Cleaning Systems


Bench top UV-Ozone Cleaning System
The UV-2 is a compact, high-performance, bench top, UV-Ozone Cleaning system. The UV-2 is modular in design and can be configured specifically, upon order, for a number of cleaning, stripping or UV-curing applications. This system is drawer loaded and uses patented technology to uniformly distribute ozone and UV light over the surface of wafers or other substrates. The system employs a programmable logic controller and safety interlocks to protect the operator from hazardous exposure to process ozone and UV light.
This easy to operate system uses a unique combination of ultraviolet radiation, ozone and heat to gently, yet effectively, remove organic materials from a variety of substrates including silicon, gallium arsenide (GaAs), Sapphire, metals, ceramics, quartz and glass.
The versatile UV-2 is well-suited for a variety of applications such as substrate cleaning, photoresist descumming, improving wettability, and UV curing. By operating at atmospheric pressure, the UV-2 eliminates the need for a cumbersome, high-maintenance vacuum system. This system is CE marked and UL certified.


Main Unit: 610(W) x 572(D) x 426(H) mm
