Abstract
Porous silica spin-on dielectrics (SOD) films with low dielectric constant (k ∼ 2.0), high Young's modulus (E ∼ 7.5 GPa), and small pores (∼ 0.2 nm) were obtained only with ultraviolet (UV) curing within 1min at 350 °C but without hydrophobic treatment process. Optimized UV curing condition and composition of precursor solution can give the low-k film applicable to 32 nm-node interconnect technology and beyond.
