  • Patent number: 11970566
    Abstract: Disclosed is a method of manufacturing a polyurethane filter foam having excellent air permeability, elasticity, and restoring force. In the method of manufacturing the polyurethane filter foam, the cell size of the filter foam is made regular by controlling the pressure by adjusting the diameter of the foaming head of a foaming machine, rather than adding a cell opener, cell irregularity caused by poor dispersion of the cell opener is alleviated, and air permeability, porosity, and compression set are excellent.

  • Patent number: 10847376
    Abstract: A first material layer, a second material layer, and a photoresist layer may be formed over a substrate. The second material layer may be patterned by transfer of a lithographic pattern therethrough. A conformal spacer layer may be formed over the patterned second material layer in a chamber enclosure of an in-situ deposition-etch apparatus. Spacer films may be formed by anisotropically etching the conformal spacer layer in the chamber enclosure of the in-situ deposition-etch apparatus. The first material layer may be anisotropically etched using a combination of the patterned second material layer and the spacer films as an etch mask in the in-situ deposition-etch apparatus. A high fidelity pattern may be transferred into the first material layer with reduced line edge roughness, reduced line width roughness, and without enlargement of lateral dimensions of openings in the first material layer.

  • Patent number: 10269620
    Abstract: Contacts to peripheral devices extending through multiple tier structures of a three-dimensional memory device can be formed with minimal additional processing steps. First peripheral via cavities through a first tier structure can be formed concurrently with formation of first memory openings. Sacrificial via fill structures can be formed in the first peripheral via cavities concurrently with formation of sacrificial memory opening fill structures that are formed in the first memory openings. Second peripheral via cavities through a second tier structure can be formed concurrently with formation of word line contact via cavities that extend to top surfaces of electrically conductive layers in the first and second tier structures. After removal of the sacrificial via fill structures, the first and second peripheral via cavities can be filled with a conductive material to form peripheral contact via structures concurrently with formation of word line contact via structures.
