Abstract
An integrated die and crucible system used an integrated die and crucible assembly that allows for improved sapphire sheet growing as result of targeted heat features and controls of the integrated die and crucible system and corresponding systems used to form the integrated die and crucible assembly, which include in part heat plugs, as well specific wall thicknesses about the die and crucibles.
Claims14
A thermal venting system for use with a single-crystal sapphire sheet producing system comprising:
- a base insulating module having a plurality of venting apertures disposed along a length of the base insulating module, wherein the upper portion of the base insulating module is configured to support a die for the single-crystal sapphire sheet producing system to be disposed thereon and partially insulate the die and wherein the base insulating module further includes a base section having a perimeter portion that is wider than a central portion of the base module;
- and
- a plurality of heat plugs each configured to be removably insertable into the plurality of venting apertures, wherein each heat plug is configured to thermally vent or insulate a section of the die disposed on the base insulation module based upon the distance each heat plug is inserted in each of the plurality of apertures.
A method for controlling the heat profile along the length of a die for use with a single-crystal sapphire sheet-producing system comprising the steps of:
- positioning the die on a thermal control system configured to provide insulation and thermal ventilation to the die, wherein the thermal control system is comprised of:
- a base insulating module having a plurality of apertures disposed along the length of the base module, and
- a plurality of heat plugs configured to be removably insertable into each of the plurality of apertures at varying depths;
- adjusting the depth of each heat plug within each of the plurality of apertures to create a first thermal profile;
- and
- adjusting the depth of each heat plug within each of the plurality of apertures to create a second thermal profile.
