InactiveUS20020096681A1TransistorSemiconductor/solid-state device manufacturingActive layerIon implantation
A TFT using an aluminum material for a gate electrode is manufactured at a high yield factor. The gate electrode provided over an active layer and a gate insulating film is constituted by a lamination film of a tantalum layer and an aluminum layer. In this structure, the tantalum layer functions as a stopper, so that it is possible to prevent a constituent material of the aluminum layer from intruding into the gate insulating film. An end portion of the tantalum layer is transformed into tantalum oxide, which has an effect to lower damage at ion implantation to the gate insulating film in the formation of an LDD region.
