MEI Evolution; In-Line, Automated Wet Bench, High Throughput Modular Semiconductor Wet Processing SystemEvolutionHero2013

The MEI Evolution series semiconductor and MEMs automated wet benches are in-line, configurable, automated, modular, linear batch immersion wet process systems made for high throughput at a low cost. They are designed for dry in and dry out batch wafer processing of multiple lots of wafers from 100mm to 300mm, with a Class 1 Environment. Custom configurations combine SECS/GEM interface capabilities, multi step processing, cascade or quick dump rinsing with optional chemical injections, maringoni drying and linear robotic transfer capabilities into a system that is tailored for your specific process needs.  Ultrasonic and Megasonic tanks and baths are available.

Semiconductor, GaAs, solar cell, IC, Medical and MEMS Applications

 

MEI Evolution Auto Wet Bench Systems are suitable for a wide variety of cleaning, etching and stripping applications, including all substrate types used in semiconductor, GaAs, solar cell, IC, Medical and MEMS device manufacturing as well as parts cleaning applications. Configurability, up-time, yield, maintainability and throughput are the hallmarks of an MEI wet processing system.

Dry to Dry, High Throughput, Process Multiple Lots and Recipes Simultaneously

Automated Wet Bench

For production lines with many process steps and complex process sequences, the MEI Evolution series of wet processing systems is a very space and cost-effective solution. The MEI Evolution provides higher throughput, because it is able to process multiple lots and multiple recipes simultaneously, using the sophisticated process controls of MEI’s proprietary IDX Flexware Process Control Software. The Evolution is ideal for processes with hot phosphoric baths and other “lidded” process tanks, as it allows for gravity spiking of multiple chemistries, and provides a fully enclosed environment with HEPA filtration, which can result in better isolation of fumes, higher yield and lower facility exhaust requirements.
IDX logo BMEI’s Advanced Process controls provide the necessary stability of process conditions through closed loop monitoring/control using software recording of all key process variables. The result is a system capable of advanced cleaning and process monitoring capabilities required for critical process steps.
