Hello List.
I found some video clips from a Dutch (ex Philips) Engineer who builds his own DIY maskless stepper :-)
Part 1: Optisc https://www.youtube.com/watch?v=_w0Z2Y5vaAQ Part 2: Mechanics https://www.youtube.com/watch?v=MdRwiI6VLmk Part 3: Electronics and Software https://www.youtube.com/watch?v=ebv_9cmLNqo
Part ?: Building a Small Cleanroom for Photolithography https://www.youtube.com/watch?v=bkmVmsMUsJU
I think all videos here are a great source of inspiration.
Regards, Hagen.
