Evolution Wet Processing System

High Throughput, Modular, Dry to Dry, Multiple Lots, Multiple Recipes & Advanced Scheduler

The Evolution Wet Processing System is a Full-Auto Linear Wet Bench. It’s designed to be highly configurable, fully-automated, and modular. As a batch immersion wet process system, the Evolution is made for high throughput at the lowest cost. They are designed for dry in and dry out with multiple lot batch processing capabilities  for wafer sizes 100mm to 300mm, within it’s own Class 1 Environment. Running under IDX Flexware control, the Evolution is one of the most advanced wet processing systems on the market. With multiple advanced features and capabilities, to include multi-step processing, specialized process tanks, Ultrasonic and Megasonic tanks, cascade or quick dump rinsing, chemical injection and spiking, Genesis X marangoni drying, robust, reliable robot transfer and SECS/GEM compliant host capabilities. The Evolution is custom tailored to meet your specific process needs.

Highly configurable Modular Design

For production lines with multiple process steps and complex process sequences, the MEI Evolution Wet-Processing systems is a very space and cost-effective solution. The MEI Evolution provides a higher throughput, because it is capable to process multiple lots and multiple recipes simultaneously with MEI’s proprietary “Scheduler” application within IDX Flexware. The Evolution is ideal for processes with hot phosphoric baths and other “lidded” process tanks, as it allows for gravity spiking of multiple chemistry, and provides a fully enclosed environment with HEPA filtration.

MEI’s IDX Flexware Process control provides the necessary stability and control of all process conditions through closed loop monitoring/control while logging all key process variables. The result is a reliable, repeatable system capable of advanced processes monitoring capabilities required for critical process steps.
