Abstract:
1. An electronic device, which comprises a radio-frequency IC tag having a nonvolatile memory comprising a semiconductor device, wherein the semiconductor device comprises: a thin film transistor by forming a polysilicon thin film on an insulating substrate, the thin film transistor comprising a gate electrode via a gate insulating film, and source/drain regions and a channel region by ion implantation in the polysilicon thin film by using the gate electrode as a mask; an interconnection layer formed on an interlayer dielectric film covering this thin film transistor and a first contact to be connected to the thin film transistor through the interlayer dielectric film; a silicon hydronitride film formed on the interlayer dielectric film so as to cover the interconnection layer; a lower electrode formed on this silicon hydronitride film and a second contacted to be connected to the interconnection layer through the silicon hydronitride film; a ferroelectric layer formed on the lower electrode; and an upper electrode formed on the ferroelectric layer, wherein a hydrogen concentration of the thin film transistor is higher than a hydrogen concentration of the ferroelectric layer, and wherein the semiconductor device further comprises a protective oxide film between at least one of the source region, the drain region, the interlayer dielectric film, and the channel region, and the insulating substrate, wherein the channel region comprises a plurality of Si—H bonds; and further having a transmission data encoder element, a received data decoder element, an antenna element for data exchange with the exterior, and a control element for controlling these elements.
