摘要:
Thin 200-nm-thick Si crystals were grown in Si layers amorphized with 800-keV As**2** plus ions by inducing lateral solid-phase epitaxy at 500 degree C with a 140-keV Si**2** plus pseudo-linear ion beam formed by scanning a point-focused beam at 5kHz. It is shown that reduction of dose rate of the ion beam is crucially important to induce the epitaxy because the amount of damage produced by the ions significantly increases with the dose rate and even amorphization occurs at a higher dose rate.
