Description
Claims (4)
- 特定の添加元素を不純物として含むスクラップシリコンを選別する方法であって、各スクラップシリコンの抵抗率を測定し、この測定された抵抗率に基づいて前記特定の添加元素を含むスクラップシリコンの一次選別を行い、その後に、各スクラップシリコンをエネルギー分散型蛍光X線分析装置(EDX)による非破壊分析にかけ、得られたスペクトルデータから前記特定の添加元素を含んでいるか否かを判定し、この判定結果に基づいて前記特定の添加元素を含むスクラップシリコンを選別することを特徴とする方法。
- 請求項1に記載のスクラップシリコンの選別方法であって、各スクラップシリコンはn型であり、前記特定の添加元素はアンチモン又はヒ素であることを特徴とする方法。
- 請求項1に記載のスクラップシリコンの選別方法であって、特定の添加元素の含有量がエネルギー分散型蛍光X線分析装置(EDX)の検出可能レベルよりも少ないために検出されない場合でも、その他の添加元素が検出されない場合には、前記特定の添加元素を含 んでいると判定することを特徴とする方法。
- 請求項3に記載のスクラップシリコンの選別方法であって、各スクラップシリコンはn型であり、前記特定の添加元素はリンであることを特徴とする方法。
