WebSep 5, 2024 · Float zone FZ crystal growth. Last Updated on Mon, 05 Sep 2024 Plasma Etching. If high purity or oxygen-free silicon is needed, float zone (FZ) crystal growth is used. In the FZ-method, a polysilicon ingot is placed on top of a single-crystal seed. The polycrystalline ingot is heated externally by an RF coil, which locally melts the ingot. WebTo overcome these problems, Float Zone (FZ) wafers may be used 1. In this process, a molten region is slowly passed along a rod or bar of silicon. Impurities in the molten region tend to stay in the molten region rather than be incorporated into the solidified region, thus allowing a very pure single crystal region to be left after the molten ...

WebThe Czochralski Method. The Czochralski method of growing silicon crystals is the cheapest and most common way of making silicon wafers. However, it tends to produce impurities in the silicon, which have a negative effect on the efficiency of solar panels. For higher purity Float Zone (FZ) wafers are used. Web6.1.2 Silicon Crystal Growth and Wafer Production. We now have hyperpure poly- Si, already doped to the desired level, and the next step must be to convert it to a single crystal. There are essentially two methods for crystal growth used in this case: Czochralski or crucible grown crystals ( CZ crystals). Float zone or FZ crystals.

WebAs a result, in order to get the pure silicon that is required for silicon wafers, a variety of silicon growing methods is used. There are two extremely popular and advantageous single-crystal growth methods that are able to achieve the material requirements that are needed for wafers: float zone (FZ) and Czochralski growth (CZ). Each of these ...
