Abstract

We report on a new nanopore formation technique by utilizing SiC/Si(100) heteroepitaxial growth. The SiC growth onto Silicon-On-Insulator substrates was carried out by CH₃SiH₃ supersonic jet chemical vapor deposition. Inverse pyramidal pits surrounded by {111} facets were created in the top Si layer during the SiC heteroepitaxial growth. Randomly distributed nanopores with the diameter of ~10 nm were obtained in the top ~180 nm thick Si layer by removing the buried oxide layer under the pits. It was found that the oxide patterns on the top Si layer were effective for the site-control of the nanopore formation.
