  • Patent number: 10672622
    Abstract: An etching method includes loading, first and second supplying, removing and etching steps. In the loading step, a target object is loaded into a chamber. In the first supply step, a first gas containing carbon, hydrogen and fluorine is supplied into the chamber. In the modification step, plasma of the first gas is generated to modify a surface of a mask film and a surface of an organic film which is not covered with the mask film. In the second supply step, a second gas for etching the organic film is supplied into the chamber. In the removal step, a modified layer formed on the surface of the organic film is removed by applying a first high frequency bias power. In the etching step, the organic film below the modified layer is etched by applying a second high frequency bias power lower than the first high frequency bias power.

  • Patent number: 10534298
    Abstract: In a displacement sensor, an illumination optical system, which converts laser light emitted from an emission unit into first converging light, and irradiates with the first converging light a detection space through which a target moves. An imaging optical system converts laser light reflected from the target into second converging light, and irradiates with the second converging light a light-receiving surface of a detection unit. The image of the emission unit into which the illumination optical system focuses the first converging light is displaced along the optical axis of the imaging optical system by a temperature change of the illumination optical system. The range in which the image is displaced is limited to be located either anterior to the front principal point of the imaging optical system, or posterior to the rear principal point of the imaging optical system.
