Abstract:
A method of manufacturing a semiconductor structure, the method comprising:providing a semiconductor substrate or substrate assembly; providing one or more sources of silicon in the form of a liquid or a gas;providing one or more sources of a nonsilicon-containing reaction gas in the form of a liquid or a gas;providing one or more liquid compounds of the formulas B(OR.sup.3).sub.3, P(OR.sup.4).sub.3, (O)P(OR.sup.5).sub.3, wherein each R.sup.3, R.sup.4, and R.sup.5 group is independently an alkyl or alkenyl group;vaporizing each of the compounds provided as liquids to form gases;directing the gases toward the semiconductor substrate or substrate assembly to form a condensed liquid on a surface of the substrate or substrate assembly; andthermally treating the condensed liquid to form a phosphorus- and/or boron-containing silica layer on a surface of the semiconductor substrate or substrate assembly.
