  • Patent number: 10468417
    Abstract: A fabricating method of a stop layer includes providing a substrate. The substrate is divided into a memory region and a peripheral circuit region. Two conductive lines are disposed within the peripheral circuit region. Then, an atomic layer deposition is performed to form a silicon nitride layer to cover the conductive lines. Later, after forming the silicon nitride layer, a silicon carbon nitride layer is formed to cover the silicon nitride layer. The silicon carbon nitride layer serves as a stop layer.

  • Publication number: 20190329029
    Abstract: A flexible thin film metal oxide electrode fabrication methods and devices are provided and illustrated with thin film polyimide electrode formation and IrOx chemical bath deposition. Growth factors of the deposited film such as film thickness, deposition rate and quality of crystallites can be controlled by varying the solution pH, temperature and component concentrations of the bath. The methods allow for selective deposition of IrOx on a flexible substrate (e.g. polyimide electrode) where the IrOx will only coat onto an exposed metal area but not the entire device surface. This feature enables the bath process to coat the IrOx onto every individual electrode in one batch, and to ensure electrical isolation between channels. The ability to perform selective deposition, pads for external connections will not have IrOx coverage that would otherwise interfere with a soldering/bumping process.

  • Patent number: 10320644
    Abstract: A traffic analyzer of a provider network identifies endpoint categories into which traffic directed to or from a first isolated virtual network of the provider network is to be classified. A first endpoint category includes an endpoint configured in a second isolated virtual network. Using packet-level metrics collected at virtualization management components of virtualization hosts, the traffic analyzer determines the amount of data transmitted between the first isolated virtual network and the various endpoint categories during selected time intervals. The traffic analyzer provides the categorized traffic amounts as input to a predictive model, and stores expected future traffic trends generated by the model.

  • Publication number: 20190173774
    Abstract: A system includes a provider network and a client network connected via a dedicated physical connection. The client network and the provider network exchange routing information using routing protocol messages, such as border gateway protocol (BGP) update messages exchanged during a BGP session. A provider network includes tag field values in outgoing routing protocol messages that indicate a portion of the provider network wherein resources of the provider network associated with a corresponding route are located. The client network may use the tag field value to determine whether to add the route to a routing table of the client network. A client network may also include tag field values in outgoing routing protocol messages to a provider network. The tag field values may indicate what portions of the provider network are to receive the routes from the client network. For example a tag field value may indicate that a route is to be propagated within a limited portion of the provider network.

  • Patent number: 10282669
    Abstract: Techniques are disclosed for determining a possible cause of a problem in a computer system. A trouble-shooting component of the computer system may perform forward chaining on the available data to determine one or more hypotheses of the cause of the problem. The component may then perform backward chaining on the hypotheses to determine missing information that, if known, would increase or decrease the likelihood of the hypotheses being true. Then, the component may perform Bayesian probability analysis on the known and missing information to determine a probability that each hypothesis is correct.

  • Patent number: 9935816
    Abstract: A technology is described for updating an Autonomous System Number (ASN) in a Border Gateway Protocol (BGP) routing configuration. An example method may include receiving a request to update a BGP routing configuration on a gateway with an ASN associated with a customer. In response to the request, the BGP routing configuration on the gateway may be updated to replace a default ASN associated with a computing service provider with the ASN associated with the customer. The BGP routing configuration on the gateway may also be updated to allow the ASN associated with the customer to appear in an Autonomous System (AS) path at least twice, thereby allowing for BGP routes to be exchanged between gateways.
