Web1 nov. 1997 · Ion milling with a focused ion beam (FIB) is a potential method for making micromolds, which will then be the primary elements in the mass production of micro- or mini-objects by embossing or injection molding. The challenge lies in controlling the ion milling to produce cavities with predefined, arbitrary geometric cross-sections. This work … WebThe focused ion beam has become a powerful tool for site-specific 3D imaging of sub-micron features in a sample. In this FIB tomography technique, the sample is sequentially milled using an ion beam … WebIon beam intermittent irradiation: Standard function: Swing angle: ±15°, ±30°, ±40° Flat Milling; Milling area: φ32 mm: Maximum sample size: φ50 × 25(H) mm: Sample moving range: X 0 to +5 mm: Ion beam intermittent irradiation: Standard function: Rotation speed: 1 rpm, 25 rpm: Tilt: 0 to 90° dog face on pajama bottoms
