Used KLA / TENCOR / PROMETRIX UV 1250 #9312897 for sale

KLA / TENCOR / PROMETRIX UV 1250 Wafer Testing and Metrology equipment is a powerful tool for inspecting integrated circuits on a single wafer. It is capable of sampling up to 1250 individual locations on each wafer, allowing for highly tailored and accurate analysis across a broad range of parameters. The system's critical component is its ultra-violet light source, which employs both Laser-induced Fluorescence Coupling (LFF) and Autofluorescence Coupling (AFM) technology. Specifically, the unit uses photons of a UV spectrum to excite and examine features and features on the surface of the wafer. Through LFF, the machine is able to determine the thickness of thin insulating layers on the surface. This information is then used to identify the presence or absence of potential defects, so-called 'flaw-free' areas. The tool also offers excellent user-adjustable tropospheric optical options. These settings are used to help reduce surface reflections, optimize on-wafer image contrast, and better quantify features on the wafer. Meanwhile, the automated optical setup allows rapid optimization of the illumination angle and working distance, so that only minimal adjustment to the optical elements is required for optimal performance over the entire surface of the wafer. In addition to the optical components, the asset also utilizes an automated stage, motorized wafer chuck, and motion controller. This combination of hardware ensures that the wafer is always positioned optimally for measuring, since the entire wafer remains stationary while the microscope scans across it. Furthermore, the wafer chuck is specially designed to ensure that no vibrations or misalignment occur during the scanning process. Finally, the model includes spectral imaging software, which is capable of a range of image analysis. This includes 2D image stitching, sub-pixel registration, and image-based defect classification. Such analysis allows for precision analysis down to the micron level, allowing for highly accurate analysis of wafer performance. In conclusion, KLA UV 1250 Wafer Testing and Metrology equipment is an indispensable tool for wafer testing, providing unparalleled accuracy and resolution. With its combination of lasers, optical elements, automated stage, and specialized software, the system allows for highly detailed analysis of integrated circuits on a single wafer.
