Abstract:
1. A method of fabricating a SiCOH dielectric material comprising: placing a substrate into a plasma enhanced chemical vapor deposition reactor; providing octamethyl-1,5-disiloxane-3,7-disilacyclooctane as a cyclic carbosilane precursor, a porogen, oxygen and helium to said reactor; depositing via plasma enhanced chemical vapor deposition a dielectric film derived from said cyclic carbosilane precursor onto said substrate, said plasma enhanced chemical vapor deposition includes a reactor pressure of 5 Torr, a flow of said cyclic carbosilane precursor and said porogen from 100 to 5000 mg/m, an O treating said deposited dielectric film using a combination of thermal energy and UV light energy.
