Bridgman-Stockbarger technique

The Bridgman-Stockbarger technique is illustrated in Figure 29.8. The powdered charge is melted in a crucible, which is often a refractory metal Pt, Ir, or Mo. This technique necessitates that the melt does not significantly react with the crucible. The furnace is designed such that there is a sharp drop in temperature just below the bottom tip of the crucible in its initial position.

The next step is to produce nearly perfect single-crystal boules of silicon from the ultrapure polycrystalline silicon. Many techniques have been developed to accomplish this, and they all rely on a similar set of concepts that describe the transport process, thermodynamically controlled solubility, and kinetics [8]. Three important methods are the vertical Bridgman-Stockbarger, Czochralski, and floating zone processes, fully described in Fundamentals of Crystal Growth by Rosenberger [9].
