    摘要: A method of filling a plurality of trenches etched in a substrate. In one embodiment the method includes depositing a layer of spin-on glass material over the substrate and into the plurality of trenches; exposing the layer of spin-on glass material to a solvent; curing the layer of spin-on glass material; and depositing a layer of silica glass over the cured spin-on glass layer using a chemical vapor deposition technique.

    摘要: A method of filling a plurality of trenches etched in a substrate. In one embodiment the method includes depositing a layer of spin-on glass material over the substrate and into the plurality of trenches; curing the layer of spin-on glass material by exposing the spin-on glass material to electron beam radiation at a first temperature for a first period and subsequently exposing the spin-on glass material to an electron beam at a second temperature for a second period, where the second temperature is greater than the first temperature. The method concludes by depositing a layer of silica glass over the cured spin-on glass layer using a chemical vapor deposition technique.
