Used KLA / ICOS CI 9450 #9208707 for sale

KLA / ICOS CI 9450 is an inline mask and wafer inspection system used to monitor the quality of the fabrication process. This system provides an automated, thorough inspection of each phase of the manufacturing process, from the mask to the wafer. KLA CI 9450 consists of four phases: mask inspection, process inspection, die inspection, and wafer inspection. The Mask Inspection phase uses an edge detection algorithm to evaluate the accuracy of the geometry of the mask's features, such as line widths, shape, and contrast. This algorithm also ensures proper alignment and placement of all of the mask's components. The Process Inspection phase evaluates the quality of the lithography process that generates the mask, such as exposure level, depth, and linearity of the pattern. This phase also checks for deviations from the desired feature geometry. The Die Inspection phase checks for the presence and accuracy of the transistors, interconnects, and other components that are used to create the chip design. This phase also monitors the wafer's surface quality, which can affect the reliability of the chip product. Finally, the Wafer Inspection phase looks for defects and contaminants on the wafer surface after the devices have been formed. This allows any defective dies to be identified and removed before they can be included in the final product. ICOS CI-9450 is a highly reliable and accurate mask and wafer inspection system. With its automated four-stage scanning process, it is able to detect defects and contamination in every phase of the fabrication process, helping to ensure the highest quality of the end-product. It operates quickly and efficiently, minimizing the time and money required to perform necessary quality checks.
