Heidelberg uPG 501

An optolithography technique in which a laser beam/ LED is used to form the desired patterns on the photoresist is called laser /LED writing (Direct writing). 

The specialty of the Mask Writer is that it can be used for direct pattern generation on any substrate using photolithographic principles with or without using a conventional mask plate. The main purpose of the Mask writer is to make photolithographic mask reticles and masks up to 5inch in Heidelberg µPG 501 system.
