    Abstract: In one embodiment, electron-beam or ion-beam induced etching of a work piece at a temperature below room temperature in a precursor gas is disclosed. The beam-induced etching may use a work piece maintained at a temperature near the boiling point of a precursor material, e.g. NF 3 , but the temperature is sufficiently high to desorb reaction byproducts.
    In another embodiment, NF 3 is used for generating a ionization cascade to amplify the number of secondary electrons for detection in a charged particle beam system for processing a work piece.

    Abstract: An environmental cell for a charged particle beam system allows relative motion between the cell mounted on an X-Y stage and the optical axis of the focusing column, thereby eliminating the need for a sub-stage within the cell. A flexible cell configuration, such as a retractable lid, permits a variety of processes, including beam-induced and thermally-induced processes. Photon yield spectroscopy performed in a charged particle beam system and using gas cascade amplification of the photoelectrons allows analysis of material in the cell and monitoring of processing in the cell. Luminescence analysis can be also performed using a retractable mirror.

    Abstract: Material is deposited in a desired pattern by spontaneous deposition of precursor gas at regions of a surface that are prepared using a beam to provide conditions to support the initiation of the spontaneous reaction. One the reaction is initiated, it continues in the absence of the beam at the regions of the surface at which the reaction was initiated.

    Abstract: An improved microcalorimeter-type energy dispersive x-ray spectrometer provides sufficient energy resolution and throughput for practical high spatial resolution x-ray mapping of a sample at low electron beam energies. When used with a dual beam system that provides the capability to etch a layer from the sample, the system can be used for three-dimensional x-ray mapping. A preferred system uses an x-ray optic having a wide-angle opening to increase the fraction of x-rays leaving the sample that impinge on the detector and multiple detectors to avoid pulse pile up.

    Abstract: An improved method for laser processing that prevents material redeposition during laser ablation but allows material to be removed at a high rate. In a preferred embodiment, laser ablation is performed in a chamber (140, 501) filled with high pressure precursor (etchant) gas so that sample particles ejected during laser ablation will react with the precursor gas in the gas atmosphere of the sample chamber. When the ejected particles (108) collide with precursor gas particles (202), the precursor is dissociated, forming a reactive component that binds the ablated material. In turn, the reaction between the reactive dissociation by-product and the ablated material forms a new, volatile compound (204) that can be pumped away in a gaseous state rather than redepositing onto the sample (104).
