Used NANOMETRICS / BIO-RAD / ACCENT Q200i #9235491 for sale

NANOMETRICS / BIO-RAD / ACCENT Q200i is a high performance mask and wafer inspection equipment peripheral. It is specifically designed to improve the manufacturing process of advanced semiconductor production and provides superior image quality and alignment accuracy for precision mask and wafer scanning. The system includes a highly reliable, crystalline sample stage for precise, repeatable positioning and alignment of mask and wafer samples, as well as an integrated image tactile defect detection mechanism. ACCENT Q200i utilizes ACCENT-level optics and optics-level imaging technology to image and reveal difficult-to-detect defects on today's ultra-thin semiconductor structures. Its effective field of view is enlarged to the point of encompass the entire mask area, providing detailed, magnified views of areas as small as 1 μm. The unit produces high-quality defect images with greater resolution than can be achieved with traditional optical methods, enabling it to pinpoint even the slightest protective layer depositionm defects. BIO-RAD Q200i's advanced computing capabilities allow for sub-nanosecond imaging and ultra-precise image analysis. The machine can compare multiple images in order to detect slipping of alignment during the scan and stop the scan before any damage may occur. This feature helps to ensure the maximum quality of the final products. Q200i provides exceptional clarity, repeatability and reliability in mask and wafer imaging. It can be integrated with existing automated equipment for improved efficiency, and its advanced optics and imaging capabilities provide an excellent advantage for production of the highest quality wafers and devices.
