  • Publication number: 20200249263
    Abstract: Embodiments described herein relate to methods and tools for monitoring electrostatic chucking performance. A performance test is performed that requires only one bowed substrate and one reference substrate. To run the test, the reference substrate is positioned on an electrostatic chuck in a process chamber and the bowed substrate is positioned on the reference substrate. A voltage is applied from a power source to the electrostatic chuck, generating an electrostatic chucking force to secure the bowed substrate to the reference substrate. Thereafter, the applied voltage is decreased incrementally until the electrostatic chucking force is too weak to maintain the bowed substrate in flat form, resulting in dechucking of the bowed wafer. By monitoring the impedance of the chamber during deposition using a sensor, the dechucking threshold voltage can be identified at the point where the impedance of the reference substrate and the impedance of the bowed substrate deviates.

    Abstract: Techniques for efficient roaming of clients between access points (APs) of a wireless data communications network are described. A first AP can receive a request for the first client to join the network. The request can specify a unique identifier for the first client. An identifier for a second AP can be determined by processing the unique identifier for the first client using a predefined hash function. A network address of the second AP can be determined using the determined identifier for the second AP. The first AP can transmit a request to the determined network address of the second AP to query for network state information corresponding to the first client, and upon receiving a pairwise master key (PMK) associated with the first client, can authenticate the first client to join the network.
