Used NANOMETRICS / BIO-RAD / ACCENT Quaestor Q7 #9112912 for sale

NANOMETRICS / BIO-RAD / ACCENT Quaestor Q7 is a leading edge mask & wafer inspection equipment designed for cost-effective process control, yield management, and defect detection in semiconductor mask and wafer manufacturing. The system utilizes advanced optical techniques to detect and analyze defects on the surface of masks and wafers, allowing process engineers to quickly identify and correct issues that could impede production and yield. The Q7 unit utilizes a monolithic optical machine consisting of four distinct subsystems: illumination, imaging, optics, and detection. This tool is designed to achieve optical resolution beyond the Exabits, providing a distinct advantage over traditional imaging systems. The fiber-optic-based illumination asset allows for light uniformity across the full scan of the mask or wafer. The imaging subsystem provides high-definition imaging capabilities without the blur or distortion of traditional optical systems, accurately capturing even the smallest of defects. The Q7 optics model operates in a linear, or diverging geometry, providing higher accuracy and a larger field of view for precise defect detection and measurement. Lastly, the detection subsystem utilizes an Architecture Mark-to-scape detection algorithm to quickly detect anomalies and defects on the surface. The Q7's features go beyond simply detecting defects. To facilitate easier testing and data analysis, the equipment comes with a user-friendly Graphical User Interface (GUI) which allows users to control and configure the system's settings, and provides a comprehensive suite of measurement and analysis tools that can be used to detect minute imperfections and trend analysis. The Q7 also comes equipped with an automated measurement unit (AMS), providing process engineers with the ability to collect large sets of data with high accuracy. This data can be used to assess the effectiveness of fabrication processes, track wafers and identify trends in production data. This data can be uploaded via USB or Ethernet, allowing for large amounts of data to be stored and analyzed easily. The Q7 is Low Maintenance and highly adept in providing large amounts of data in a small footprint. Its advanced optical capabilities are suitable for both mature solutions and development processes for the production of sub-4nm nodes, ensuring minimal downtime and increased yields.
