    • PURPOSE: Evaluating and manufacturing methods for a silicon wafer are provided to evaluate presence and in-plane distribution of an oxygen precipitate in the silicon wafer using photoluminescence. CONSTITUTION: First in-plane distribution information about a silicon wafer(W) surface is obtained. Second in-plane distribution information about the silicon wafer is obtained. The differential information between the first in-plane information and third in-plane information, which is obtained by correcting the second in-plane information with a correction factor below 1, is obtained. Presence of an oxygen precipitate in an evaluated silicon wafer and an evaluation item which is selected from a group formed by in-plane distribution of the oxygen precipitate are evaluated based on the differential information.
    • 目的:提供硅晶片的评估和制造方法,以评估硅晶片中氧沉淀物的存在和面内分布,使用光致发光。 构成:获得关于硅晶片(W)表面的第一平面分布信息。 获得关于硅晶片的第二面内分布信息。 获得通过以小于1的校正系数校正第二平面内信息而获得的第一面内信息和第三平面内信息之间的差分信息。 基于差分信息,评价在评价硅晶片中存在氧析出物,并且根据差异信息评价选自由沉淀物的面内分布形成的组的评价项目。
