    Abstract: A method and apparatus are provided to control the radial or non-radial temperature distribution across a substrate during processing to compensate for non-uniform effects, including radial and angular non-uniformities arising from system variations, or process variations, or both. The temperature is controlled, preferably dynamically, by flowing backside gas differently across different areas on a wafer supporting chuck to vary heat conduction across the wafer. Backside gas flow, of helium, for example, is dynamically varied across the chuck to control the uniformity of processing of the wafer. Ports in the support are grouped, and gas to or from the groups is separately controlled by different valves responsive to a controller that controls gas pressure in each of the areas to spatially and preferably dynamically control wafer temperature to compensate for system and process non-uniformities.

    Abstract: To determine the profile of an integrated circuit structure, a signal is measured off the structure with a metrology device. The measured signal is compared to signals in a virtual profile library. The comparison is stopped if matching criteria are met. A subset of a virtual profile data space is determined when the matching criteria are not met. The subset is determined using profile data space associated with the library. A virtual profile signal of the subset is selected. Virtual profile shape/parameters are determined based on the virtual profile signal. A difference is calculated between the measured and virtual profile signals. The difference is compared to virtual profile library creation criteria. If the criteria are met, then the structure is identified using virtual profile data, which includes the virtual profile shape/parameters, associated with the virtual profile signal. Or, if the criteria are not met, then a corrective action is applied.

    Abstract: A method of refining a virtual profile library includes obtaining a reference signal measured off a reference structure on a semiconductor wafer with a metrology device. A best match is selected of the reference signal in a virtual profile data space. The virtual profile data space has data points with specified accuracy values. The data points represent virtual profile parameters and associated virtual profile signals. The virtual profile parameters characterize the profile of an integrated circuit structure. The best match being a data point of the profile data space with a signal closest to the reference signal. Refined virtual profile parameters are determined corresponding to the reference signal based on the virtual profile parameters of the selected virtual profile signal using a refinement procedure.

    Abstract: A processing system is disclosed, having an electron beam source chamber that excites plasma to generate an electron beam, and an ion beam source chamber that houses a substrate and also excites plasma to generate an ion beam. The processing system also includes a dielectric injector coupling the electron beam source chamber to the ion beam source chamber that simultaneously injects the electron beam and the ion beam and propels the electron beam and the ion beam in opposite directions. The voltage potential gradient between the electron beam source chamber and the ion beam source chamber generates an energy field that is sufficient to maintain the electron beam and ion beam as a plasma treats the substrate so that radio frequency (RF) power initially applied to the processing system to generate the electron beam can be terminated thus improving the power efficiency of the processing system.

    Abstract: A method of generating a signal representing with an ion energy analyzer for use in determining an ion energy distribution of a plasma. The ion energy analyzer, used for determining an ion energy distribution of a plasma, includes a first grid and a second grid that is spaced away from and electrically isolated from the first grid. The first grid forms a first surface of the ion energy analyzer and is positioned to be exposed to the plasma. The first grid includes a first plurality of openings, which are dimensioned to be less than a Debye length for the plasma. A voltage source and an ion current meter are operably coupled to the second grid, the latter of which is configured to measure an ion flux onto the ion collector and to transmit a signal that represents the measured ion flux. The method includes selectively and variably biasing the second grid relative to the first grid.
