Flat zone wafer

Float-zone silicon is very pure silicon obtained by vertical zone melting. The process was developed at Bell Labs by Henry Theuerer in 1955 as a modification of a method developed by William Gardner Pfann for germanium. In the vertical configuration molten silicon has sufficient surface tension to keep the charge from separating. The major advantages is crucibleless growth that prevents conta… WebApr 6, 2024 · ⑤ Notch: Wafers with a notch have recently become available instead of a flat zone.
