A transistor may include: a gate insulting layer, a gate electrode formed on a bottom side of the gate insulating layer, a channel layer formed on a top side of the gate insulating layer, a source electrode that contacts a first portion of the channel layer, and a drain electrode that contacts a second portion of the channel layer. The channel layer may have a double-layer structure, including an upper layer and a lower layer. The upper layer may have a carrier concentration lower than that of the lower layer. The upper layer may be doped with a carrier acceptor in order to have an electrical resistance higher than that of the lower layer. |
