Dopant impurity atoms such as boron or phosphorus can be added to the molten silicon in precise amounts to dope the silicon, thus changing it into p-type or n-type silicon, with different electronic properties. A precisely oriented rod-mounted seed crystal is dipped into the molten silicon. The seed crystal's rod is slowly pulled up…
WebJan 17, 2024 · The V-Ingot sample shows spot-like Fe-B precipitates of diameters in the range 0.5-1.5 μm distributed in the matrix, whereas in the H-Ingot sample, these precipitates are more elongated and aligned parallel to the radial direction (RD) of the original cylindrical ingot. The width of these precipitates is also 0.5-1.5 μm. WebFeb 12, 2013 · The ingots’ macrostructure is free of both nonaxial and axial segregation zones.
