Used KLA / TENCOR Archer #9386838 for sale

KLA / TENCOR Archer is a mask and wafer inspection equipment used in semiconductor manufacturing to detect defects on the surface of wafers. The system is made up of an image sensor, a light source, optical components, and sophisticated software algorithms. It scans each wafer using multi wavelength illumination and phase-shifting to identify patterns of light and dark areas that indicate surface defects. The image sensor in the unit is capable of capturing patterns of high-resolution images from different angles and at different depths. This is possible by using brightfield, darkfield, oblique, and polarised illumination. The data collected is then processed by the machine's powerful software algorithms and combined to create a detailed 3D surface image. The light source in the tool is a highly adjustable and optimisable source of ultraviolet and infrared light. This asset also uses features such as die-to-die overlay and focus variation mode. Die-to-die overlay allows the model to compare different scans and focus variation mode provides more accurate and detailed measurements. The optical components of the equipment, such as lenses, mirrors, and filters, are used to enhance the quality of the captured images. The lenses help to accurately capture detailed images by refracting light in different directions while the filters are used to eliminate unwanted noise from the images. The mirrors also help to tilt the image sensor and provide a different image angle. KLA Archer is an advanced mask and wafer inspection system that is capable of detecting defects as small as 5nm in size. This unit uses the latest technologies and sophisticated algorithms to capture highly accurate and detailed images of the wafers. It has been designed to improve production efficiency, reduce rework and replacement costs and ensure the highest quality products.
