M. Saito et al., OXYGEN CONCENTRATION IN THE TOP SILICON LAYER OF SILICON-ON-INSULATORMATERIALS FORMED BY LOW-DOSE IMPLANTATION OF OXYGEN, JPN J A P 2, 35(3B), 1996, pp. 359-361
Oxygen concentration in the top silicon layer of silicon-on-insulator
materials formed by low-dose implantation of oxygen has been measured
by means of secondary ion mass spectroscopy. A value of less than 1 x
10(17) atoms/cm(3) has been obtained. We propose that the oxygen conce
ntration in the top silicon layer is controlled by oxygen out-diffusio
n during the wafer cooling process.
