    摘要: A thin film sensor element includes a sensor holding substrate having an opening part and a multilayer film adhered thereon at least consisting of an electrode film A, an electrode film B having (100) plane orientation, and a piezoelectic dielectric oxide film present between the electrode film A and the electrode film B. As a result, a thin film sensor element which is small, light, highly accurate, and inexpensive can be attained which can be used for an acceleration sensor element and a pyroelectric infrared sensor element.
    On the surface of a flat plate KBr substrate 1, a rock-salt crystal structure oxide of a conductive NiO 12 is formed by a plasma MOCVD method whose vertical direction is crystal-oriented to (100) direction against the substrate surface. By means of a sputtering method, a PZT film 4 is formed by an epitaxial growth on that surface, and a Ni-Cr electrode film 15 is formed thereon. Next, the multilayer film structure is reversed and adhered to a sensor substrate 7 having an opening part with an adhesive 20. After a connection electrode 19 is connected, the whole structure is washed with water, thereby removing the KBr substrate 1.

    摘要: For applying ferroelectrics to electronic devices, the poling treatment of the ferroelectrics has been necessary in order to uniform directions of spontaneous polarizations, Ps, in each ferroelectric. This treatment brings about (1) low yields of the devices, (2) difficulties in the fabrication of array devices, and (3) difficulties in the formation of ferroelectric films on semiconductor devices.
    Now it has been found that a self-polarized film in which spontaneous polarizations, Ps, are unidirectional can be formed by sputtering a ferroelectric materials containing lead under such conditions that the orientation of Ps will be controlled without poling treatment and a high-performance ferroelectric device can be obtained in a high yield by using this film, and thus a porcess for producing such devices has been found.

    摘要: In a pyroelectric infrared detector, there is provided a slit which interrupts an infrared image which is incident to a pyroelectric element array, and respec­tive pyroelectric elements forming one row of the pyroelectric element array are wired so that they are connected in series electrically and adjacent pyroelectric elements generate counter-electromotive forces. An infrared image irradiated on respective pyroelectric elements is scanned successively by the movement of the slit in a row direction on the pyroelectric element array, thus obtaining an infrared image which is being irradiated onto respective pyroelectric elements from time series signals produced at both ends of the pyroelectric element array.
