Removing a sheet from the surface of a melt using elasticity and buoyancy

摘要

Embodiments related to sheet production are disclosed. A melt of a material is cooled to form a sheet of the material on the melt. The sheet is formed in a first region at a first sheet height. The sheet is translated to a second region such that it has a second sheet height higher than the first sheet height. The sheet is then separated from the melt. A seed wafer may be used to form the sheet.

1. A method of sheet production comprising:
cooling a melt of a material to form a sheet of said material on a surface of said melt in a first region at a first sheet height; translating said sheet horizontal to said surface of said melt and raising a first portion of said sheet vertically from said surface of said melt such that said first portion of said sheet is disposed in a second region and a second portion of said sheet is disposed in said first region, wherein said first portion of said sheet has a second sheet height, said second portion of said sheet has a first sheet height, said first sheet height being lower than said second sheet height, and said first portion of said sheet being parallel to said second portion of said sheet; and separating said sheet from said melt in said second region at said second sheet height.
