Abstract
Charge pumping (CP) has been used to study defects in p-channel poly-c rystalline silicon thin film transistors (TFTs). At high frequencies ( > similar to 1 kHz), we observe anomalous CP behavior in TFTs due to ( a) the high resistivity of, and/or slow electron trapping in, the poly -Si channel and (b) the existence of a TFT drain offset region. At low frequencies, the CP technique still appears to provide a useful measu re of the TFT grain boundary defect density.
