  • Publication number: 20220296001
    Abstract: This invention includes a method to produce a customizable and user-configurable mattress foam core which comprises a plurality of transversely extended foam rods that were cut during the mattress production process. These transversely extended foam rods typically have a cross section of a convex shape, including triangles, squares, rectangles, circles, ovals and hexagons. These transversely extended foam rods can be replaced with foam rods of different firmness, creating more than 10 zones with varying firmness in each zone thus tailoring to the sleeper's needs, adjusting for their differences in height, weight, sleeping position, and comfort preference. Also, these zones together allow the user to configure the mattress for spinal alignment. The transversely extended replacement foam rods typically have cross sections that are substantially the same shape as the pre-cut foam rods, but may also be of different shape.

  • Patent number: 11136665
    Abstract: Embodiments of the invention contemplate a shadow ring that provides increased or decreased and more uniform deposition on the edge of a wafer. By removing material from the top and/or bottom surfaces of the shadow ring, increased edge deposition and bevel coverage can be realized. In one embodiment, the material on the bottom surface is reduced by providing a recessed slot on the bottom surface. By increasing the amount of material of the shadow ring, the edge deposition and bevel coverage is reduced. Another approach to adjusting the deposition at the edge of the wafer includes increasing or decreasing the inner diameter of the shadow ring. The material forming the shadow ring may also be varied to change the amount of deposition at the edge of the wafer.

  • Publication number: 20130284090
    Abstract: Methods and apparatus for depositing uniform boron-containing films are disclosed. A first precursor is delivered to a chamber through a first pathway having a first flow controller and a composition sensor. A second precursor is delivered by a second pathway, including a second flow controller, to a mixing point fluidly coupling the first and second pathways. A controller is coupled to the vibration sensor and the first and second flow controllers. The first precursor may be a mixture of diborane and a diluent gas, and the second precursor is typically a diluent gas. The flow rate of the first precursor may be set by determining a concentration of diborane in the first precursor from the composition sensor reading, and setting the flow rate to maintain a desired flow rate of diborane. The flow rate of the second precursor may be set to maintain a desired flow to the chamber.

  • Patent number: 8513129
    Abstract: Methods for manufacturing a semiconductor device are provided. In one embodiment, a method includes providing a base material having a first film stack deposited thereon, wherein the base material is formed over the substrate and has a first set of interconnect features. The first film stack comprises a first amorphous carbon layer deposited on a surface of the base material, a first anti-reflective coating layer deposited on the first amorphous carbon layer, and a first photoresist layer deposited on the first anti-reflective coating layer. The first photoresist layer is patterned by shifting laterally a projection of a mask on the first photoresist layer relative to the substrate a desired distance, thereby introducing into the first photoresist layer a first feature pattern to be transferred to the underlying base material, wherein the first feature pattern is not aligned with the first set of interconnect features.

    Abstract: Embodiments described herein relate to a substrate processing system that integrates substrate edge processing capabilities. Illustrated examples of the processing system include, without limitations, a factory interface, a loadlock chamber, a transfer chamber, and one or more twin process chambers having two or more processing regions that are isolatable from each other and share a common gas supply and a common exhaust pump. The processing regions in each twin process chamber include separate gas distribution assemblies and RF power sources to provide plasma at selective regions on a substrate surface in each processing region. Each twin process chamber is thereby configured to allow multiple, isolated processes to be performed concurrently on at least two substrates in the processing regions.

  • Publication number: 20120208373
    Abstract: A method for depositing an amorphous carbon layer on a substrate includes the steps of positioning a substrate in a chamber, introducing a hydrocarbon source into the processing chamber, introducing a heavy noble gas into the processing chamber, and generating a plasma in the processing chamber. The heavy noble gas is selected from the group consisting of argon, krypton, xenon, and combinations thereof and the molar flow rate of the noble gas is greater than the molar flow rate of the hydrocarbon source. A post-deposition termination step may be included, wherein the flow of the hydrocarbon source and the noble gas is stopped and a plasma is maintained in the chamber for a period of time to remove particles therefrom.
