Used GATAN 691 #293752323 for sale

GATAN 691 is a high-tech ion milling equipment designed to facilitate precision surface modification of a wide array of materials through a process known as ion milling. This system takes advantage of the "dry" precision etching technology of gallium ion milling to enable exceptional control over material surfaces and three-dimensional (3D) features. 691 unit is designed to permit high-speed milling of semiconductor or insulating materials including silicon, aluminum, carbon, silicon dioxide, silicon nitride, and tungsten. This machine has an ultra-low-energy ion source capable of delivering focused ion beams with energies ranging from 0.5 keV to 10 keV. Additionally, with its powerful 20 W gallium ion source, GATAN 691 can deliver very high-quality milling outcomes with minimal collateral damage, making it ideal for materials where high fidelity is particularly valued. Furthermore, its robust control tool allows for precise changes in angle and distance when processing, making it useful for creating custom features and high-precision etching. 691 has several advantageous features including its high-resolution stage movements, which make it suitable for surface patterning with feature sizes as small as 100 nm; its optical systems for viewing and real-time surface assessment; and its integrated load-lock, which maintains a vacuum to avoid post-processing oxidation. It also includes isolated safety systems that keep personnel and the equipment safe, as well as an ultra-low-pressure resistive heating asset and a closed-zoom-lens configuration designed for imaging. The user friendly interface of GATAN 691 features an intuitive graphical user interface (GUI) for process recipe setup, control and monitoring, flexible model automation module with IQ/OQ validation, and a remote access option for enhanced operational efficiency. It also includes a comprehensive real-time diagnostics module, enabling users to troubleshoot and resolve equipment issues promptly. In addition to these features, 691 includes a bench top ion beam analyzing system, which supports a range of energy-filtered imaging and spectroscopic techniques. The unit also comes with a powerful turbo pump support and a five-station pallet changer for increased throughput and processing simulation. Finally, GATAN 691 can be adapted to a range of applications, from lithography to sample and specimen preparation. Overall, 691 is an advanced ion-milling machine designed to enable production-scale, surface-modification processes with unprecedented speed and control. With its combination of low-energy ion technology and controlled stage movements, GATAN 691 provides a reliable and efficient tool for fabricating high-precision features and surfaces.
