• 論文の詳細を見る

• We have investigated the etching properties of MFIS structure to fabricate Pt/SBT/NO/Si structure for the transistor gate in MFIS-FET. Etch rates of blanket platinum and SBT films and characterization of etched platinum structures using a patterned PECVD-SiO_2 mask on blanket platinum films were observed. Finally, we observed that etch rates of Pt and SBT and the etch profile were varied with various etch parameters. It was also investigated that the etching damage in SBT films during RIE process influenced on the electrical propelled of ferroelectric materials.
