发明名称 PROCESS FOR PREPARING A STABILIZED IDEAL OXYGEN PRECIPITATING SILICON WAFER
摘要 <p>The present invention is directed to a single crystal Czochralski-type silicon wafer, and a process for the preparation thereof, which has a non-uniform distribution of stabilized oxygen precipitate nucleation centers therein. Specifically, the peak concentration is located in the wafer bulk and a precipitate-free zone extends inward from a surface.</p>
