A system and method for servicing secure data object management aware applications using a cloud-based host environment and a local secure container. The cloud-based host environment creates a controlled digital object from a master digital object, and activates a tether associated with the controlled digital object. The tether includes an access permission, and optionally an operation permission (e.g., view, delete, store, edit, and copy) and a command (e.g., timeout, destroy). The controlled digital object is stored to an isolated storage of the secure container. The tether contents control access and manipulation of the controlled digital object. Certain conditions (e.g., timeout period reached, anomalous data access pattern detected), cause the controlled digital object to be destroyed and/or the tether to be inactivated. In accordance with applicable law, the cloud-based host environment utilizes the tether to detect, identify, and/or thwart unauthorized host environments in possession of the controlled digital object.

Liquid material is precisely dispensed to a semiconductor processing tool utilizing closed loop control. In one embodiment, CMP slurry material of known density is supplied from a reservoir/mixing vessel to a dispense module. The dispense module also receives a flow of an inert gas through a gas supply valve. Positive pressure arising within the dispense module due to the inert gas flow causes an outflow of slurry from the dispense module to the CMP platen. The rate of flow of the slurry to the CMP platen over time is determined by monitoring the change (decline) in weight of the filled dispense module. In a similar manner, variation in the rate of flow of slurry over time may be detected by monitoring variation in changes in weight of the filled dispense module over time. A regulator structure in electronic communication with the dispense module and with the gas supply valve receives first signals at different time points indicating the weight change of the dispense module. In response, the regulator structure communicates a second signal to the gas supply valve, reflecting an appropriate change in the rate of flow of CMP slurry material to the platen. This second signal causes the gas supply valve to vary the flow of inert gas to the dispense module in order to control changes in the flow rate of the slurry.

A retaining ring has an inner core of a first material and an outer layer of a second, different material that is deposited on the first material. The outer layer can be deposited by spraying, e.g., by powder coating, and can be a polymer, e.g., polyetheretherketone.

A load lock chamber includes a chamber body having an aperture to allow a substrate to be transferred into or out of the chamber. The load lock chamber is configurable in several configurations, including a base configuration for providing a transition between two different pressures, a heating configuration for heating the substrate and providing a transition between two different pressures, and a cooling configuration for cooling the substrate and providing a transition between two different pressures. Various features of the chamber configurations help increase the throughput of the system by enabling rapid heating and cooling of substrates and simultaneous evacuation and venting of the chamber, and help compensate for thermal losses near the substrate edges, thereby providing a more uniform temperature across the substrate.

Multi-function chamber for a substrate processing system

A method of transferring and processing a substrate in an evacuable chamber which is located adjacent a process chamber and back-to-back process chambers, and other combinations of evacuable chambers and process chambers. The method includes the use of various isolation valves disposed between adjacent chambers, as well as gas flow valves and vacuum valves. By controlling the positions of the valves, the flow of gas to and from the different chambers can be controlled.

Method of controlling gas flow in a substrate processing system

A substrate processing system can include an evacuable chamber adjacent a process chamber and back-to-back process chambers, or other combinations of evacuable chambers and process chambers. The processing system includes various isolation valves disposed between adjacent chambers, as well as gas flow valves and vacuum valves. A controller controls the respective positions of the various gas flow valves and vacuum valves depending, in part, on whether the various isolation valves are in their open or sealed positions. By controlling the positions of the valves, the flow of gas to and from the different chambers can be controlled, for example, to help maximize throughput, increase efficiency, and reduce the likelihood of cross-contamination between chambers.
