21. Reliability and cost factors limit the number of photolithography steps that can be done. 22. The developed surface is then subjected to other processes of photolithography . . .. 23. Integrated circuits are made using photolithography , i . e . exposure to light. 24. The photolithography machines manufactured by ASML are used in the production of computer chips. 25. Creation of the master, or template, is done using traditional photolithography techniques. 26. Photolithography methods are again applied to cover all devices except the n-MOSFETs.27. Photolithography is a process in removing select portions of thin films used in microfabrication.28. It is mainly used in all photolithography processes. 29. And besides being repetitive, photolithography works only on silicon and a few other materials. 30. Other processes are called photomasks and photolithography .
