Abstract: The integrated optical circuit of the present invention includes a substrate with a first cladding layer. A first core layer having one or more waveguiding elements is formed on the first cladding layer. A second cladding layer surrounds the waveguiding elements of the first core layer; the refractive index of the first and second cladding layers are selected to be less than the refractive index of the waveguiding element(s). Through simultaneous cladding material deposition and cladding material removal, the second cladding layer as deposited is substantially self-planarized, enabling further layers to be positioned on the second cladding layer without necessitating intermediate planarization. Further, the present invention permits planar waveguide cores having submicron core spacings to be covered by a subsequently-deposited cladding layer without cladding gaps, seams or other deleterious cladding defects.

In some instances, it may be easier to control the variation of one of the two processes than the other so that the more controllable process is tailored to accommodate nonuniformities introduced by the less controllable process.

Abstract: This invention is embodied in an improved process for growing high-quality silicon dioxide layers on silicon by subjecting it to a gaseous mixture of nitrous oxide (N2O) and ozone (O3). The presence of O3 in the oxidizing ambiance greatly enhances the oxidation rate compared to an ambiance in which N2O is the only oxidizing agent. In addition to enhancing the oxidation rate of silicon, it is hypothesized that the presence of O3 interferes with the growth of a thin silicon oxynitride layer near the interface of the silicon dioxide layer and the unreacted silicon surface which makes oxidation in the presence of N2O alone virtually self-limiting. The presence of O3 in the oxidizing ambiance does not impair oxide reliability, as is the case when silicon is oxidized with N2O in the presence of a strong, fluorine-containing oxidizing agent such as NF3 or SF6.
