Latest Patents
One of Oi's latest patents is the "Nanogripper device having length measuring function and method for length measurement executed with nanogripper device having length measuring function." This invention features a fixed electrode and a movable electrode that drive each arm of the device. When a voltage is applied, a coulomb force moves the movable electrode, allowing the arms to close and grip a sample. The dimensions of the sample can be accurately measured based on the electrostatic capacity achieved between the electrodes when the sample is gripped.
Another notable patent is the "Composite system of scanning electron microscope and focused ion beam." This innovative system integrates a scanning electron microscope (SEM) with a focused ion beam (FIB) apparatus. The FIB lens barrel is designed to irradiate a focused ion beam onto a sample surface, while the SEM lens barrel observes the machining state of the sample. The FIB lens barrel includes an aperture with a preselected pattern, enabling precise machining of the sample surface during the irradiation process.
