturers to tailor the system based on various process recipes and photoresist needs.
Hotplate Options
Users can select between two categories of hotplates for diverse operational requirements:
- The high-flow hotplate achieves a top temperature of 250°C with a uniformity of less than 0.2%.
- The low-flow hotplate operates efficiently at temperatures reaching 180°C, with a temperature uniformity of ? 0.08%, providing exceptional industry performance.
