Used UNKNOWN (Mask Aligners) for sale

Mask aligners are essential tools used in lithography processes for small-scale manufacturing in various industries. Although the manufacturer of the mask aligners mentioned is unknown, the description generally applies to most mask aligners. Mask aligners are used to transfer a pattern from a mask onto a substrate, enabling precise alignment and positioning. They consist of a UV light source, a mask holder, and a substrate holder. The substrate and mask are aligned using precise microscopes, ensuring accurate pattern transfer. The advantages of mask aligners include high resolution, excellent alignment accuracy, and ease of use. They offer good process control, making them suitable for applications such as microelectronics, MEMS devices, and photonics. They are also versatile, allowing various types of substrates to be aligned. Examples of mask aligners include the MA 04, which is a popular model often used for research and development purposes. It offers features such as multiple wavelengths of UV light, automatic alignment, and computerized control. Another example is the SUSS MA 6, which is widely used in the semiconductor industry for photolithography processes. Overall, mask aligners from different manufacturers provide similar functionalities, helping achieve high precision and reliability in pattern transfer processes.
