Abstract:
1. A composition for forming a silica layer, the composition comprising: hydrogenated polysilazane, hydrogenated polysiloxazane, or a combination thereof, wherein a concentration of a sum of hydrogenated polysilazane and hydrogenated polysiloxazane having a weight average molecular weight, reduced to polystyrene, of greater than or equal to about 50,000 is about 0.1 wt % or less, based on a total amount of the hydrogenated polysilazane and hydrogenated polysiloxazane, wherein the composition has a number of in-liquid particulates, having a size of about 0.2 μm or greater, of about 100 or less per cc of solution, and wherein the hydrogenated polysilazane or the hydrogenated polysiloxazane has a weight average molecular weight of about 1,000 to about 10,000.
