Latest Patents

Joseph S. Ciofalo holds a patent for an "Epitaxial heater apparatus and process." This invention features a quartz envelope that supports a resistance heater. The design includes a boron nitride pill box configured core that supports resistance heater windings. The core has a base with a cylindrical upper portion that defines a hollow chamber and an upper annular ring. A circular top consists of an upper circular portion and a lower circular portion that mates with the base. The annular ring surface is in thermal contact with the upper circular portion to effectively transfer heat from the annular ring to the circular top. A zirconia insulator cups the core, providing heat insulation, along with a heat shield coating in the quartz envelope's interior. Arrays of quartz envelope heaters facilitate the mass production of semiconductors. The horizontal configuration includes a laminar flow head that is disposed at an angle to the horizontal. In operation, a current applied to the windings generates high temperatures for chemical vapor deposition, allowing for the growth of semiconductors on substrates positioned above the envelope with minimal energy utilization. When heated, the heat is transmitted significantly upward along the annular surface of the core, then to the top of the core above the hollow chamber. This design achieves a generally flat temperature across the surface of the core's top, maintaining that uniform temperature when the heat is transmitted to a substrate. Joseph S. Ciofalo has 1 patent to his name.
