    摘要: A method and system for improved planar deprocessing of semiconductor devices using a focused ion beam system. The method comprises defining a target area to be removed, the target area including at least a portion of a mixed copper and dielectric layer of a semiconductor device; directing a precursor gas toward the target area; and directing a focused ion beam toward the target area in the presence of the precursor gas, thereby removing at least a portion of a first mixed copper and dielectric layer and producing a uniformly smooth floor in the milled target area. The precursor gas causes the focused ion beam to mill the copper at substantially the same rate as the dielectric. In a preferred embodiment, the precursor gas comprises methyl nitroacetate. In alternative embodiments, the precursor gas is methyl acetate, ethyl acetate, ethyl nitroacetate, propyl acetate, propyl nitroacetate, nitro ethyl acetate, methyl methoxyacetate, or methoxy acetylchloride.

    摘要: A microscopic metallic structure is produced by creating or exposing a patterned region of increased conductivity and then forming a conductor on the region using electrodeposition. In some embodiments, a microscopic metallic structure is formed on a substrate, and then the substrate is etched to remove the structure from the substrate. In some embodiments, a focused beam of gallium ion without a deposition precursor gas scans a pattern on a silicon substrate, to produce a conductive pattern on which a copper structure is then formed by electrochemical deposition of one or more metals. The structure can be freed from the substrate by etching, or can used in place. A beam can be used to access an active layer of a transistor, and then a conductor can be electrodeposited to provide a lead for sensing or modifying the transistor operation while it is functioning.

    摘要: A method for controlling chemical dry etching to improve smoothness of an etched surface is disclosed. Ions are implanted into a surface to form a volatilizable compound at a temperature low enough to avoid, reduce, or eliminate formation of three-dimensional structures of the volatilizable compound that might create the roughness at an etched surface of the volatilizable compound. The ions are applied in a sufficient energy to penetrate to a predetermined depth of material that is to be removed from the surface in an etching cycle, and in a sufficient dosage to achieve full formation of the volatilizable compound. The surface of the volatilizable compound is exposed to a gas composition for a time duration sufficient to completely etch the volatilizable compound.

    摘要: A working method of performing beam assist deposition or beam assist etching of a sample comprises irradiating a focused charged particle beam onto a region of the sample, and blowing a predetermined gas through a gas blowing nozzle toward the sample region while the focused charged particle beam passes through a passage in a side portion of the gas blowing nozzle and irradiates the sample region. The passage may be a slot provided in the side portion of the gas blowing nozzle such that the focused charged particle beam passes through an inside of the slot. The slot terminates at one end near a tip of the gas blowing nozzle, and the one end of the slot terminates at and opens into the interior of the gas blowing nozzle.

    摘要: A method for fabrication of microscopic structures that uses a beam process, such as beam-induced decomposition of a precursor, to deposit a mask in a precise pattern and then a selective, plasma beam is applied, comprising the steps of first creating a protective mask upon surface portions of a substrate using a beam process such as an electron beam, focused ion beam (FIB), or laser process, and secondly etching unmasked substrate portions using a selective plasma beam etch process. Optionally, a third step comprising the removal of the protective mask may be performed with a second, materially oppositely selective plasma beam process.
