  • Patent number: 10566441
    Abstract: Methods of forming integrated circuits are provided herein. In an embodiment, a method of forming an integrated circuit includes providing a semiconductor substrate. The semiconductor substrate includes a plurality of gate structures that have sidewalls spacers disposed adjacent to the gate structures. A gap is defined between sidewall spacers of adjacent gate structures. The method proceeds with decreasing an aspect ratio between a width of the gap at an opening thereto and a depth of the gap, wherein an aspect ratio between a width of the gap at a base of the sidewall spacers and the depth of the gap remains substantially unchanged after decreasing the aspect ratio between the width of the gap at the opening thereto.

The coils may be coupled is series and or parallel configurations. The primary stationary receive coil may be integrated within or appended to a housing. The secondary rotatable receive coil may be integrated within or coupled to a rotatable clip coupled to the housing. Rotation of the clip extends a charging configuration with which to charge the primary stationary receive coil and the secondary rotatable receive coil.

  • Patent number: 10410854
    Abstract: The present disclosure generally relates to methods for cleaning the backside of a wafer. A wet cleaning method may be used by stripping off the uppermost spacer layers on the backside of the wafer using a cleaning solution. In one embodiment, hydrogen fluoride (HF) solution may be employed to remove the nitride/oxide spacer layer. In another embodiment, a dry cleaning method may be employed to etch the wafer at the bevel region. Residues are completely removed from the wafer backside. This method improves the yield and storage life of the semiconductor wafers.

  • Patent number: 10191705
    Abstract: During processing of job documents in a document processing workflow, execution of the workflow is stopped at a previously defined first sequentially processed node until no more of the job documents can be directed to the first sequentially processed node by the workflow. Then, the job documents that have been stopped at the first sequentially processed node are arranged in a document order, and the sequentially processed nodes are executed for each of the multiple job documents that have been stopped (and such job documents are processed one at a time through the sequentially processed nodes). Thus, execution waits until an immediately previous one of the job documents (in the document order) has finished processing at a previously defined last sequentially processed node before starting processing an immediately subsequent one of the job documents (in the document order) at the first sequentially processed node.

  • Patent number: 9431364
    Abstract: A multi-chip package is disclosed that has a construction capable of preventing and/or reducing electrical shorts caused by shifts in bond wires. The multi-chip package includes a die attach formed between connection points of a bond wire. The die attach is made of a non-conductive material and can be constructed so as to support or encompass a portion of the bond wire. By contacting the bond wire, the die attach restricts the motion of the bond wire by acting as a physical barrier to the bond wire's movement and/or as a source of friction. In this manner, undesired position shifts of the bond wires can be prevented, reducing device failures and allowing for improved manufacturing allowances.

  • Patent number: 9139924
    Abstract: For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.

  • Patent number: 9077645
    Abstract: A Multiple Registration Protocol (MRP) advertisement control capability is provided. A method includes receiving an MRP advertisement at a device configured as an interface between a core domain and a local domain and determining handling of the MRP advertisement at the device using at least one MRP policy stored on the device. The core domain may be a Provider Backbone Bridging (PBB) network or other suitable core network. The local domain may be one of a PBB network, a Provider Bridging Network (PBN), a Metropolitan Area Network (MAN), and the like. In one case, when the MRP advertisement is associated with a local service of the local domain, the MRP policy indicates that the MRP advertisement is not to be forwarded via the core domain.
