In modern semiconductor R&D, reproducible and contamination-free wet processes are essential. A fully integrated wet processing platform has been implemented, combining four complementary wet benches into a single scalable cleanroom infrastructure.
The system is designed for ISO 5 environments and supports research, development, and pilot-scale processing of delicate semiconductor substrates.
System Architecture: Four Wet Benches, One Process Ecosystem
