A
carrier system wich allowed handling of 20 glass substrates at a time.
This system was rotational symmetric to allow spinndrying. This is an
efficient method to dry the glass surace without getting dry
stains. Even thow the water are purified microscopic amount of
impurities still could contaminate the surface if improper drying
was used.
With this system any diameter of the glass could be handed by
changing the side walls of the carrier. All stainless stel and PTFE
allowed for agressive chemicals and high temperature drying after
spin drying. Still after a spin drying sequence a monolayer of
water molecules has to be removed in an clean room oven.
The spin dryer was constructed to allow the carrier to
rotate without vibrations. A shower of purified water is
sprayed prior the high speed spinnig.
