Abstract: Example methods and systems for validation-based service request handling are described. In one example, a computer system may obtain, from a management entity, configuration information specifying a unicast service address associated with a service node capable of providing a network service. In response to detecting a service request from the virtualized computing instance, the computer system may generate a modified service request that (a) is destined for the unicast service address and (b) includes a validation identifier (ID) associated with the virtualized computing instance. The modified service request may be forwarded towards the service node to cause the service node to perform validation based on the validation ID to determine whether to provide the network service. In response to detecting a service response from the service node, the service response, or a modified service response, may be forwarded towards the virtualized computing instance.

Abstract: The present disclosure relates to methods of processing a semiconductor substrate in a processing chamber, such as a chemical vapor deposition chamber. The chemical vapor deposition chamber includes a spindle mechanism that cooperates with one or more carrier ring forks to move the semiconductor substrate from one station to another station. The methods include monitoring one or more spindle operation parameters and carrying out one or more maintenance steps on the spindle mechanism based on the results of monitoring the one or more spindle operation parameters. The monitored spindle operation parameters provide an indication of undesirable vibration of the semiconductor substrates in the processing chamber. The vibration of the semiconductor substrates in the processing chamber is undesirable because it promotes generation of unwanted particles that deposit onto a surface of the semiconductor substrate.
