High Purity Polycrystalline Silicon Growth and Characterization

WebThe floating zone (FZ) technique is a crucible-free crystal growth method. In FZ growth, the molten zone is kept between two vertical solid rods by its own surface tension ( Figure 17 … WebFloat 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.
