Abstract
The bulk silicon quality after removal of the silicon-on-insulator (SOI) and buried oxide layer was compared with respect to the performance of avalanche photodiodes (APD) operated in Geiger-mode. The SOI technology enabled the detector and the readout circuitry to be electrically isolated. The plasma etching of the buried oxide showed lower dark counts with respect to wet etched or standard p-epi substrates.
