Abstract
In order to develop a method to detect low-level oxygen in thin silico n crystals by photoluminescence (PL), a radiative carbon-oxygen center (C center: 0.79 eV) is formed in silicon crystals through carbon intr oduction by ion implantation. The PL intensity of the C center of the implanted sample is significantly increased by annealing the sample at 1000 degrees C followed by electron irradiation. The possibility of d etecting a low concentration of oxygen (below 1 x 10(15) atoms/cm(3)) in a layer thinner than 1 mu m thick is seen. (C) 1995 American Instit ute of Physics.
