  • Patent number: 9704720
    Abstract: An integrated circuit may be formed by forming a sacrificial silicon nitride feature. At least a portion of the sacrificial silicon nitride feature may be removed by placing the integrated circuit in a two-step oxidized layer etch tool and removing a surface layer of oxidized silicon from the sacrificial silicon nitride feature using a two-step etch process. The two-step etch process exposes the integrated circuits to reactants from a plasma source at a temperature less than 40° C. and subsequently heating the integrated circuit to 80° C. to 120° C. while in the two-step oxidized layer etch tool. While the integrated circuit is in the two-step oxidized layer etch tool, without exposing the integrated circuit to an ambient containing more than 1 torr of oxygen, at least a portion of the sacrificial silicon nitride feature is removed using fluorine-containing etch reagents, substantially free of ammonia.

  • Patent number: 8572208
    Abstract: A method of processing requests for resources in a system in which a plurality of content providers provide multiple resources. Content providers offload the serving of some of their resources to a shared content delivery network (CDN) formed by a plurality of servers. The CDN is shared among the content providers. Some of a content provider's content may be served from an origin server associated with that content provider, while requests for other content from that content provider are served from the shared CDN.

  • Patent number: 8478903
    Abstract: A system in which a plurality of content providers provide multiple resources to multiple clients, wherein each content provider provides at least some resources via one or more content sources associated with that content provider. A client requests a resource from a content provider, where the resources includes references to other resources of the content provider. Referenced resources are served to requesting clients from a shared content delivery network (CDN) formed from a plurality of servers distinct from content sources associated with said content providers. The content sources may be origin servers associated with the respective content providers. The referenced resources may be video content, audio content, text, image content, web pages, HTML files, XML files, files in a markup language, documents, hypertext documents, data files, and embedded resources.

  • Patent number: 8473613
    Abstract: A plurality of repeater servers form a shared content delivery network (CDN) to serve resources to clients on behalf of a plurality of content providers. First and second resources are associated with a first content provider, the first resource referencing the second resource. The second resource is associated with a domain of the shared CDN. Responsive to a request that causes the first resource to be served to a client from a server in a domain associated with the first content provider, a CDN server is identified in the domain associated with the shared CDN to serve the second resource to the client. The CDN server is selected based, at least in part, on load conditions on at least some of the CDN servers, and on the client's location.

  • Patent number: 8468245
    Abstract: A method for delivering resources to clients in a distributed computing environment. At least a first resource associated with a first content provider and maintained on an origin server references a second resource. The second resource is associated with a network formed by a plurality of repeater servers operable to serve the second resource to clients on behalf of the first content provider, the origin server being distinct from the plurality of repeater servers. Responsive to a request that causes the first resource to be served to a client from the origin server, at least one of the plurality of repeater servers is selected to serve the second resource to the client. If a copy of the second resource is available on the selected repeater server, the copy of the second resource is served to the client from the selected repeater server; otherwise, if a copy of the second resource is not available on the selected repeater server, the second resource is replicated on the selected repeater server.

  • Patent number: 8281035
    Abstract: A method for delivering resources in a distributed computing environment, wherein at least a first resource and a second resource are associated with a content provider, and wherein the first resource references the second resource via a first uniform resource locator (URL), the first URL having a first domain name that resolves to a server associated with a domain of the content provider. The second resource is associated with a domain name that resolves to a content delivery network (CDN) formed by a plurality of repeater servers. The domain of the CDN may be distinct from the domain of the content provider. Responsive to a request that causes the first resource to be served to a client from an origin server associated with the content provider's domain, the second domain name in the second URL is resolved to identify a repeater server in the CDN's domain from which to serve the second resource to the client.

  • Publication number: 20120131058
    Abstract: A device maintains multiple signatures, including at least one signature for each of a plurality of data items. At least corresponding signature for a data item is based at least in part on a given function of at least some of the contents of that data item. The device receives a particular sequence of bits and determines at least one signature for that particular sequence of bits, based at least in part on the given function of at least some of the particular sequence of bits. The device determines, based at least in part on the signature for the particular sequence of bits, and using the multiple signatures, whether the device may access the particular sequence of bits.
