发明名称 Method for fabricating semiconductor devices
摘要 A semiconductor device fabrication method that improves the efficiency of semiconductor device production. A plurality of wafer substrates are set and a process for fabricating semiconductor devices each having a ferroelectric capacitor is begun. After ferroelectric layers are formed over the plurality of wafer substrates, the ferroelectric layers formed are damaged. The plurality of wafer substrates are then rearranged and treatment is performed. In each step in which the ferroelectric layers formed may be damaged, the plurality of wafer substrates are rearranged and treatment is performed. As a result, retention characteristic variations among wafer substrates in the same lot are reduced and the productivity of semiconductor devices is improved.
