Used CANON MPA 500FA #293819197 for sale

CANON MPA 500FA is a fully automated mask aligner that performs accurate and precise wafer alignment. It is designed to meet the demands of photolithography processes in semiconductor device production. This aligner is equipped with the latest high-precision optical system and provides high accuracy, excellent throughput, and reliable alignment. CANON MPA-500FA features a large, independent, flat field of view (FOV) that enhances alignment accuracy and throughput. The reticle and wafer stages provide excellent repeatability, providing exceptionally low wafer-to-wafer variations and enabling reliable operation for high-precision device fabrication. It is optimized for a range of substrates, including bonded wafers, and is a particularly suitable tool for services involving multiple pattern overlays and high resolution applications. This mask aligner uses a three-step alignment procedure for mask registration. The system measures numerical target patterns on the mask and wafer, and then performs a multi-frame image acquisition process to superimpose the patterns. Finally, a global search algorithm is used to maximize pattern correlations to achieve accurate registration. As a result, alignment accuracy is improved and a high throughput rate is achieved. In addition, MPA 500 FA also offers a full suite of tools for efficient operation, such as edge recognition, wafer and mask referencing, and automated focus adjustment. These features help simplify the process of setting up the machine and ensure that it works reliably to achieve the desired alignment. The automated focus adjustment enables quick and easy adjustments to account for changing substrate patterns or environmental conditions. Overall, CANON MPA 500 FA is an excellent automated mask aligner that is highly accurate and provides high throughput. The advanced optical system, multi-frame image acquisition process, and several other features allow it to achieve a high degree of accuracy and reliability. This versatile tool is suitable for a variety of photolithography processes in semiconductor production.
