Used KLA / TENCOR 2138 #191650 for sale

KLA / TENCOR 2138 is a sophisticated mask and wafer inspection equipment designed to accurately detect debris, edge roll, and other defects on mask and wafer substrates. The system is capable of performing a wide array of automated inspection techniques and can be configured to operate at very specific resolutions and sensitivity levels. KLA 2138 is a versatile unit well-suited for a variety of applications. Users benefit from its dual-sided scanning capability, which provides access to both sides of the wafer or mask substrate with a single inspection. The machine is designed for maximum efficiency, allowing users to complete an inspection in a matter of minutes. The two main inspection components contained in TENCOR 2138 tool are its high-resolution microscope and its laser hood, which is used to create a three-dimensional map of the sample being inspected. The microscope works in tandem with the hood to detect small defects on masks and wafers that would go unnoticed by the human eye. This is achieved by scanning the material in question at sub-micron resolution. The user can elect to customize their inspections to their exact specifications in terms of resolution and sensitivity. Inspections done using 2138's microscope are incredibly accurate, and feature a defect detection rate as high as 95 percent and a false alert rate of less than 1 percent. The asset even goes beyond simply detecting the presence or absence of debris and other defects. It can also characterize the individual defects in terms of shape, size, and orientation, providing users with a thorough assessment of the inspected material. Overall, KLA / TENCOR 2138 is a highly versatile and reliable mask and wafer inspection model capable of identifying and characterizing a wide variety of small defects. With its dual-sided scanning capability, customizable inspections, and high accuracy, KLA 2138 is an indispensable tool for manufacturers looking to make sure their mask and wafer substrates are up to spec.
