I work as technician in a Singapore semiconductor factory. Here I share my working life as technician.
The product -wafers need to transfer from the cassette to the machine , and 1 by 1 mounted onto wafer holder and transfer into chambers to do the deposition.
This is the wafer holder housing, as you can see 2 ceramic pins at the side to hold the assembly to machine seal ring
This is the clamp ring, wafer sit on this piece.
The full set of PM kitting for wafer holder preventive maintenance (PM): 5S is always emphasized in the work place.
the wafer holder assembly area, graphite stone for flatness monitor and checking.
As it's critical for the wafer holder assembly work to be done properly. Most of the time need to dedicate 1 person to fully concentrate the work and record down the part number and serial number for tracking purpose.
:) many info ya , keep it up bro, appreciate your works , do share more with us
