Used BIO-RAD Quaestor Q7 #9312796 for sale

BIO-RAD Quaestor Q7 is a mask and wafer inspection equipment designed to provide accurate and detailed measurements of the size and shape of mask and wafer features. The system features a large field of view, allowing it to view multiple large scale features on the same wafer simultaneously, or image a single large device with two simultaneous views. The unit is capable of acquiring accurate spatial and dimensional information quickly, with a measurement speed of up to 10 features per second. The machine uses advanced optics and lighting, including a proprietary, multi-angle beam design, providing high-resolution imaging capability in a variety of sample configurations. It also includes advanced, automated systems to control contrast and size relationships of mask or wafer features, as well as the ability to judge alignment and other size-based characteristics with detail. The tool's powerful image processing software allows for identification of defects or areas of interest quickly and efficiently. It can detect a variety of different defects, including but not limited to, chipped and cracked features, pinholes, microbridges, surface and interface defects, and particles. The asset can also verify the correctness of gray-level during inspection. Data from the model's measurement and inspection process can then be exported to a variety of file formats, including both PDL1 (PDF/EPSF) and CAD formats, for further analysis. A 3D reconstruction feature is also provided to obtain an accurate and detailed 3D image of the mask or chip for further inspection and analysis. The equipment includes options to connect to other infrastructure, such as a built-in Ethernet connection and optional communications link with third-party metrology instruments, networks, databases and SPC/SQC systems. Additionally, it provides dedicated programming tools and a graphical user interface (GUI) to program and review image logs. Finally, accessories such as a microscope and sample chamber are also available for additional features and precision. Overall, the BIORAD BIO-RAD QUAESTOR Q 7 provides accurate, detailed measurements and defect inspection of very small features, making it a valuable tool for microelectronics and semiconductor manufacturers who require precise and fast measurements for their mask and wafer inspection tasks.
