8.3: Invited Paper: Advantages of IGZO Oxide Semiconductor

Oxide semiconductors as represented by InGaZnO have been developed and used for driving TFT of LCD. Since there have been discussions on comparison of oxide semiconductors with amorphous and/or poly-silicon which have been conventionally used for LCD, this paper will summarize pros and cons of each semiconductor material, deepen discussions for future developments, and clarify advantages of oxide semiconductors.
