    摘要: A focused ion beam having a cross section of submicron diameter, a high ion current, and a narrow energy range is generated from a target comprised of particle source material by laser ablation. The method involves directing a laser beam having a cross section of critical diameter onto the target, producing a cloud of laser ablated particles having unique characteristics, and extracting and focusing a charged particle beam from the laser ablated cloud. The method is especially suited for producing focused ion beams for semiconductor device analysis and modification.

    摘要: A process for etching multiple layers on a substrate 25 in an etching chamber 30 and cleaning a multilayer etchant residue formed on the surfaces of the walls 45 and components of the etching chamber 30. In multiple etching steps, process gas comprising different compositions of etchant gas is used to etch layers on the substrate 25 thereby depositing a compositionally variant etchant residue inside the chamber 30. In one cleaning step, a first cleaning gas is added to the process gas to clean a first residue or to suppress deposition of the first residue onto the chamber surfaces. In a second cleaning step, another residue composition is cleaned off the chamber surfaces using a second cleaning gas composition.

    摘要: An apparatus for adaptive self-aligned dual patterning and method thereof. The method includes providing a substrate to a processing platform configured to perform an etch process and a deposition process and a metrology unit configured for in-vacuo critical dimension (CD) measurement. The in-vacuo CD measurement is utilized for feedforward adaptive control of the process sequence processing platform or for feedback and feedforward adaptive control of chamber process parameters. In one aspect, a first layer of a multi-layered masking stack is etched to form a template mask, an in-vacuo CD measurement of the template mask is made, and a spacer is formed, adjacent to the template mask, to a width that is dependent on the CD measurement of the template mask.

    摘要: A substrate 20 in a process chamber 42 is processed at process conditions suitable for processing a layer 30 on the substrate 20, the process conditions comprising one or more of process gas composition and flow rates, power levels of process gas energizers, process gas pressure, and substrate temperature. The intensity of a reflected light beam 78 reflected from the layer 30 on the substrate 20 is measured over time, to determine a measured waveform pattern. The measured waveform pattern is compared to a pretetermined characteristic waveform pattern, and when the two waveform patterns are similar or substantially the same, the process conditions are changed to change a rate of processing or a process selectivity ratio of the layer 30 on the substrate 20 before the entire layer 30 is completely processed.

    摘要: A method and apparatus for vacuum processing of a workpiece, the apparatus including a flow equalizer disposed in a vacuum processing chamber between a workpiece support pedestal and a pump port located in a wall of the vacuum processing chamber. In an embodiment, the flow equalizer has a first annular surface concentric about the workpiece support pedestal to provide conductance symmetry about the workpiece support even when the pump port is asymmetrically positioned within the vacuum processing chamber. In an embodiment, the flow equalizer has a second annular surface facing a lower surface of the workpiece support pedestal to restrict conductance as the flow equalizer is moved is response to a chamber pressure control signal. In an embodiment, the apparatus for vacuum processing of a workpiece includes tandem vacuum processing chambers sharing a vacuum pump with each tandem chamber including a flow equalizer to reduce cross-talk between the tandem chambers.
