  • Publication number: 20180066354
    Abstract: Wafer boats for the plasma treatment of disc-shaped wafers, in particular semiconductor wafers for semiconductor or photovoltaic applications, and a plasma treatment apparatus for wafers are described. A wafer boat comprises a plurality of first carrier elements which are positioned parallel to one another, wherein each first carrier element has a plurality of carrier slits for receiving the edge of a wafer or wafer pair, and a plurality of second carrier elements which are positioned parallel to one another, which are each electrically conductive and have at least one recess for holding the edge region of at least one wafer or one wafer pair. An alternative wafer boat comprises a plurality of electrically conductive plate shaped carrier elements, which are positioned parallel to one another and which are less than half as high as the wafers to be received, wherein the carrier elements each have on their opposing sides at least three carrier elements for receiving wafers.

  • Publication number: 20140289094
    Abstract: An in-line hardware message filter device inspects incoming securities transactions. The invention is implemented as an integrated circuit (IC) device which contains computer code in the form of on-chip hardware instructions. Data messages comprising orders enter the device in exchange-specific formats. Messages that satisfy pre-determined risk assessment filters are allowed to pass through the device to the appropriate securities exchange for execution. The system functions as a passive device for all legitimate network traffic passing directly or indirectly between a customer's computer and a securities exchange's order-acceptance computer. Advantageously, the invention allows the broker-dealer to check and pass messages or orders as they come through the system without having to store the full message before making a risk assessment decision. The hardware-only nature of the invention serves to maximize the speed of order validation and to perform pre-trade checks in a cut-through or store-and-forward mode.
