Beschreibung
Zusammenfassung:	Structures of high electron mobility thin film transistors (HEM-TFTs) are provided in this invention. In one embodiment, HEM-TFTs with a single heterojunction structure are disclosed to have a substrate, a first metal oxide channel layer, a first spacer layer, a first doped layer, a first barrier layer, a source, a drain and a gate. In another embodiment, HEM-TFTs with a double heterojunction structure are provided to have a substrate, a second barrier layer, a second doped layer, a second spacer layer, a first metal oxide channel layer, a second spacer layer, a second doped layer, a second barrier layer, a source, a drain and a gate. In yet another embodiment, HEM-TFTs with a single heterojunction structure are disclosed to comprise a substrate, a first metal oxynitride channel layer, a first spacer layer, a first doped layer, a first barrier layer, a source, a drain and a gate. In still another embodiment, HEM-TFTs with a double heterojunction structure are provided to include a substrate, a first barrier layer, a first doped layer, a first spacer layer, a first metal oxynitride channel layer, a second spacer layer, a second doped layer, a second barrier layer, a source, a drain and a gate.
