" It is easier to place most of the manufactuing process in a vacuum and eliminate the dust particles. {Hint: dust cannot float in a vacuum to land on the wafers, but drops like a rock to the floor.} " According to my physics class in high school a perfect vacuum cannot be created and there will always be some air left over... Concerning issue's with damage to chips by vaporization: 1. First create a vacuum. 2. Then convert any floating(?)/remaining dust particles to energy. 3. Then place wafers inside it and start vacuuming. Alternatively plan: Slowly turn dust into energy to prevent nuclear explosion ;) :) Another crazy idea would be to use water and produce the chip in water... Somehow purifieing water and maybe water better than air ? But I doubt it ;) I just had another idea: 1. First create a vacuum as good as possible. 2. Then highly charge the surroundings of the vacuum with static electricity. Hopefully this will attract all remaining floating dust particles. 3. Perhaps keep it like that... and start producing the chip. 4. Otherwise if the static charge is to be disabled, first vaporize the dust particles on the side or wipe them off ?!? Bye, Skybuck.

None that would keep a dust particle lofted though you ZERO common sense dumbfucktard! |
