Microstructure Control of Columnar-Grained Silicon Substrate Solidified from Silicon Melts Using Gas Pressure

<div>Schematic diagram of the structural formations of the liquid-solid interface depending on the difference between the temperature of the mold (<i>T1</i>) and the temperature of the dummy bar (<i>T2</i>) in the solidification zone of growth part: (a)<i> T1</i> ≤<i> T2</i> and (b)<i> T1</i> ≫<i> T2</i>. The arrows indicate the pulling directions. L and S represent liquids and solids, respectively.</div>
