Cleaning process:
- Process Temperature is about 20 to 25 degrees C.
- Mechanically agitating the cleaning solution or performing the cleaning process within a Sonication, or use of spray system is highly recommended.
- Initially soak wafers or disks in a 1:50 dilution of this solution (5000B: Di-water) for 30 seconds in order to get rid of all loose particles and to increase the lifetime of the actual concentration of your cleaning solution in your cleaning process.
- After the initial step above, expose wafers or disks to SurfPurge 5000B solution in a 1:10 dilution (Lefiq5000B: Di-water) for 40 to 60 seconds.
- Rinse your wafers or disks several times with warm Di-Water to get rid of cleaning solution residue.
- Dry your wafers or disk immediately to eliminate airborne contaminations.
