Semiconductor device and method for manufacturing same
Abstract:
This semiconductor device (100) includes a substrate (10) and a TFT which is provided on the substrate. The TFT includes a gate electrode (12), an oxide semiconductor layer (14) which faces the gate electrode, source and drain electrodes (16, 18) which are connected to the oxide semiconductor layer, and an insulating layer (22) which contacts at least partially with the source and drain electrodes. The insulating layer (22) includes a lower region (22b) which contacts at least partially with the source and drain electrodes and an upper region (22a) which is located over the lower region. The lower region (22b) has a higher hydrogen content than the upper region (22a).
