ABSTRACT:
A thin film transistor having two vertically stacked channels and dual gate non-photosensitive structure, where the source drain to bottom gate structure is self-aligned. This structure occupies the same area on a substrate as a conventional single gate thin film transistor. This invention also discloses a process for manufacturing a dual gate structure with a simple three mask procedure.
