Filed: 1994-03-11
Abstract: PURPOSE:To simplify measurement and improve precision by a method wherein a diffusion length of a minority carriers in a state of activating a p type silicon wafer is measured by a SPV method and a diffusion length in a re-coupling state after re-coupling is measured, and iron concentration of defect layers with high density is obtained from a difference in a value based on a measure value, etc. CONSTITUTION:A silicon wafer (S21) is a p type that boron is made dopant and a defect layer is formed inside a thickness direction and a non-defect layer is formed on both end surface. A part having density different in the defect layer is removed by chemical etching (S22). Next, iron-boron in a region being a measurement object of the defect layer is separated by an optical excitation of a light-emitting, a heating furnace or the like and Fe-B is activated in a state of Feint+B and promptly cooled (S23). From the surface of the defect layer in a separation state being Feint+B by a SPV method, a diffusion length La of a minority carries is measured (S24). Successively, until the separated Feint+B is re-coupled to Fe-B (S25), it is left freely to measure a diffusion length Lb1 (S26) to obtain a difference.
