Used KLA / TENCOR Alpha Step IQ #193091 for sale

KLA / TENCOR Alpha Step IQ is a wafer testing and metrology equipment designed for the semiconductor industry. The system allows for both on-wafer and stand-alone measurements, enabling users to determine the profile parameters of the wafer. Using a dual-focus optical head, the unit provides fast, high-precision measurements. The optical head measures two planes simultaneously, significantly reducing the measurement time. KLA Alpha Step IQ has a motorized z-stage for vertical movement of the wafer. This allows the machine to make non-contact measurements over a wide range of depths. The tool has a unique combination of optical detectors, featuring both an integrated autocollimator and a non-contact optical microscope. The former provides measurements down to one micron and the latter enables measurements up to several millimeters. TENCOR ALPHASTEP IQ offers three-dimensional measurements of wafer surface, enabling the measurement of height, width, and angle of the profile. The asset is capable of detecting small features, such as narrow ridges or deep valleys. Furthermore, the model has features to support wafer symmetry and profile surface measurements. The user-friendly user interface allows easy operation of ALPHASTEP IQ. The equipment is fully automated and can save up to 500 standard measurements. It also has a powerful analysis software, GraphScheme, which can interpret the collected data in minutes. In addition to wafer testing, KLA / TENCOR ALPHASTEP IQ has metrology features such as extreme ultra-violet (EUV) mask inspection and die-by-die (DBD) inspection. DBD inspection checks each die on the wafer for defects, allowing for more accurate wafer characterization. The EUV mask inspection helps users with photomask manufacturing, as it detects and measures the defects in the mask pattern. Alpha Step IQ is also equipped with several safety features, such as auto-iris monitoring and power safety windows. Its industry-leading design ensures that the system runs with minimal downtime. Overall, KLA ALPHASTEP IQ is a powerful tool for wafer testing and metrology. It offers users enhanced accuracy and speed to increase efficiency and save time.
