Used KLA / TENCOR Zeta 20 #293779066 for sale

KLA / TENCOR Zeta 20 is an advanced wafer testing and metrology equipment designed for precise quality inspection of semiconductor wafers. It is powered by a patented Non-contact Optical Rotary Motor (NORM) Technology, and is capable of undertaking efficient, high-speed measurements on wafer surfaces and edges. The system can detect feature sizes down to 0.2 µm, enabling the user to control and monitor wafer formation during fabrication and test for contamination. The unit uses a highly efficient and precise optical positioning device to rotate the wafer during inspection. This allows for accurate measurements of features length and width. The motor is capable of providing up to 400 series of measurements multiple times on two sides of a wafer at any given point. It also includes an enhanced light-emitting diode (LED) array to provide uniform illumination of the target surface for accurate imaging. The machine also includes a precise filtering stage, allowing for accurate detection of key parameters such as wafer shape and surface roughness. All results can be viewed on the tool's user-friendly graphical display. The asset is engineered to be highly reliable, and is capable of producing repeatable results. It is also designed to interact with standard metrology systems, allowing for the transfer of data between different instruments. The model also has a range of automated functions, including contrast change detection and automatic alarm setting. This helps to increase efficiency and improve accuracy by automatically notifying the user when detected values fall outside the specified range. KLA Zeta 20 equipment is a powerful and reliable tool for semiconductor wafer inspection and metrology. Its accuracy and automation functions help to increase productivity and improve quality control of semiconductor devices.
