Used LASERTEC M8351 #9386141 for sale

LASERTEC M8351 Mask & Wafer Inspection Equipment is an automated inspection system that utilizes laser optics to accurately and reliably inspect wafers as thin as 0.13mm and masks up to 8"x10" or larger. It features a HD digital microscope that provides high magnification imaging with a depth of focus enabling visual verification of inline features as small as 1 micron. The unit is capable of full-field or line of sight inspections to inspect for scratches, contamination, edge defects and other critical feature defects. It can also detect contamination on the edge of the wafer or mask that could cause higher sheet resistance readings leading to inferior device performance. The machine is based on a Helium-Neon laser light source that delivers a bright light onto a wafer or mask. This highly controllable laser beam then sweeps across the surface of the wafer and mask in a linear fashion. The reflected light is then synchronized with the signal from an analog-to-digital converter (ADC). The ADC then sends the information to the laser optics processor which then uses an algorithm to analyze the image and to detect defects. This tool is able to detect any kind of defect or contamination within seconds and is a versatile and reliable tool for ensuring the highest quality standards in product manufacturing. It performs both two-dimensional and three-dimensional scans of the wafers and masks and any defect found is visible on screen enabling quick and simple defect classification. The asset can store up to 2,000 images making it ideal for long-term process control and minimization of human errors. The overall design makes LASERTEC M 8351 a robust and easy to use model, capable of withstanding harsh factory environments and reducing manual labor costs. The equipment also has advanced automation capabilities allowing it to perform single or multiple-pass inspections with different parameters for each lot size. Its modular design allows users to select the most suitable configuration of optics, sensors and illumination sources for all applications. The powerful combination of speed, accuracy, and reliability makes M8351 Mask & Wafer Inspection System an excellent choice for various industry applications. It ensures consistency in product quality and can help reduce potential negative impacts on customer satisfaction.
