Patent number: 8430992Abstract: Protective self aligned buffer (PSAB) layers are layers of material that are selectively formed at the surface of metal layers in a partially fabricated semiconductor device. In a Damascene interconnect, PSAB layer typically resides at an interface between the metal layer and a dielectric diffusion barrier layer. PSAB layers promote improved adhesion between a metal layer and an adjacent dielectric diffusion barrier layer. Further, PSAB layers can protect metal surfaces from inadvertent oxidation during fabrication process. A PSAB layer may be formed entirely within the top portion of a metal layer, by, for example, chemically converting metal surface to a thin layer of metal silicide. Thickness of PSAB layers, and, consequently resistance of interconnects can be controlled by partially passivating metal surface prior to formation of PSAB layer. Such passivation can be accomplished by controllably treating metal surface with a nitrogen-containing compound to convert metal to metal nitride.Type: GrantFiled: April 20, 2010Date of Patent: April 30, 2013Assignee: Novellus Systems, Inc.Inventors: Kaushik Chattopadhyay, Bart van Schravendijk

Patent number: 8409353Abstract: A method and apparatus for oxidizing materials used in semiconductor integrated circuits, for example, for oxidizing silicon to form a dielectric gate. An ozonator is capable of producing a stream of least 70% ozone. The ozone passes into an RTP chamber through a water-cooled injector projecting into the chamber. Other gases such as hydrogen to increase oxidation rate, diluent gas such as nitrogen or O2, enter the chamber through another inlet. The chamber is maintained at a low pressure below 20 Torr and the substrate is advantageously maintained at a temperature less than 800° C. Alternatively, the oxidation may be performed in an LPCVD chamber including a pedestal heater and a showerhead gas injector in opposition to the pedestal.Type: GrantFiled: October 20, 2011Date of Patent: April 2, 2013Assignee: Applied Materials, Inc.Inventors: Yoshitaka Yokota, Sundar Ramamurthy, Vedapuram Achutharaman, Cory Czarnik, Mehran Behdjat, Christopher Olsen

Patent number: 8398813Abstract: The present invention provides a processing apparatus and a processing method, both of which can carry out a low-temperature process to allow active gas species to react with an oxide film on an object to be processed to form a product film and a heating process to heat the object to a predetermined temperature to evaporate the product film, in succession. This processing apparatus 12 is provided with a shielding plate 103 capable of entering a gap between the object W and a transparent window 28 and also withdrawing from the gap. On condition that the shielding plate 103 is closed to cut off irradiation heat from the transparent window 28, the product film is formed by allowing the active gas species of NF3 gas to react with a native oxide film on the object under the low-temperature condition. After that, upon closing the shielding plate 103, the native oxide film is removed by applying heat irradiated from a heating lamp 36 to the product film through the transparent window 28.Type: GrantFiled: October 31, 2007Date of Patent: March 19, 2013Assignee: Tokyo Electron LimitedInventors: Yasuo Kobayashi, Masao Yoshioka

Patent number: 8388397Abstract: The present invention provides a liquid crystal cell manufacturing device and a method thereof. The liquid crystal cell manufacturing device includes a pre-alignment vacuum chamber, a vacuum lamination chamber and a sealant curing chamber. The pre-alignment vacuum chamber includes a comb-type transferring system for aligning a first substrate with a second substrate and sending them into the vacuum lamination chamber. The vacuum lamination chamber uses a lamination device to laminate the first substrate and the second substrate into a substrate assembly under a nearly vacuum status, and then uses a transferring device to send the substrate assembly to the sealant curing chamber. The sealant curing chamber uses at least one UV spot light source to move above the substrate assembly and irradiate a surface of the substrate assembly to cure at least one sealant in the substrate assembly, and thereby complete manufacture of liquid crystal cells of liquid crystal panels.Type: GrantFiled: November 22, 2010Date of Patent: March 5, 2013Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventor: Yun Wang

Patent number: 8382938Abstract: A gate valve cleaning method that can clean a gate valve that brings an atmospheric transfer chamber and an internal pressure variable transfer chamber that transfer a substrate into communication with each other or shuts them off from each other without bringing about a decrease in the throughput of a substrate processing system. Before the gate valve brings the atmospheric transfer chamber and the internal pressure variable transfer chamber into communication with each other, the pressure in the internal pressure variable transfer chamber is increased so that the pressure in the internal pressure variable transfer chamber can become higher than the pressure in the atmospheric transfer chamber.Type: GrantFiled: September 23, 2011Date of Patent: February 26, 2013Assignee: Tokyo Electron LimitedInventors: Tsuyoshi Moriya, Hiroyuki Nakayama, Keisuke Kondoh, Hiroki Oka
