W200 Wet Bench for Semiconductors

Automated wet bench cleaning developed specifically for the semiconductor industry: reliable, repeatable cleaning and preparation of wafers and sensitive components, certified to SEMI standards with SECS-GEM integration.

The W200 is a wet bench tool designed to meet the stringent requirements of semiconductor manufacturing, providing a reliable and cost-effective solution for the cleaning and preparation of wafers and other sensitive components during production. Developed on the proven 200-series platform specifically for the semiconductor industry, it is certified to SEMI standards and integrates with the fab host through the SECS-GEM protocol.

Closed-loop cleanliness

A closed-loop cleaning system with integrated filtration minimises contamination risk, and batches are indexed through the process by a two-axis pick-and-place servo transporter with full process flexibility: any stage, in any order, with any combination of processes loaded in sequence. A choice of ultrasonic cleaning and rinsing frequencies matches the process to the substrate, the final rinse draws on integrated pure water generation, and full batch tracking and datalogging record every load for traceability.

Control, software and support

The system is controlled by a Beckhoff PLC with full motion control integration, driven from a touchscreen interface running Unitech Shyre software optimised for simple operation. Complete diagnostic coverage reports any technical problem to the operator, auto-start brings the line up and down to a seven-day schedule, and sleep mode cuts power consumption between runs. An always-on secure VPN connection supports remote diagnostics, process support and software updates, and SECS-GEM integration brings control, monitoring and reporting into the fab host.

Options

Applications

Wafer cleaning, tooling cleaning and semiconductor component cleaning in production environments. Its sister machine for precision optics and wider industrial cleaning is the PC200 precision cleaning system.
