EV Group Unveils EVG120 Resist Processing System

Why It Matters

The EVG120 delivers higher throughput and tighter process control in a compact form, helping semiconductor manufacturers accelerate time‑to‑market while reducing cost of ownership. Its flexible architecture addresses the growing demand for diverse resist materials and substrate sizes across emerging device segments.

Key Takeaways

• 40% capacity increase on 200 mm platform
• Footprint reduced over 20% while adding modules
• In‑situ thickness measurement improves yield
• Wafer edge exposure enhances edge uniformity
• Supports SMIF loadports for cleaner handling

Pulse Analysis

The semiconductor lithography ecosystem is increasingly pressured to handle a broader mix of device architectures, from advanced packaging to photonics and MEMS. Traditional resist coating tools, often large and single‑purpose, struggle to keep pace with the rapid material diversification and tighter cycle times demanded by R&D and volume production. EV Group’s EVG120 arrives as a response to this shift, offering a versatile, compact platform that can process substrates ranging from 2 in. wafers to 200 mm plates, accommodating thin, thick, positive, negative and specialty resists in a single footprint.

At the heart of the EVG120 are several technical upgrades that translate directly into productivity gains. A redesigned architecture integrates up to two wet‑processing modules and fourteen bake/chill plates, delivering a 40% throughput uplift while the system’s overall footprint shrinks by more than 20%, freeing valuable clean‑room space. New functions such as wafer‑edge exposure improve edge uniformity, and real‑time resist thickness metrology (50 nm‑50 µm range) enables immediate process adjustments, boosting yield and reducing scrap. The high‑viscosity dispense system, with closed‑loop feedback, ensures precise coating of thick photoresists, while SMIF loadport compatibility streamlines material handling and contamination control.

For manufacturers, the EVG120’s blend of flexibility, efficiency and lower energy consumption (standby mode meeting SEMI E167 standards) represents a strategic asset in a competitive market. Its ability to serve both R&D pilots and high‑volume production lines shortens the path from prototype to market launch, particularly in fast‑growing sectors like power devices and wafer probe cards. As the industry leans toward heterogeneous integration and miniaturization, tools that combine multi‑process capability with a reduced cost of ownership will be pivotal, positioning EV Group’s new system as a compelling choice for forward‑looking fabs.
