The Macroeconomics of 450mm Wafers | SEMI

The minimum silicon cost with 200mm diameter wafers is about $2 per square inch, resulting in a maximum cost per wafer of $100.. The minimum silicon cost reached with 300mm diameter wafers is about $3 per square inch, resulting in a maximum cost per wafer to of $400. Thus, for every succeeding increase in wafer size, there is approximately a 1.4 times increase in costs of manufacturing.

Silicon Ingot Production - MicroChemicals

Float-zone technique described in the following section – lower production cost per wafer. One disadvantage of the Czochralski technique is impurities such as oxygen (typ. 1018 cm-3), carbon (typ. 1017 cm-3) from the quartz and graphite crucible which lower the minority carrier diff usion length in the fi nished silicon wafer.

The ingot is then given a notch or flat to indicate its orientation, depending on the wafer diameter, customer specifications, or SEMI Standards. Once it has passed a number of inspections, the ingot is sliced into wafers. SVM can currently produce 200mm and 300mm silicon ingot, as well as custom diameters between 285mm and 440mm.
