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.
Thermal oxide wafers are used when a silicon substrate needs a high-quality silicon dioxide layer for insulation, masking, surface protection, dielectric control, or process development. The value of a thermal oxide wafer comes from the oxide layer grown on the silicon surface, not only from the base wafer.
