George R. Seaton 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).

  • Mesa-type high voltage switching integrated circuit
    Patent number: 4068255
    Abstract: The voltage characteristics of switching integrated circuits of the type disclosed in U.S. Patent No. 3,918,083 are improved by employing a mesa-type etch to physically separate the four vertical transistors. Interconnection may be carried out by wire bonding respective collector and emitter areas or, preferably, passivating materials are used to fill the etched grooves and interconnection is carried out by vapor deposition (e.g. planar) techniques.
    Type: Grant
    Filed: December 23, 1976
    Date of Patent: January 10, 1978
    Assignee: Dionics, Inc.
    Inventors: Bernard L. Kravitz, George R. Seaton
  • Monolithic, junction isolated photrac
    Patent number: 4001866
    Abstract: A photosensitive integrated circuit switch that operates in the same manner as back-to-back photosensitive SCR's. The invention combines the monolithic, junction-isolated construction of the basic photrac, described in U.S. Pat. No. 3,918,083, and the operational characteristics of a dielectrically isolated photrac, described in co-pending application Ser. No. 616,040, but incorporates the single-quadrant gate-triggering feature of the latter. Its simplified construction makes it advantageous in many applications.

  • Semiconductive devices with integrated circuit switches
    Patent number: 4001867
    Abstract: A bilateral, switching integrated circuit is described in U.S. Pat. No. 3,918,083. The present application discloses variations of the basic structure and devices incorporating both the basic structure and the variants. Included are a photosensitive, zero-crossing optoisolator, relay structures, a switch of greatly increased light sensitivity employing photodarlingtons, and a dielectrically isolated switch that can be triggered by light or gated injection currents.
