Caustic Etch

Caustic etch and acid neutralizer system for high throughput requirements of the solar cell industry. A special fume-exhaust design helps contain the high volume of chemical vapor which escapes from the enormous surface area presented by each wafer batch. Full system automation and enclosed front access area ensures safe operation and consistent results. The system features a high-efficiency dump-rinser for rough rinsing, followed by a recirculating running rinse to ensure purity, and reduce water residue to a minimum, prior to evaporative drying.

In cell production, manufacturing costs per kW produced is always at the bottom line. Interlab’s hot water DI regeneration system allows thorough rinsing at very low running cost, possibly saving thousands of gallons of DI water per day, while ensuring higher yields by uniquely preparing substrates for stain-free evaporative drying. Likewise, our patented drying chamber minimizes energy and maintenance costs by continuously recirculating the airflow through the HEPA-filter and process chamber.

Note also that our rinsing and drying equipment can be configured as stand-alone units to conserve resources and/or improve yields for existing wet process systems.
