High Pressure Rinsing (HPR)

• HPR from SPEC (US).• HP pump (140 bar, 1.1 m3/h)

@ 3 stages to prevent vibration.• Rinsing cabinet with top wand

design (needed in SM18).• Cabinet should have a pass

trough design => load/unload fromdifferent class cleanrooms.

• Drying of the cavity by blowing hot N2.

• Rinsing nozzle to be designed.

ISO 7 ISO 4

Air Box

Built in 1991.

Goals :• Increase cleanliness.• Create a rinsing room.• Get ride of the Air Box to gain space.

ISO 14644-1 FS 2094 105 1007 10 000

Cleanroom layout (Updated)

07/12/2012

• Update should be done by Daldrop, initial builder of the facility.• Extension of the rinsing room.• Creation of a preparing room outside of the facility.

Cleanroom layout (Updated)

Refurbishment of the filtering system with Fan Filter Unit (FFU).

Rinsing room extended to 4.5m high to held the HPR.

Preparing room based on softwall design.

Ultra Pure Water production

07/12/2012

•Pre-design of the installation, done by Veolia France•Production capacity of 1 m3/h.•UV lamp (185 nm) to prevent bacteria growing and decrease Total Organic Carbone (TOC):

CXHYOZ -> CO2 + H20 -> H2CO3 -> H+ + HCO3- HCO3- absorbed by polishing resin.

•Need to cool down the recirculation water due to the temperature in SM18.

Optical Inspection (SPL01 Cu)

• Use to perform the functional test of the bench and get experience.

• First picture of an equator welding.

• Easier illumination on copper.

Optical Inspection, what’s next?

• Get a code to automate the inspection:– Autofocus– Step motion– Auto illumination

• Get a code to automate the analysis:– Colour correction– Image assembly– Contour detection to find defects

Conclusion

• Contracts should be signed for:– Cleanroom – High Pressure Rinsing– Ultra Pure Water

by the end of the year 2012.• Build a rinsing nozzle.• Develop a code to automate the optical bench

and gain experience with SPL01 Nb.• Optical Inspection is waiting for a quench.
