Abstract:
1. A transistor, comprising: a channel layer on a substrate, the channel layer including a zinc (Zn)-containing oxide; a source and a drain, respectively, contacting opposing ends of the channel layer; a gate corresponding to the channel layer; and a gate insulating layer over the channel layer, the channel layer having a first surface adjacent to the substrate, a second surface facing the first surface, and a channel layer-protection portion on the second surface, the channel layer-protection portion including a fluoride material, the channel layer-protection portion including a first region, the channel layer-protection portion including a fluoride material-containing layer having the fluoride material, and the fluoride material-containing layer including at least one selected from the group consisting of polyfluorovinylidene, fluoroolefin, polytetrafluoroethylene, polyhexafluoroethylene, fluoroethylenepropylene, perfluoropolyether, perfluorophenylene, perfluorobiphenylene, perfluoronaphthalene, polyvinylfluorocinnamate and combinations thereof.
