  • Patent number: 4152286
    Abstract: A boron doped, silicon oxide-forming film is produced on a semiconductor wafer by coating the wafer with a solution of a silicon compound and a boron compound, in a blend of two polar organic solvents, one of which has a low boiling point, and the other has a high boiling point, between 185.degree. and 300.degree. C. During a subsequent heating step, the high boiling point solvent redissolves any crystalline precipitate that forms during spin-on, giving a more uniform film for diffusion, and consequently a damage-free wafer surface.
