A wafer COA should include the material identity, wafer specifications, measured inspection results, test method references, batch information, packing details, and approval record. It should not be a simple delivery note.
Silicon wafer lead time is affected by material type, diameter, resistivity range, dopant, crystal orientation, thickness, surface finish, polishing route, cleaning requirement, coating process, inspection level, quantity, and packing. Delivery planning should not be based on wafer name alone.
Dummy silicon wafers are used to protect production wafers, stabilize equipment conditions, test process recipes, and reduce the cost of trial runs. They are not final device wafers, but they play an important role in semiconductor manufacturing, laboratory testing, equipment calibration, cleaning cycles, oxidation, deposition, lithography setup, and handling verification.
