Abstract:
An active matrix device comprising:a substrate;a thin film transistor formed over said substrate, said thin film transistor comprising a crystalline semiconductor film including at least source, drain and channel regions;a first electrode formed over said substrate;a first interlayer insulating film formed over said first electrode, said first interlayer insulating film covering said thin film transistor;a second interlayer insulating film comprising a different material from said first interlayer insulating film formed on said first interlayer insulating film;an opening selectively formed in said second interlayer insulating film to expose a surface of said first interlayer insulating film therein;a second electrode formed on said first interlayer insulating film in said opening anda capacitor formed between said first and second electrodes in said opening with at least said first interlayer insulating film interposed therebetween.
