Transform Your Manual Wet Bench into a Smart Yield-Protected System

If your FAB is still operating manual (hand-dip) wet benches, you already know the risk — wafer yield loss due to dipping wafers into the wrong chemical bath or incorrect etch time.

EIMWA – Manual Wet Bench Automation by einnosys is a powerful, non-invasive solution designed to eliminate human errors — without replacing or upgrading your current wet bench — saving you hundreds of thousands of dollars in upgrade and replacement costs.

Through our system of barcode scanner, mobile device, and required software, you can ensure wafers are always processed in the right bath for exactly the duration of etch time.

Why EIMWA

Improve Yield Without Replacing Your Wet Bench

Unlike a full Manual to Automatic Wet Bench Upgrade, EIMWA works with your existing equipment. There is no need for costly hardware replacement or long requalification cycles. Our Semiconductor Wet Bench Automation approach focuses on process control, wafer tracking, and MES integration — not mechanical modification.
