Overall rating: (N/A)
|
Tends furnaces that diffuse chemicals into semiconductor waefr
surface to alter electrical characteristics of wafer or to
protect wafer surfaces: Places semiconductor wafers in
containers, such as boat or cassette, using vacuum wand or
tweezers.
Places loaded cotnainer on furnace loader, such as
conveyor, track, sled, or tube. Pushes button to advacne wafer
containers into furnace or pushes wafer container into furnace
