APPARATUS FOR FLOAT GROWN CRYSTALLINE SHEETS

摘要

An apparatus for forming a crystalline sheet from a melt may include a crucible to contain the melt. The apparatus may also include a cold block configured to deliver a cold region proximate a surface of the melt, the cold region operative to generate a crystalline front of the crystalline sheet and a crystal puller configured to draw the crystalline sheet in a pull direction along the surface of the melt, wherein a perpendicular to the pull direction forms an angle with respect to the crystalline front of less than ninety degrees and greater than zero degrees.
