Publication number: 20230273516Abstract: Vacuum-integrated photoresist-less methods and apparatuses for forming metal hardmasks can provide sub-30 nm patterning resolution. A metal-containing (e.g., metal salt or organometallic compound) film that is sensitive to a patterning agent is deposited on a semiconductor substrate. The metal-containing film is then patterned directly (i.e., without the use of a photoresist) by exposure to the patterning agent in a vacuum ambient to form the metal mask. For example, the metal-containing film is photosensitive and the patterning is conducted using sub-30 nm wavelength optical lithography, such as EUV lithography.Type: ApplicationFiled: April 10, 2023Publication date: August 31, 2023Inventors: Jeffrey MARKS, George Andrew ANTONELLI, Richard A. GOTTSCHO, Dennis M. HAUSMANN, Adrien LAVOIE, Thomas Joseph KNISLEY, Sirish K. REDDY, Bhadri N. VARADARAJAN, Artur KOLICS
