Method and system for producing a neutral beam source is described. The neutral beam source comprises a plasma generation system for forming a first plasma in a first plasma region, a plasma heating system for heating electrons from the first plasma region in a second plasma region to form a second plasma, and a neutralizer grid for neutralizing ion species from the second plasma in the second plasma region. Furthermore, the neutral beam source comprises an electron acceleration member configured to accelerate the electrons from the first plasma region into the second plasma region. Further yet, the neutral beam source comprises a pumping system that enables use of the neutral beam source for semiconductor processing applications, such as etching processes.

Abstract:
A method is provided to cause deformation of a substrate during processing of the substrate. The method comprises supporting a substrate on a substrate support in a vacuum chamber for processing; providing backside gas through inlet ports of each of a plurality of groups of ports lying in a respective plurality of areas across the substrate support to a space between the substrate support and the substrate, each of said areas of the substrate support having at least one backside gas inlet port connected to a supply of backside gas and at least one outlet port connected to a vacuum exhaust system; and separately controlling the pressure of the backside gas at different ones of the ports of the plurality to control separately, in areas around the respective ones of said ports, the local pressure force exerted on the backside of the substrate, by separately dynamically controlling at least one valve affecting gas flow to a port of each of said areas while separately dynamically controlling at least one other valve affecting gas flow from the remaining plurality of ports of each of said areas surrounding said port to which gas is introduced.
Abstract:
A method of using a virtual profile library to determine the profile of an integrated circuit structure includes measuring a signal off the structure with a metrology device. The measurement generates a measured signal. The measured signal is compared to a plurality of signals in at least one library. The comparison is stopped if a matching criteria is met. A subset of a virtual profile data space associated with the virtual profile library is determined when a matching criteria is not met. The subset is determined using profile data space associated with the at least one library. A virtual profile signal of the subset of the virtual profile data space is selected. A virtual profile shape and/or virtual profile parameters are determined based on the virtual profile signal. A difference is calculated between the measured signal and the virtual profile signal. The difference is compared to a virtual profile library creation criteria. If the virtual profile library creation criteria is met, then the structure is identified using virtual profile data, which includes the virtual profile shape and/or the virtual profile parameters, associated with the virtual profile signal. Or, if the virtual profile library creation criteria is not met, then a corrective action is applied.
Abstract:
A plasma processing system includes a processing chamber, a substrate holder configured to hold a substrate for plasma processing, and a gas injection assembly. The gas injection assembly includes a first evacuation port located substantially in a center of the gas injection assembly and configured to evacuate gases from a central region of the substrate, and a gas injection system configured to inject gases in the process chamber. The plasma processing system also includes a second evacuation port configured to evacuate gases from a peripheral region surrounding the central region of the substrate.
