Used KLA / TENCOR Alpha Step 500 #293665099 for sale

KLA / TENCOR Alpha Step 500 is a wafer testing and metrology equipment designed to precisely measure the flatness, thickness, and alignment of thin wafers used in the semiconductor industry. The system employs an automated telescopic visioning unit, which utilises optical microscopy, to measure the profile of the wafer. This enables the machine to reliably produce highly accurate electrical and motion metrology results. KLA Alpha Step 500 comprises a mainframe, powered by a Windows based graphical user interface (GUI), that receives and manages all the data from the tool. It provides an outwards facing control panel with LCD display, enabling the user to control the asset remotely. At its core, the mainframe consists of hardware such as precision motion stages, inspection lamps, filters and linear scales. Motion stages are used to provide highly accurate and controlled movement of the wafer, while the optical microscope provides the capability to see and measure the smaller features of the wafer. This mainframe is paired with computer vision algorithms to gather and evaluate data from the microscope. The algorithms interpret the data, and post-processes it before providing it to the mainframe for further analysis. This analysis can then be used to produce a detailed report of the wafer's properties. TENCOR ALPHASTEP 500 delivers results faster than traditional methods, with high levels of accuracy and repeatability. In addition, it is cost-effective, and easy to operate and maintain. This makes it an ideal choice for wafer testing and metrology in the semiconductor industry.
