    摘要: Transistors are formed by depositing at least one layer of semiconductor material on a substrate comprising a polyphenylene polyimide. The substrate permits the use of processing temperatures in excess of 300° C. during the processes used to form the transistors, thus allowing the formation of high quality silicon semiconductor layers. The substrate also has a low coefficient of thermal expansion, which closely matches that of silicon, thus reducing any tendency for a silicon layer to crack or delaminate.

    摘要: A thin-film transistor array comprises at least first and second transistors. Each transistor comprises a source electrode, a drain electrode a semiconductor electrode, a gate electrode, and a semiconductor layer. The semiconductor layer is continuous between the first and second transistors. The semiconductor layer is preferably unpatterned. In various display applications, the geometry of the transistors is selected to provide acceptable leakage currents. In a preferred embodiment, the transistor array is employed in an encapsulated electrophoretic display.
