Used CANON PLA 501 #293828883 for sale

CANON PLA 501 is a highly sophisticated and specialized mask aligner that can accurately and efficiently fabricate micro-scale devices with microscopic features. The aligner features an advanced alignment equipment that combines a four point centering system which employs four long-lasting alignment sensors with laser diodes for contact-free measurement of the substrate. This ensures excellent accuracy and repeatability of the substrate-to-mask registration and alignment. The aligner also boasts a precision optical unit with 10X microscope objective lens and 5X microscope eyepiece for precision control of the accommodation and applied forces. In addition, the controlling microprocessor ensures a high level of accuracy with a range of 0.1 to 2 millionth of a meter. The aligner also features an integrated mask stage for quick and easy mask positioning, enabling precise mask-to-wafer registration. The mask stage is adjustable, allowing the user to change the amount of mask overhang, which increases the depth of focus to cover a range of 0.05 to 0.7 micrometers. A variable-speed mask-plane servo drive provides precise movement and position control of the mask. The open-frame, modular design of the mask stage ensures easy accessibility, even in a congested laboratory environment. The mask is held in place using a vacuum machine, while the stage itself is stable and repeatable. Compatible masks include solution-processed organic resists, LED resists, photoresists, silicon dioxide, and metal masks. CANON PLA-501 mask aligner also features an integrated optical gauge and an automatic sharpening‰Ûª function for high accuracy and repeatability of exposure settings. The tool is designed for an ultra-high throughput of up to 10 wafers per hour, and up to 20 million alignment shots can be stored for future use. The aligner is designed for compatibility with most standard and customized photolithography benches, including those with integrated optical gauges. This makes it an ideal choice for laboratories looking to improve their productivity and accuracy in the fabrication of integrated circuits, sensors, and other micro-scale devices.
