Abstract :
A new spin-on-polymer with excellent physical and mechanical properties is described. AccuspinR T-24 is a siloxane based polymer which has a dielectric constant of 2.5 after cure, the lowest reported for this class of materials. In addition, thick, crack-free films can be prepared which exhibit excellent planarization and gap-fill and are suitable for both subtractive aluminum and damascene processes
