Abstract
The present invention provides a doped homojunction chalcogenide thin film transistor and a method of fabricating the same, comprising forming an N-type chalcogenide layer constituting a channel layer on a substrate, forming and patterning a diffusion prevention layer on the upper part of the N-type chalcogenide layer, and forming a P-type chalcogenide layer constituting source and drain regions by depositing and diffusing Te alloy on the N-type chalcogenide layer. With the present invention, a thin film transistor can be fabricated using chalcogenide material having N-type conductivity and chalcogenide material having P-type conductivity.
