Patents by Inventor Joshua J. Podesta

Joshua J. Podesta has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20110121503
    Abstract: Embodiments of the present invention generally relate to methods and apparatus for chemical vapor deposition (CVD) on a substrate, and, in particular, to a process chamber and components for use in metal organic chemical vapor deposition. The apparatus comprises a chamber body defining a process volume. A showerhead in a first plane defines a top portion of the process volume. A carrier plate extends across the process volume in a second plane forming an upper process volume between the showerhead and the susceptor plate. A transparent material in a third plane defines a bottom portion of the process volume forming a lower process volume between the carrier plate and the transparent material. A plurality of lamps forms one or more zones located below the transparent material. The apparatus provides uniform precursor flow and mixing while maintaining a uniform temperature over larger substrates thus yielding a corresponding increase in throughput.

  • Publication number: 20090194026
    Abstract: One embodiment of a processing system for fabricating compound nitride semiconductor devices comprises one or more processing chamber operable with form a compound nitride semiconductor layer on a substrate, a transfer chamber coupled with the processing chamber, a loadlock chamber coupled with the transfer chamber, and a load station coupled with the loadlock chamber, wherein the load station comprises a conveyor tray movable to convey a carrier plate loaded with one or more substrates into the loadlock chamber. Compared to a single chamber reactor, the multi-chamber processing system expands the potential complexity and variety of compound structures. Additionally, the system can achieve higher quality and yield by specialization of individual chambers for specific epitaxial growth processes. Throughput is increased by simultaneous processing in multiple chambers.
