Abstract
A method to provide low dielectric constant voids between adjacent conducting lines in a semiconductor device. Narrowly spaced metal lines are formed on the substrate surface. A dielectric layer is deposited overlying the metal lines and the substrate surface. A high water content, water saturated, environment is created for the spin-on-glass process. A pseudo-water condition exists on the surface of the dielectric layer prior to the deposition of the spin-on-glass layer. The spin-on-glass layer is deposited overlying the dielectric layer. Voids form in the spin-on-glass layer between the narrowly spaced metal lines. The spin-on-glass layer is baked. The integrated circuit device is completed.
