Used KLA / TENCOR Alpha Step 200 #293792691 for sale

KLA / TENCOR Alpha Step 200 is an advanced wafer testing and metrology equipment that is designed for production-level testing and analysis of microelectronic devices and circuits. The system offers a wide range of integrated capabilities for wafer, die, and film characterization, die attach and flip chip bond inspection, and defect review. KLA ALPHASTEP 200 utilizes an illuminating laser scanning microscope to capture high-resolution images of the sample surface. These images are analyzed to capture key metrics such as surface strain, step-height, roughness, and defect characteristics. The integrated defect review feature makes use of specialized software to accurately pinpoint and classify features on the surface of the wafer and identify potential flaws in device fabrication or assembly. In addition to its imaging capabilities, TENCOR ALPHA-STEP 200 contains several advanced metrology tools that offer precise physical characterization. It features a sliding surface profilometer that provides 3D measurements of sample height, surface mapping and wafer surface stress. The included dielectric constant measurement unit is used to measure the thickness of thin-film dielectric layers. KLA / TENCOR ALPHASTEP 200 also contains a specialized bond inspection feature. This allows for ultra-high resolution imaging of solder die attach and flip chip bond components. The bond inspection machine is designed to detect defects such as bridging, voiding, and misalignment in the bonding process, which can help prevent costly re-work or scrap. KLA ALPHA-STEP 200 is a versatile platform for production testing and characterization of semiconductor devices and components. It offers reliable and accurate measurement and imaging capabilities, along with defect review and bond inspection features for comprehensive wafer analysis. The tool is capable of analyzing wafers up to 200 mm in diameter and measuring features down to 25 nm in size. The asset is also able to scan up to 1,600 die per hour, enabling rapid in-line testing and defect review. Overall, TENCOR ALPHASTEP 200 is a powerful tool for production-level testing, analysis, and optimization of microelectronic devices and circuits.
