Used KLA / TENCOR Alpha Step 200 #9363076 for sale

KLA / TENCOR Alpha Step 200 is a wafer testing and metrology equipment that enables precise and efficient measurement of nanomechanical properties on semiconductor wafers. This system has several advanced features that make it highly accurate and reliable. KLA ALPHASTEP 200 comes with both a horizontal (x- and y-axis) and a vertical (z-axis) stepper scanner, providing precise and repeatable alignment of the test surface to the measurement head and wafer. This ensures accurate measurements of topography, critical dimensions, and surface topologies. It uses two scanning stages, one for the testing head and one for the wafer. This is useful for capturing fine details, such as nanoscale features, with high precision. TENCOR ALPHA-STEP 200 also includes a unique optical square offset alignment unit, which combines optical square configurability with an automated stage, resulting in a much more precise alignment than manual methods. This improved accuracy results in sharper images, which can then be analyzed to extract full 3D maps of the surface features. The machine is equipped with several image acquisition capabilities, including standard bright field imaging, bright field with back illumination, and dark field imaging. This allows for accurate measurements of surface topology and other features, such as step heights and sidewall angles. The tool has a wide dynamic range of +/- 30µm, which conveniently caters to various wafer sizes and geometries. ALPHA-STEP 200 also has several software tools, such as SigmaPlot, allowing for fast and precise analysis of images and data. The software provides easy-to-use tools for image manipulation, image filtering, and image comparison. This powerful software suite greatly simplifies data evaluation and analysis. This asset has a compact and efficient design and is able to run unattended for long periods of time, making it an ideal solution for wafer measurement applications. The model is designed to be reliable, with a strong focus on repeatability. TENCOR ALPHASTEP 200 is highly accurate, offering nanoscale precision, and is a great choice for precise wafer testing and metrology.
