Chemical Vapor Deposition of Hydrogen-Free Silicon-Dioxide Films

Abstract
A new source gas mixture of Si(NCO)4 and N(CH3)3 has been investigated for low-temperature chemical vapor deposition of silicon dioxide. Hydrogen-free films have been successfully deposited at 200° C for the first time. Evaluated results are also presented for deposition characteristics and deposited film properties. The breakdown-field strength and low-field resistivity were as high as 5.9 MV/cm and 6×1016 Ωcm, respectively, for the as-deposited film.
