Removal of organic contamination by the dual effect of ozone and ultraviolet light at two wavelengths
UV Ozone Cleaner
 
※The damage-free dry cleaning method can remove the organic contaminations that stick to the substrates by a photochemical oxidation resolution process.

Product Details


UV Ozone Cleaner Benefits
UV Ozone Cleaner

【Benefits of UV ozone cleaning method】
Easy removal of organic contaminations on the substrate that could not be removed by ultrasonic cleaning alone.
Removal of the organic solvent used in wet cleaning.
Possibility of removing organic contaminations without damaging the substrate surface.
Easier accumulation of the L-B film. (cumulative rate is greatly improved.)
Acailable at a tmospheric pressure. Not require vacuum device.


【Benefits of Filgen's UV ozone cleaner】
 Compact desktop type that saves space.
Automatic gas switching.
By connecting oxygen pipe and nitrogen pipe and setting the flow rate of each gas in advance, the device can perform the following steps automatically.
Oxygen introduction → UV cleaning → Nitrogen introduction (Ozone exhaust)
※Oxygen can increase the efficiency of ozone generation and nitrogen can purge the ozone.
(Straight tube lamp equipped model - UV253V8)
No ozone leak because it has an airtight construction.
The device chamber is an airtight construction that can maintain a pressure of 0.02 MPa.
When connecting to a gas cylinder, the device can perform the following steps automatically without the inflow of external air.
Oxygen introduction → UV cleaning → Nitrogen introduction (ozone exhaust).
※Ozone leak can shorten the life of parts of the device itself and can affect data of chemistry or biological experiments, which can cause serious problem.
(Other models besides of UV253V8)
No ozone leak when it is connected to an ozone decomposing device.
When connecting to a gas cylinder, the device can perform the following steps automatically without the inflow if external air.
Oxygen introduction → UV cleaning → Nitrogen introduction (ozone exhaust).
Optional ozone detection system and door lock mechanism are available to avoid human error that can lead to ozone or UV leak.
(Ozone detection system)
After using an ozone decomposing device or purging with nitrogen, measure the ozone concentration in the cleaning room. The door will be open after confirming the ozone concentration fulfilles the safety standard.
(Door lock mechanism)
The dedicated lock mechanism prevents the door from being opened while the UV lamp is on (during ozone generation).
(Interlocking ozone detection system and door lock mechanism)
By equipping and interlocking the optional ozone detection system and door lock mechanism, the door cannot be opened unless the ozone concentration in the cleaning room fulfills the safery standard.
Depending on the application, two different types of UV lamps (straight tube UV lamps and high density high power grid UV lamps) are available to be selected.
UV Ozone Cleaner UV Ozone Cleaner
For the above two types of low pressure mercury lamps, fused quartz specifications and synthetic quartz specifications are available. Please select according to the application.
It is also possible to replace the lamp later, without changing the other parts of the device.
※The synthetic quartz specification emits 184.9 nm wavelength light much better (about 1.7 times) than the fused quartz specification, which may dramatically improve the cleaning efficiency.
Digital timer with count down function.
Optional Ozone killer (ozone docomposing device) equipping can remove and exhaust the ozone and makes the working environment even safer.
Easy connection because all the nylon tubes and joint connectors are using one-touch joints.
Flexible length of the connection tube, which is made of nylon and can be cut freely.
 

 



UV Ozone Cleaner The principal of UV ozone cleaning

UV Ozone Cleaner

UV ozone cleaning is a photosensitive oxidation process using short wavelength UV light. During this process, organic contaminants such as photoresist, resin, silicon oil, and flux are decomposed by absorbing UV radiation with short wavelength.
Oxygen molecules become ozone at the wavelength of 184.9 nm and ozone is decomposed at a wavelength of 253.7 nm, simultaneously producing reactive oxygen species.
Most of the 253.7 nm UV light is absorbed by hydrocarbons and ozone.
The products of the decomposed contaminants react with the reactive oxygen species and form simpler volatile molecules (ex. CO2 H2O etc.), then detach from the substrate surface.
When both 184.9 nm and 253.7nm wavelengths UV light exist, oxygen atoms continue to be generated and turn into ozone, then the ozone decompose.

UV Ozone Cleaner

Converting the 184.9 nm UV light into energy per mole is 647 KJ/mol.
Converting the 253.7 nm UV light into energy per mole is 472 KJ/mol.
The binding energy of various molecules of organic matter is listed in the right table.
