  • Patent number: 10734246
    Abstract: A chamber door, such as an etch chamber door may be heated during etch processing to, e.g., prevent etching by-products from adhering to the etch chamber door. Such heating of the etch chamber door, however, can impact the processing parameters and result in non-uniform processing, such as non-uniform etching characteristics across a semiconductor wafer, for instance. An insulator, such as an insulating film covering surfaces of the heated door, can reduce or eliminate transmission of heat from the door to a work piece such as a semiconductor wafer and this reduce or eliminate the non-uniformity of the process results.

  • Patent number: 10664551
    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.

  • Patent number: 10616348
    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.
