Yandong Technology 12-inch Bright-Field and Dark-Field Inspection Equipment Procurement - International Tender Announcement

This international tender announces the procurement of 12-inch bright-field and dark-field inspection equipment for Yandong Technology. The tender is based in Beijing, China, and falls under the computer, communication, and other electronic equipment manufacturing industry, with funding secured through spot exchange. Bright-field and dark-field microscopy are optical techniques used for inspecting surfaces and detecting defects. In semiconductor manufacturing, these inspection methods are vital for quality control at various stages, from wafer processing to final device inspection. Bright-field is typically used for observing surface features, while dark-field excels at detecting subtle defects, particles, or scratches that might be invisible under bright-field illumination. The 12-inch specification refers to the wafer size compatibility. Yandong Technology requires this advanced inspection equipment to ensure the high quality and reliability of its semiconductor products by identifying and characterizing microscopic defects. Bidders are expected to provide sophisticated inspection systems offering high resolution, sensitivity, and automation for efficient defect detection on 12-inch wafers.
