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… Witryna1 mar 2024 · The compelling evidence attributes the novel coalescence of in-gaps states toward the ZBP to the change in the nature of the magnetic impurity-induced defect state from the vortex-free YSR...

Czochralski Method - an overview ScienceDirect Topics
WitrynaFloat Zone Silicon. Float zone silicon is extremely pure silicon that is obtained by vertical zone melting. This method produces the high-purity alternative to Czochralski silicon. However, one negative of float zone silicon is that their wafers are generally not greater than 150mm due to the surface tension limitations during growth. WitrynaThe Czochralski (Cz) method is the most important method for the production of bulk single crystals of a wide range of electronic and optical materials ( Figure 2 ). At the beginning of the process, the feed material is put into a cylindrically shaped crucible and melted by resistance or radio-frequency heaters. Witrynaof introducing impurity atoms into a semiconductor wafer by ion implantation. The purpose of semiconductor doping is to define the number and the type of free charges in a crystal region that can be moved by applying an external voltage. The electrical properties of a doped semiconductor can either be developmental and family life cycle theory
