MF153500 - SEMI MF1535 - Test Method for Carrier Recombination Lifetime in Electronic-Grade Silicon Wafers by Noncontact Measurement of Photoconductivity Decay by Microwave Reflectance StdTpc-Wafer Edge Profile This Test Method covers techniquesIf the free carrier density of an electronic grade semiconductor is not too high, the carrier recombination lifetime is controlled by impurity centers that have energies located in the forbidden energy gap. Many metallic impurities form such recombination centers in silicon. In most cases, very small densities of these impurities (1010 atoms cm3) reduce the carrier recombination lifetime and adversely affect device and circuit performance. Such
