KLA / TENCOR RS-55TCA is a wafer testing and metrology equipment used in semiconductor manufacturing. It provides wafer-level measurement and analysis, and can be used to assess a wide range of device parameters such as surface shape, electrode width, size, and geometrical characteristics. The unit is capable of analyzing features of up to 0.8 μm in size, making it an excellent tool for precise testing of sub-micron devices. A major advantage of KLA RS55TCA is its ability to utilize time-resolved measurement techniques to assess sensitive device properties with high accuracy. This is enabled by the system's powerful Phase-Shift Interferometer (PSI) sensor, which works in tandem with a real-time differential signal processor. This combination is able to detect minute changes between observations taken over short time intervals, enabling excellent accuracy in measurement results and faster throughput of testing compared to conventional techniques. The unit is composed of several components. A robotic end-effector is capable of positioning the wafer for scanning across the PSI sensor in a linear motion or a point-based raster scan. A semiconductor belt conveyor and wafer platform provide a secure platform for the wafer during testing. An optical microscope head enables high-resolution magnified imaging of the wafer surface and subsequent data analysis. Finally, TENCOR RS-55 TCA includes an integrated control and analysis unit consisting of a personal computer, an integrated motor control unit, and associated software. This unit is powerful enough to control the wafer positions and process the data from the PSI sensor to produce high-quality results for measurement and analysis. Overall, RS 55 TCA is a powerful wafer inspection and metrology tool that provides excellent accuracy and fast throughput thanks to its time-resolved measurement machine. Its versatile capabilities and integrated control systems make it an ideal choice for advanced semiconductor research and development.
