Ultra Violet Ozone
Cleaning Systems
- Ultra clean
surfaces
- Room temperature
process
- Fast - less than
ten minutes for many applications
- Easy Processing
- Modest initial
price and minimal operating cost
UV/Ozone cleaning
process provides a simple inexpensive, fast method of obtaining
ultra-clean surfaces free of organic contaminants on most inorganic
substances, such as quartz, silicon, gold, nickel, aluminum, gallium
arsenide, alumina, etc. The process is ideal when thin film deposition
with excellent adhesion to the substrate is required. Ultra-clean
surfaces can easily be achieved by UV/Ozone processing in one to
several minutes after the substrate has been cleaned by conventional
techniques.
UV/Ozone Cleaning
Removes Traces of:
Skin oil, silicone
oil and grease, solder flux, residual photoresist, condensed adhesive
volatiles, carbon traces.
How Clean is
"ultra" clean?
Contact angle
measurements of 4-5 degrees. Miniscule peakes when measured with AES
and ESCA. With steam test, there are uniform rainbow-like fringes
during condensation and evaporation. Often, cleaning of critical
surfaces prior to other processing steps is considered finished after
the usual scrubbing and ultrasoneration steps. Ultra-violet/ozone
cleaning adds a new dimension to cleaning... a valuable new dimension
that can prove itself in dollars and cents in improved performance and
reliability in applications where UV/Ozone can be used after the
standard cleaning operation.
