The conduction mechanisms of the off-current in low temperature (.leq. >$600^{\circ}C$) processed polycrystalline silicon thin film transistors (LTP poly-Si TFT'S) have been systematically studied. Especially, the temperature and bias dependence of the off-current between hydrogenated and nonhydrogenated poly-Si TFT's were investigated and compared. The off-current of nonhydrogenated poly-Si TF's is because of a resistive current at low gate and drain voltage, thermally activated current at high gate and low drain voltage, and Poole-Frenkel emission current in the depletion region near the drain at high gate and drain voltage. After hydrogenation it has shown that the off -current mechanism is caused mainly by thermal activation and that the field-induced current component is suppressed.

Inflammatory fibroid polyps(IFP) is a relatively rare, benign polyp which is composed of fi- brous connective tissue, blood vessels, and infiltration of eosinophils. The majority of inflam- matory fibroid polyps has been reported with pathologic specimen in stomach and small intes tine. Terminal ileal inflammatory fibroid polyps differ from gastric lesion because they are larger and are almost all pedunculated. As a result, they tend to produce intussusception with intestinal obstruction. We present a case of inflamrnatory fibroid polyp of distal ileum causing intussusception with literature review.(Korean J Gastroenterol 1994; 26: 874 878)
