Application: Scanning probe microscope, sample observation processing system, and electric characteristic evaluation device (Patent ID: US20240168052A1)
The patent filed by Hitachi Ltd. describes a scanning probe microscope that enhances visibility of a marker in broad and high-speed observation using a magnifying observation processing device. The marker is strategically placed to match the aspect ratio of the observation visual field with the observation angle around the region of interest. The marker, typically formed by scratch scars of multiple lines, aims to improve edge contrast for better observation results.
The scanning probe microscope includes a control unit in the form of a magnifying observation processing device that acquires the region of interest from scanning results and conducts observation or processing. The control unit ensures that the marker, indicating the outer edge of the observed region, is formed in a specific region that aligns with the region of interest and the scaling center. The interaction between the needle and the sample is crucial for marker formation, with the marker's position designed to match the visual field size for efficient marker search. Additionally, the patent details various conditions for marker formation, such as line direction, length, thickness, and drawing speed, to optimize the observation process.
