    • A method and apparatus for identifying defective partially manufactured semiconductor wafers in a manufacturing line is described, wherein defects caused by silicon erosion created by over-etching the wafer can be detected. The method described herein is based on an in-line test of selected structures, such as FETs, located in the kerfs that surround the integrated circuit chips. Leakage current between the gate and the source-drain region is measured at FETs in each kerf. Based on the measurement, a leakage current map is created and compared to a standard map. In accordance with this comparison and to the distribution of patterns of leakage currents, it is determined whether or not the wafer is defective. This determination is performed in the kerfs after formation of the gate and source-drain regions, and prior to the wafer being completed. By detecting defective wafers at an early stage, considerable manufacturing resources are saved.
    • 描述了一种用于识别生产线中部分制造的半导体晶圆缺陷的方法和装置,其中可以检测由过度蚀刻晶片而产生的硅腐蚀引起的缺陷。 本文描述的方法基于位于围绕集成电路芯片的切口中的所选结构(例如FET)的在线测试。 在每个切口的FET处测量栅极和源极 - 漏极区域之间的漏电流。 基于测量,创建泄漏电流图并与标准图进行比较。 根据该比较以及泄漏电流图案的分布,确定晶片是否有故障。 在栅极和源极 - 漏极区域形成之后并且在晶片完成之前,在切割中执行该确定。 通过早期检测缺陷晶片,节省了相当多的制造资源。
