Abstract(in English) | The dependence of poly-Si TFT characteristics on the density of oxide interface traps (Dit) and grain boundary traps (Dgb) has been analyzed. First, actual trap densities are extracted using a low-frequency C-V characteristic, I-V characteristic and extraction technique that has been developed by the authors. Next, the dependence of TFT characteristics is analyzed using device simulation by varying these trap densities from actual ones. It is found that the subthreshold swing and threshold voltage mainly depend on Dit, while the transistor mobility depends on Dgb. By applying these results to diagnosis of fabrication processes, it is found that oxygen plasma treatment reduces Dit, while PECVD-TEOS for gate-oxide generates Dgb. |
