Abstract
An embedded LSI includes a FeRAM macro block and an associated logic circuit section. A hydrogen barrier layer covers the FeRAM macro block as a whole and exposes the logic circuit section. The edge of the hydrogen barrier layer overlies the peripheral circuit of the FeRAM macro block and the boundary separating the FeRAM macro block from the logic circuit section. The ferroelectric capacitor is protected by the hydrogen barrier layer against hydrogen during a hydrogen-annealing process.
