摘要:
An improved chemical mechanical polishing retaining ring. A representative embodiment comprises a base portion made from a wear-resistant plastic material, and an upper portion, or backbone portion, made from a stiffer and more wear resistant material. One of the base or backbone portion is preferably overmolded onto the other. The base portion can be generally defined by a flat pad-contacting surface, an outer surface, and an inner surface. The base portion can additionally include channels extending from the outer surface to the inner surface to facilitate transfer of slurry to and from the substrate to be polished during the process. One or both of the base portion or backbone portion further includes a plurality of circular ribs that serve to create additional bonding surface with the overmolded material. The retaining ring may additionally includes a plurality of bosses with threaded insert holes by which the retaining ring is attached to a chemical mechanical polishing system.
摘要:
A substrate kinematic coupling or guide plate for a substrate carrier having textured or patterned surfaces at the points of contact to reduce frictional forces generated between automated processing equipment and the kinematic coupling. The textured surface reduces the contact area between the processing equipment and the contact portion of the kinematic coupling, thereby reducing the resultant frictional force. By reducing the frictional force, the substrate carrier more readily settles on the mounting pins of the processing equipment, thus avoiding intolerable height and angular deviations during automated access to the substrates. Textures include, but are not limited to, a knurl pattern, ridges running laterally along the contact portions, and ridges running longitudinally along the contact portions. The textures may be formed by a blow molding, injection molding or in an overmolding process, or by a machining or imprinting process.

A first appliance for ensuring data integrity in network memory is disclosed. The first appliance includes a processor and a communications interface that communicates over a communication network with a second appliance of the network memory. The processor determines whether reconciliation between a first peer state information in the first appliance and a second peer state information in the second appliance is needed. The first peer state information and the second peer state information track the status of data in the network memory. The processor determines an action to reconcile the first peer state information with the second peer state information based on a positive determination that the reconciliation is needed. The processor then performs the action to reconcile the first peer state information with the second peer state information.

A semiconductor wafer, substrate, or reticle storage or shipping device that includes a photochromic indicator of exposure to undesired electromagnetic radiation. The present invention includes the incorporation of a photochromic material into the plastic used to fabricate at least a portion of a semiconductor wafer, disk, or reticle shipping or storage containers. The container may include photochromic material in the form of a transparent window or a larger portion of the container. the photochromic material may change color or darkness in response to exposure to a selected range of wavelengths of light.

The Namespace Management System comprises a run-time configurable state information management system that evaluates a request within a semantic domain defined by the state information at a given moment in time. The Namespace Management System comprises a Namespace Management application, executing on a computer system that is connected to the Internet or other Autonomous System. The Namespace Management System is programmatically and dynamically configurable to take part in and administer a multiplicity of namespaces, each of which contains listings, data, and services or other state information required to satisfy a request and/or interact with callable services. A multiplicity of Namespace Management Systems can register services, provide services, discover services, communicate with services, and participate in one or more dynamic network namespaces, with each Namespace Management System having at least one associated dynamic network namespace listing. At run-time, a Namespace Management System can register a subscriber's present point of presence to associate with its dynamic network namespace listing. The Namespace Management System provides dynamic point of presence registration for namespace listings and through a scheme handler service to resolve a namespace listing reference, which is given as a Uniform Resource Identifier, to the present point of presence for the namespace listing. This process enables the Namespace Management System to provide web services independent of the physical location of the subscriber.
摘要:
The present teachings are generally directed to methods for normalizing at least one species of small nucleic acid that is present in a population of small nucleic acid species, wherein the relative concentration of at least one small nucleic acid species is substantially greater than the relative concentration of at least one other small nucleic acid species in the population. At least one small nucleic acid species is normalized using a multiplicity of primers comprising degenerate sequences. In some embodiments, a small nucleic acid species is identified by inserting at least part of an extension product from a normalized population into a vector and subsequently sequencing the insert. In some embodiments, a small nucleic acid species is identified by determining the sequence of at least part of an extension product.

A personal communications device is integrated with a hat. The hat provides support for the communications device and may also protect a user against the elements (e.g., rain, sun, snow). The hat may be made of any of a variety of lightweight, “breathable” materials, such as cloth, straw, or nylon mesh, for example. The hat may also be of any style (men's or women's), including, but not limited to; billed caps, such as baseball caps; brimmed caps, such as a fedora; and brimless hats, such as stocking or watch caps. The communications device may take the form of a two-way radio or a cellular telephone, for example.
