Stage
Both instruments can accommodate wafers up to 2” or other device platforms in a high-vacuum environment. The high accuracy five-axis stage has a range of 2”, and provides computer control and automation of all directions of movement.
Gas Deposition
Multiple gas injectors can be installed for material deposition in conjunction with either electron or ion beam pattern definition. Electron beam-induced deposition offers the advantage that the the deposited material is not sputtered, and that no gallium ions are implanted. The Gas Injection System (GIS) also provides enhanced etching capability for high aspect ratio drilling with minimal re-deposition, preferential etching of cross-section surfaces prior to SEM imaging, and rapid milling of TEM sections. Up to four self-contained GIS beam chemistries can be installed at the workstation, allowing the precursor material to be contained entirely within the vacuum system for simple, flexible, and safe operation. Currently, our instruments are equipped with platinum deposition GIS. It should be noted that the Quanta 3D system can be operated in environmental mode at ambient conditions, which is of particular interest for SEM imaging at biological specimen.
