Ionplated oxide coatings for protection against corrosionAbstract: Effects of the bias voltage on the properties and structure of sputtered and ion-plated coatings

This letter presents structural properties of silicon epitaxy grown at 300 °C by plasma enhanced chemical vapor deposition from SiH4/H2. The ratio of H2 to SiH4 flow rate and rf power of plasma was found to play an important role for epitaxial growth. The base pressure of the chamber was greater than 3×10−6 Torr. The substrates were ex situ cleaned by the spin-etch method prior to wafer loading. A H2 baking step was carried out prior to epitaxial deposition. Cross-section transmission electron microscopy and secondary ion mass spectroscopy were used to inspect the quality of Si films. The thickness of the silicon epitaxy is about 0.3 μm, which is grown at a rate of 5.6 nm/min.
