Used ZEISS A20 #9245012 for sale

ZEISS A20 photoresist equipment is a semi-automated system designed to facilitate the development of photoresists for microfabrication. It features a unique integrated design that allows for precise automated control of light exposure and features an integrated CO2 laser unit that provides high-resolution exposure of photoresist substrates. A20 photoresist machine is built from stainless steel and features an ergonomic design with an integrated touch screen, allowing for precise automated control of exposure parameters. It offers both single-step and multi-step exposure, and features dual-stage digital signal processing (DSP) that provides a highly accurate exposure level. Additionally, the tool allows for precise control of spot size, beam polarization/orientation, shutter speed and intensity. For single-step exposure, ZEISS A20 photoresist asset utilizes up to five CO2 laser sources that are controlled and adjusted through the touch screen interface. When performing a multi-step exposure, the model includes a programmable controller that is used to adjust the exposure cycle patterns. The equipment's CO2 laser provides high-resolution exposure of photoresist substrates, with a high photo rate even at lower voltages, and the ultra-thin laser providing even more accurate and directed exposures. The precision and accuracy of the photo lithography process is also improved, as the substrate is automatically aligned for each exposure, ensuring precise registration. A20 photoresist system also includes an automatic cleaning station for substrate surface treatment and a cleanroom for the photoresist coating process. The cleanroom is filled with nitrogen to ensure dimensional stability of the photoresist on the substrate. ZEISS A20 photoresist unit provides state-of-the-art microfabrication technology, making it ideal for a wide variety of application areas, including advanced optoelectronics, microfluidics, and biomedical devices.
