    Abstract: Beam-induced deposition decomposes a precursor at precise positions on a surface. The surface is processed to provide linker groups on the surface of the deposit, and the sample is processed to attach nano-objects to the linker groups. The nano-objects are used in a variety of application. When a charged particle beam is used to decompose the precursor, the charged particle beam can be used to form an image of the surface with the nano-objects attached.

    Abstract: An improved apparatus 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).

    Abstract: A system for beam-induced deposition or etching, in which a charged particle or laser beam can be directed to a work piece within a single vacuum chamber, either normally incident or at an angle. Simultaneously with beam illumination of the work piece, a deposition or etch precursor gas is co-injected or premixed with a purification compound and (optionally) a carrier gas prior to injection into the process chamber. The beam decomposes the deposition precursor gas to deposit a film only in areas illuminated by the beam, or decomposes the etch precursor gas to etch a film only in areas illuminated by the beam. Undesired impurities such as carbon in the deposited film are removed during film growth by interaction with adsorbed species on the work piece surface that are generated by interaction of the beam with adsorbed molecules of the film purification compound. Alternatively, the film purification compound can be used to inhibit oxidation of the material etched by the etch precursor gas. By co-injecting or premixing the deposition or etch precursor gas and film purification compound prior to injection, the deposition or etch process may be optimized with respect to growth/etch rate and achievable material purity.

    Abstract: Charged particle beam imaging and measurement systems are provided using gas amplification with an improved imaging gas. The system includes a charged particle beam source for directing a charged particle beam to work piece, a focusing lens for focusing the charged particles onto the work piece, and an electrode for accelerating secondary electrons generated from the work piece irradiation by the charged practice beam, or another gas cascade detection scheme. The gas imaging is performed in a high pressure scanning electron microscope (HPSEM) chamber for enclosing the improved imaging gas including CH 3 CH 2 OH (ethanol) vapor. The electrode accelerates the secondary electrons though the CH 3 CH 2 OH to ionize the CH 3 CH 2 OH through ionization cascade to amplify the number of secondary electrons for detection. An optimal configuration is provided for use of the improved imaging gas, and techniques are provided to conduct imaging studies of organic liquids and solvents, and other CH 3 CH 2 OH-based processes.
