Abstract

EBIC contrast of structural defects in as-received and hydrogen passivated polysilicon ribbon is studied using aluminum Schottky barrier diodes. Enhanced charge collection after passivation is demonstrated by comparing the EBIC signal from two sections of a split ribbon, one half of which was passivated. Electrical activity of specific linear defects before and after passivation is examined by recording charge collection profiles across these defects under standardized conditions of beam voltage and current. Such measurements show that passivation does reduce the electrical activity of selected defects. Possible reasons for this behavior will be discussed.
