In the silicon wafer, when the wafer is exposed to an ion of a heavy metal such as copper or nickel in a device manufacturing process, the copper and nickel can be captured by the action of intrinsic gettering (IG) in the course of a heat treatment, and, when a polysilicon layer is formed as a strain layer, iron and copper can be captured by the action of an extrinsic gettering (EG) using the polysilicon as a strong point for the capture.

Abstract: A plurality of minute ID marks are inscribed on a semiconductor wafer which is under manufacture, without imposing adverse effect to the wafer, in order to make the marks less susceptible to surface treatment to be performed during the course of manufacture. Further, the minute ID marks act as mutual backups. Inscribing such minute ID marks on a semiconductor wafer prevents confusion due to effacement of ultra-minute marks and eliminates worry about the impossibility of tracing a semiconductor wafer.
