  • Publication number: 20190341227
    Abstract: One or more embodiments described herein generally relate to selective deposition of substrates in semiconductor processes. In these embodiments, a precursor is delivered to a process region of a process chamber. A plasma is generated by delivering RF power to an electrode within a substrate support surface of a substrate support disposed in the process region of the process chamber. In embodiments described herein, delivering the RF power at a high power range, such as greater than 4.5 kW, advantageously leads to greater plasma coupling to the electrode, resulting in selective deposition to the substrate, eliminating deposition on other process chamber areas such as the process chamber side walls. As such, less process chamber cleans are necessary, leading to less time between depositions, increasing throughput and making the process more cost-effective.

  • Publication number: 20190338071
    Abstract: The present invention relates to a process for the production of a thermoplastic polyester using a reaction mixture comprising a dicarboxylic acid having a melting temperature of ?200° C. wherein the dicarboxylic acid is introduced to the process in the form of particles having an average particle diameter of ?100 ?m. Such process results in a reduction of the polymerisation time. Furthermore, it allows for the production of thermoplastic polyesters having a desired balance of intrinsic viscosity and carboxylic end group content at a reduced polymerisation time.

  • Patent number: 10432522
    Abstract: An intermediate node obtains a lead packet of a plurality of packets in a session having a unique session identifier, modifies the lead packet to identify at least the intermediate node and also to identify source and destination port numbers assigned by the intermediate node for a possible forward association, and then forwards the lead packet toward the destination node though an intermediate node electronic output interface to the IP network. The intermediate node also may receive, through an intermediate node electronic input interface in communication with the IP network, a backward message from a next node having a next node identifier. Both the intermediate node and the next node form an association between the intermediate node identifier, the next node identifier, and the source and destination port numbers assigned by the intermediate node. This association is part of a forward association for the intermediate node and is part of a return associate for the next node.

  • Publication number: 20190252158
    Abstract: The present disclosure generally relates to processing chamber seasoning layers having a graded composition. In one example, the seasoning layer is a boron-carbon-nitride (BCN) film. The BCN film may have a greater composition of boron at the base of the film. As the BCN film is deposited, the boron concentration may approach zero, while the relative carbon and nitrogen concentration increases. The BCN film may be deposited by initially co-flowing a boron precursor, a carbon precursor, and a nitrogen precursor. After a first period of time, the flow rate of the boron precursor may be reduced. As the flow rate of boron precursor is reduced, RF power may be applied to generate a plasma during deposition of the seasoning layer.

  • Patent number: 10380721
    Abstract: This disclosure covers systems and methods that sharpen the appearance of a digital illustration while moving the digital illustration. In certain embodiments, upon receiving a command to move a digital illustration, the disclosed systems and methods move the digital illustration (and its constituent line segments) to positions that both sharpen the appearance of the digital illustration and respond to the command. To facilitate sharpening the appearance of a digital illustration as part of a seemingly continuous movement, in some embodiments, the disclosed systems and methods move a blurry digital illustration to a position that sharpens the appearance of blurry axial-line segments by translating the digital illustration according to a translation vector and a command to move the digital illustration.

  • Publication number: 20190215270
    Abstract: A packet routing method for directing packets of a session in an IP network causes an intermediate node to obtain a lead packet of a plurality of packets in a given session. The intermediate node has an electronic interface in communication with the IP network and obtains the lead packet through that same interface. The method maintains, in a routing database, state information relating to a plurality of sessions in the IP network. Each session includes a single stateful session path formed by an ordered plurality of nodes in the IP network, and the state information includes information about the ordered plurality of nodes in the sessions. The method further accesses the routing database to determine the state of a plurality of sessions, and forms a stateful given path for packets of the given session across the IP network as a function of the state information in the routing database.

  • Patent number: 10348812
    Abstract: Techniques for managing session data in a computer system having a plurality of servers establishing sessions with clients. Communications from any particular client are forwarded to the server assigned to handle that client. A load balancer may determine that any particular session for any particular client should be moved between servers, based on load balancing criteria. In this case, the load balancer causes session data for the server assigned to the client to be transferred to a different server. Acknowledgment signals are sent between the servers and load balancer to indicate completion status. Load balancer maintains backup data at secondary servers which can be brought online when a primary server becomes unresponsive. A method, system, and computer-readable medium are provided.
