UNIDIRECTIONAL SOLIDIFIED SILICON INGOT AND MANUFACTURING METHOD THEREOF, SILICON PLATE, SUBSTRATE FOR SOLAR CELL AND TARGET BASE MATERIAL FOR SPUTTERING

摘要

PROBLEM TO BE SOLVED: To reduce working cost and obtain high yield by weight in a unidirectional solidified silicon ingot, a manufacturing method thereof, a silicon plate, a substrate of a solar cell and a target base material for sputtering.

SOLUTION: The method of manufacturing a unidirectional solidified silicon ingot C has a process for dipping a polycrystalline silicon seed crystal S into a silicon molten liquid L stored in a crucible 1 and pulling up the silicon ingot with the seed crystal, wherein the seed crystal is planar.
