| Summary: |
The effects of atmospheric pressure chemical vapor deposition (APCVD) gettering on material quality of industry standard mc-Si wafers has been studied on a microscopic level and compared to POCl3 gettered samples. The interaction of the gettering efficacy with the microscopic defect structure has been studied by a combination of measurements of the effective minority charge carrier lifetime (eff), interstitial iron (Fei), optical microscope images of defect structures revealed with Secco etching, a subsequent high resolution etch pit density (EPD) analysis as well as Electron Beam Induced Current (EBIC) and Electron Backscatter Diffraction (EBSD). Findings include a similar gettering quality of APCVD- and POCl3-based glasses and a reduction of EPD after the gettering step.
