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.

摘要： In one embodiment, a sheet production apparatus comprises a vessel configured to hold a melt of a material. A cooling plate is disposed proximate the melt and is configured to form a sheet of the material on the melt. A first gas jet is configured to direct a gas toward an edge of the vessel. A sheet of a material is translated horizontally on a surface of the melt and the sheet is removed from the melt. The first gas jet may be directed at the meniscus and may stabilize this meniscus or increase local pressure within the meniscus.

摘要： A method of horizontal ribbon growth from a melt includes forming a leading edge of the ribbon using radiative cooling on a surface of the melt, drawing the ribbon in a first direction along the surface of the melt, and removing heat radiated from the melt in a region adjacent the leading edge of the ribbon at a heat removal rate that is greater than a heat flow through the melt into the ribbon.

摘要： An apparatus for growing a crystalline sheet from a melt includes a cold block assembly. The cold block assembly may include a cold block and a shield surrounding the cold block and being at an elevated temperature with respect to that of the cold block, the shield defining an opening disposed along a surface of the cold block proximate a melt surface that defines a cold area comprising a width along a first direction of the cold block, the cold area operable to provide localized cooling of a region of the melt surface proximate the cold block. The apparatus may further include a crystal puller arranged to draw a crystalline seed in a direction perpendicular to the first direction when the cold block assembly is disposed proximate the melt surface.

摘要： A method and apparatus for forming a sheet are disclosed. A melt is cooled and a sheet is formed on the melt. This sheet has a first thickness. The sheet is then thinned from the first thickness to a second thickness using, for example, a heater or the melt. The cooling may be configured to allow solutes to be trapped in a region of the sheet and this particular sheet may be thinned and the solutes removed. The melt may be, for example, silicon, silicon and germanium, gallium, or gallium nitride.
