We describe vitreous silica as a two-phase system. Low-temperature phase A and high-temperature phase B are connected by a solid-state phase transition and the phase transition temperature should be higher than the glass transition temperature. This

The elements near the pupil of a diffraction-limited optical system are examined for the effects of radiation-induced compaction on optical performance. The Zernike phase aberration terms resulting from 193-nm-induced compaction in these element are

A number of fused silica samples were evaluated for their resistance to densification by deep UV radiation at 193 nm wavelength. Density changes for all the samples equal the product of a material dependent constant and the absorbed two-photon dose t

Lens technology has advanced to the point where lithographic feature sizes equal to, or even smaller than, the wavelength of the light used in the stepper can be achieved in production. How far optical lithography can go from here depends both on how

The transport of copper in silicon dioxide thermally grown on single crystalline silicon was studied by capacitance techniques, secondary ion mass spectroscopy (SIMS) analysis, and Rutherford backscattering spectrometry (RBS). Metal/oxide/silicon (MO

The quality of epitaxial silicon grown on regions exposed to plasma etching using He, CHF3, and CF4 etching gases has been studied. Plasma‐etch‐induced surface damage leads to defects in the epilayers. Dislocation loops and precipitates at the ep

A tubular hot-wall silicon epitaxial reactor operating at reduced pressure is described. It has been constructed by modifying a commercial low-pressure chemical vapor deposition furnace and is proposed as a potentially cost-effective means of deposit

A tubular hot-wall silicon epitaxial reactor operated in the selective deposition regime is characterized for growth rate uniformity in both the radial and longitudinal directions. The range of experimental conditions includes temperatures from 900 d

The low‐temperature epitaxial growth of Si under conditions in which no nucleation occurs on SiO2 (selective growth) results in interesting new surface morphology. For substrates free of nonvolatile surface contaminants, specular defect‐free film
