    摘要: A ferroelectric memory device has a high performance, includes no Pb, and can be directly mounted onto an Si substrate. The ferroelectric memory device includes a (001)-oriented BiFeO3 ferroelectric layer 5 with a tetragonal structure, which is formed on an electrode 4 made of a perovskite material formed on an Si oxide film. The electrode 4 with a perovskite structure is formed by an ion beam assist method.

    摘要: A liquid ejecting head includes a flow channel forming substrate having a pressure generation chamber communicating with a nozzle opening and arranged in parallel along a lateral direction. A piezoelectric element is provided on one surface of the flow channel forming substrate in correspondence to the pressure generation chamber, and has a first electrode, a piezoelectric layer provided on the first electrode and a second electrode provided on the piezoelectric layer. In a direction intersecting with the arrangement direction of the pressure generation chamber, in boundaries between an active section that is a substantial driving section and an inactive section that is not a substantial driving section of the piezoelectric layer of the first electrode, an opening group is provided including at least one opening in the active section and the inactive section.
