Abstract :
Proton irradiation was conducted on Czochralski (Cz) and floating zone (Fz) boron-doped p-type Si wafers at room temperature with the doses ranging from 1×1013 cm-2 to 2×10 15 cm-2. A p-n junction formed in the Cz wafers when the dose reached a value between 1.0×1013 cm-2 and 3×1013 cm-2 while a p-n-p structure formed in the Fz wafers. The formation of p-n and p-n-p structure was confirmed by the combined use of Hall measurements, current-voltage (I-V) measurements, spreading resistance (SR) measurements, and cross-sectional electron beam-induced current (EBIC) measurements
