Used KLA / TENCOR Alpha Step 200 #293590192 for sale

KLA / TENCOR Alpha Step 200 is a wafer testing and metrology equipment designed for the semiconductor manufacturing process. It provides accurate measurements of critical dimensions and topography of semiconductor substrates for failure analysis, process optimization and development, and process control. This wafer inspection system utilizes non-contact optical metrology technology to perform a variety of measurements. It is capable of measuring CD (critical dimension) across the wafers to as low as 0.3um in resolution. It uses interferometric techniques to provide height, surface roughness, CD uniformity, and profile measurements. Furthermore, KLA ALPHASTEP 200 is a multi-channel unit, allowing users to sequence a variety of measurements on a single substrate or multiple substrates simultaneously. TENCOR ALPHA-STEP 200 also features dual stage automated scanning for high speed, high accuracy measurements of wafer edge profiles. These measurements are used to determine wafer flatness, backside warp, and other characteristics related to wafer edges. Additionally, the machine is capable of detecting defects and anomalies in the wafers, such as particulates, contaminates, or other features that violate process rules. This feature is essential for failure analysis and process optimization. KLA / TENCOR ALPHA-STEP 200 is also equipped with SmartAlign technology, which automatically locates and compensates for substrate deformation, misalignment and bias during the measurement process. This ensures higher level of measurement accuracy and repeatability. Furthermore, the tool can store thousands of measurement programs, allowing users to quickly and easily switch between different test sequences. ALPHASTEP 200 includes a user-friendly wafer inspection software package which helps to simplify the workflow process. This software allows operators to control, configure, analyze, and save the measured data of a particular process. It also allows for customizable reporting and analysis of the results, providing insight into production process performance. KLA Alpha Step 200 is highly automated, saving time for operators. It is designed for use in a 24/7 production environment, offering reliability and performance even in hostile conditions. Its superior accuracy, multi-channel capability, and SmartAlign technology make it an ideal solution for the semiconductor industry.
