An ion beam milling system and method for electron microscopy specimen preparation is provided and is useful for the preparation for analysis by either TEM or SEM of semiconductors, metals, alloys, ceramics, and other inorganic materials. In one embodiment, a system and process are provided for the preparation of specimens for analysis by transmission electron microscopy including a specimen processing chamber, at least two ion beam generators, and a specimen support or holder. An ion beam masking member is secured to a surface of the specimen and the specimen is milled. Preferably, the system also includes the ability to view the progress of the milling operation and may include an imaging device such as a light microscope which permits monitoring of the area of interest on a specimen as the specimen is milled.

Ion beam milling system and method for electron microscopy specimen preparation

A side-entry specimen holder for transmission electron microscopy is provided. The specimen holder is capable of rotating a specimen and tilting it in two axes. The specimen, when mounted in the holder, can be tilted in the plus/minus direction of the X-axis, the plus/minus direction of the Y-axis, and simultaneously have the ability of 360&deg; rotation in the axis of the electron beam to permit alignment of microstructural features of the specimen for optimal viewing and analysis.

An apparatus and process for the etching and coating of samples in a single vacuum chamber, thus minimizing handling and transfer of the samples is provided. The apparatus includes a sealed chamber and a vacuum pump for forming and maintaining a vacuum in the chamber, a first ion gun positioned in the chamber to etch a sample, a sputtering target in the chamber, and at least one additional ion gun positioned in the chamber to cause material from the target to be directed onto the sample.

Apparatus for etching and coating sample specimens for microscopic

An apparatus and a specimen holder adapted to permit simultaneous two-sided ion beam milling at very low angles of beam incidence, down to 0.degree., from both sides of the specimen is provided and includes a specimen holder for two-sided ion beam milling and a pedestal having at least one extending specimen support arm adapted to engage a peripheral edge of a specimen. The specimen is secured to the at least one specimen support arm, preferably, so as to permit ion beams to be directed at the first and second major surfaces of the specimen simultaneously at very low angles of incidence down to 0.degree.. Both rapid milling as well as a reduction in artifacts provide high quality specimens for transmission electron microscopy analysis.
