  • Publication number: 20240008737
    Abstract: An ophthalmologic imaging method is implemented by an control unit of an ophthalmologic imaging device for acquiring entire image data of the tissue by repeatedly performing the steps of: setting a scanning position; acquiring the partial image data by applying, to an optical scanning unit, a driving signal that causes the optical scanning unit to scan light on a tissue of a subject eye at the scanning position that was set this time; and continuously operating the optical scanning unit after capturing the partial image data based on the scanning position that was set this time was completed by applying, to the optical scanning unit, a continuous driving signal.

  • Patent number: 10438861
    Abstract: To predict a temperature rise amount due to self-heating of a resistance value of a gate electrode with high accuracy in an HCI accelerated stress test. A gate electrode for gate resistance measurement (for temperature monitoring) that has contacts on its both sides, respectively, is disposed adjacent to the gate electrode. At the time of gate ON of the gate electrode, voltages that are substantially the same voltages as that of the gate electrode and have a minute potential difference between its contacts are applied between the contacts of the gate electrode for gate resistance measurement (for temperature monitoring), and a resistance value of the gate electrode for gate resistance measurement (for temperature monitoring) is measured.

  • Publication number: 20170309728
    Abstract: In a process of implanting ions of an n-type impurity for threshold control into a semiconductor substrate surrounded by an element isolation portion, a resist pattern is formed such that the resist pattern covers a divot formed at a boundary portion of the element isolation portion with an SOI layer. Thus, since ions of the n-type impurity are not implanted into the divot, an etching rate of the divot in a cleaning process or the like is not accelerated, and etching can be suppressed. As a result, a BOX layer is prevented from becoming thin, so that degradation of a TDDB characteristic of the BOX layer can be prevented.
