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 ...

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 ... WebAdvantages and Disadvantages. The Czochralski-technique allows big crystal diameters (state of the art: 18 inch = 46 cm) and – compared to the 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. 10 18 cm -3) and carbon (typ ... shankar director age
