  • Patent number: 11417553
    Abstract: A method and apparatus for detecting and correcting incoming substrate deformation is disclosed. Substrates are positioned in a first process chamber, where the presence and type of substrate bow is detected. Based upon the detection of substrate bow, and a determination of whether the substrate has a compressive bow or a tensile bow, a substrate processing program is selected for execution. The substrate processing program can be executed in the first process chamber or in a second process chamber to correct or alleviate the bow prior to or during further processing of the substrate.

  • Patent number: 11011371
    Abstract: Embodiments disclosed herein relate to methods for forming memory devices, and more specifically to improved methods for forming a dielectric encapsulation layer over a memory material in a memory device. In one embodiment, the method includes thermally depositing a first material over a memory material at a temperature less than the temperature of the thermal budget of the memory material, exposing the first material to nitrogen plasma to incorporate nitrogen in the first material, and repeating the thermal deposition and nitrogen plasma operations to form a hermetic, conformal dielectric encapsulation layer over the memory material. Thus, a memory device having a hermetic, conformal dielectric encapsulation layer over the memory material is formed.

  • Publication number: 20080133423
    Abstract: The invention provides a technique for computerized multi-variable negotiation in networking environment. A user initiates a transaction by identifying a variety of parameters, specifying which parameters may be modified, and indicating limits of acceptable modification. This latter feature is particularly important with respect to entertaining counteroffers. The initiator of a negotiation selects the parties with whom they wish to negotiate. The parameters describing a transaction are sent to negotiating parties who may submit bids. The bids may contain new terms created by altering one or more of the parameters. These bids are summarized and presented to the initiator. The initiator of the negotiation reviews the bids and (1) eliminates bids from consideration, 2) accepts a bid, or (3) selects bids for advanced negotiations. This process continues until the parties decide to close the deal. A history of each involved in a negotiation is maintained in a database.
