TERPOLYMERS CONTAINING SULFUR DIOXIDE FOR ELECTRON BEAM POSITIVE RESISTS

TERPOLYMERS FOR ELECTRON BEAM POSITIVE RESISTS Electron beam positive resists are formed from terpolymers of (a) an alpha olefin, (b) sulfur dioxide, and (c) a compound selected from the group consisting of cyclopentene, bicycloheptene and methyl methacrylate. The terpolymers have the particular une...

Zusammenfassung:	TERPOLYMERS FOR ELECTRON BEAM POSITIVE RESISTS Electron beam positive resists are formed from terpolymers of (a) an alpha olefin, (b) sulfur dioxide, and (c) a compound selected from the group consisting of cyclopentene, bicycloheptene and methyl methacrylate. The terpolymers have the particular unexpected advantage of being resistant to cracking of the films.
