Used KLA / TENCOR 7700 Surfscan #9239241 for sale

KLA / TENCOR 7700 Surfscan is an advanced wafer testing and metrology equipment. It is equipped with a powerful and sensitive optical interferometric surface profiler that can make highly accurate measurements of extremely complex surfaces with nanometer resolution. The system can also be used to perform critical defect detection and analysis. It is capable of measuring the surface topography, thickness, sidewall angle, planarity, and line or feature width with great accuracy. KLA 7700 Surfscan unit can accommodate wafers up to 200mm in diameter and is designed for optimum measurement repeatability. TENCOR 7700 Surfscan utilizes a pairing of interferometric optics and a high resolution CCD camera to analyze a wafer's surface profile, topography, line width, and feature sizes. Through its high-precision scanning technology, the Surfscan is able to capture detailed images of the surface features, which can then be analyzed and compared against pre-defined product specifications. The Surfscan offers a variety of illumination techniques to reduce or eliminate grain noise and surface reflectivity effects, enabling the most accurate measurements. The Surfscan's software is designed to process the surface images and quantitatively measure the 2D profile data with pico-meter precision. It is also capable of analyzing defect sites and identifying them using established tools and algorithms. These measurements can then be used to help determine yield and defect treatments, as well as to help determine design rules for subsequent wafer processing. The Surfscan can interface with a variety of operating systems, making it suitable for a wide range of applications. It is generally considered to be one of the most accurate wafer testing and metrology systems currently available. The machine is designed for reliability and repeatability, ensuring users can rely on getting consistent and accurate results. Finally, 7700 Surfscan is accompanied by a comprehensive user manual and technical support documentation to guide users through the instrument's setup and capabilities.
