Used NANOMETRICS Atlas #9271275 for sale

NANOMETRICS Atlas is a high-precision wafer testing and metrology equipment used in the semiconductor industry. It is designed to provide the highest levels of accuracy and repeatability, enabling users to measure and control features to extremely tight tolerances. Atlas is a non-contact, full-field scanning system that enables measurement of critical dimensions on semiconductor wafers, as well as other wide-area features such as film thickness and resistivity. NANOMETRICS Atlas utilizes a variety of measurement technologies, including white light interferometry (WLI) and video aperture microscopy (VAM). WLI offers imaging of a wide-field of view and sub-nanometer vertical resolution, while VAM has superior lateral and vertical resolution for resolving small-scale features, such as transistors and bondpads. Combined, these technologies allow Atlas to quickly acquire measurements from even the most complex surfaces. NANOMETRICS Atlas also offers a unique combination of non-contact and ultra-high-resolution metrology, with the ability to measure features as small as 1 μm on even the most challenging structures. By supporting various measurement configurations, the unit can be used to measure both flat and highly curved surfaces, such as 3D contours and surface roughness. In addition, Atlas provides 8-inch or 12-inch wafer inspection capabilities alongside its standard 10-inch wafer supported measurements. Along with its advanced measurement capabilities, NANOMETRICS Atlas also features a robust suite of technologies to ensure test quality and repeatability. For example, its automated alignment technology saves time by automatically aligning wafers prior to testing. It also has a built-in vision machine for rapid pre-alignment, and a fully automated sample registration tool for dual-side measurements. Atlas is an ideal choice for precision applications, with its compact design and high accuracy making it suitable for both laboratory and production environments. By providing reliable, consistent measurements in a wide variety of conditions, NANOMETRICS Atlas helps users maintain the highest standards for quality assurance.
