  • Publication number: 20180151422
    Abstract: A method includes forming a first conductive feature in a first dielectric layer. An etch stop layer is formed over the first dielectric layer. A second dielectric layer is formed over the etch stop layer. The second dielectric layer and the etch stop layer are patterned to form an opening, where a portion of the etch stop layer is interposed between a bottom of the opening and the first conductive feature. The portion of the etch stop layer is sputtered to extend the opening toward the first conductive feature and form an extended opening, where the extended opening exposes the first conductive feature. The extended opening is filled with a conductive material to form a second conductive feature in the second dielectric layer.

  • Publication number: 20180144949
    Abstract: A representative method for selective radical-component etching of exposed nitride-containing material comprises the steps of: disposing a substrate in an etch processing region; producing a plasma in a plasma region; flowing a radical component of the plasma into the etch processing region while substantially excluding charged ions of the plasma from entering the etch processing region; flowing an unexcited gas into the etch processing region; and etching an exposed nitride-containing material with reaction products of the radical component of the plasma and the unexcited gas. Etch selectivity for nitride-containing material may be more than about 10 times that of oxide-containing material. In a representative aspect, etching proceeds without producing, or otherwise substantially reducing, residue on the surface of the substrate.

The semiconductor manufacturing tool includes push pins in a chuck and an edge ring over the chuck. The push pins are configured to hold a wafer, and are operable to vary a height of the wafer with respect to the chuck. The edge ring has a first width at a base proximate the chuck, and a second width at a point distal the chuck. The first width is greater than the second width. A distance from the wafer to the edge ring varies when the push pins vary the height of the wafer with respect to the chuck.

  • Publication number: 20180077245
    Abstract: Systems and methods for providing and supporting multiple Intelligent Platform Management Interface (IPMI) serial over local area network (SOL) sessions in a management controller. The system includes a management controller used to manage multiple nodes, and at least one remote computing device connected to the management controller via a local area network (LAN). In operation, the management controller configures multiple serial ports for the nodes, so the management controller is communicatively connectable to each of the nodes respectively via one of the serial ports. When the management controller receives a SOL request from the remote computing device to establish a SOL session to access a specific node, the management controller may accordingly establish the SOL session between the specific node and the remote computing device sending the SOL request. Thus, the management controller may support multiple SOL sessions, and may store information of each of the SOL sessions independently.

  • Publication number: 20180026854
    Abstract: Certain aspects direct to systems and methods for providing an intuitive user interface (UI) for device or vendor independent network switch management via a management controller. The management controller is communicatively connected to a network switch through a Simple Network Management Protocol (SNMP) interface. The management controller provides a web UI. When a remote computing device request the web UI, the management controller sends the web UI to the remote computing device. Thus, a user at the remote computing device may upload the parsed information of the MIB file to the management controller through the UI. The management controller then processes the parsed information of the MIB file, and displays the processed parsed information in a hierarchical organization through the UI. Then the management controller establishes a communication between the management controller and the network switch through the SNMP interface based on the parsed information of the MIB file.

  • Publication number: 20180026830
    Abstract: Certain aspects direct to systems and methods for network switch management via a management controller using a management information base (MIB) to JavaScript Object Notation (JSON) parser. At a computing device, an administrator provides a MIB file corresponding to a network switch to be managed. Then the administrator utilizes a parser application to parse the MIB file at the computing device to retrieve Object Identifiers (OIDs) from the MIB file, and then converts the OIDs to JSON objects, in order to generate parsed information of the MIB file including the JSON objects. Thus, the administrator may use a browser to access a web user interface at a management controller to upload the parsed information of the MIB file to the management controller. The management controller may then manage and configure the network switch through a Simple Network Management Protocol (SNMP) interface based on the parsed information of the MIB file.

    Abstract: Certain aspects direct to systems and methods for device or vendor independent network switch management on a management controller. The management controller is communicatively connected to a network switch through a Simple Network Management Protocol (SNMP) interface. The management controller receives parsed information of a management information base (MIB) file corresponding to the network switch, and establishes a communication between the management controller and the network switch through the SNMP interface based on the parsed information of the MIB file, in which the management controller functions as a client and the network switch functions as a server of the communication. Then the management controller receives an input to manage and configure the network switch, and manages and configures the network switch via the communication through the SNMP interface based on the input and the parsed information of the MIB file.
