AbstractDeep level transient spectroscopy (DLTS) in conjunction with other analytical techniques was used to establish a correlation between the leakage current in the TiSi2/p+/n-Si shallow diodes (0.25 micron) and the Ti-related Ec - 0.23 eV deep trap. It was found that Ti diffused into the junction region durin the TiSi2 formation and caused leakage currents with values up to 2 × 10−8 A/cm2. Further increases of the leakage current were related to the formation of a TiSi2/n-Si Schottky barrier.

The effect of the Schottky barrier height on the detection of the midgap defects EH6 and EH7 in 4H-SiC by deep level transient spectroscopy (DLTS) is systematically studied. The results show that the DLTS peak height - and as a consequence the observed defect concentration - increases with the increasing barrier height and saturates above 1.5 eV for EH6 and above 1.7 eV for EH7, while below 1.1 eV the DLTS peak height completely disappears. A model is applied, which determines the position of the quasi-Fermi level in the space charge region as a function of the barrier height and of the reverse bias applied and which explains the variation of the DLTS peak height.
