    Abstract: An inspection device improves accuracy characteristics of an (MRAM), the inspection device including a stage on which a MRAM element is fixed, and electromagnets generating a first magnetic field. A magnetic field having a component in a direction perpendicular to the stage is changeable from a first direction to a second direction according to a position on the stage. A second magnetic field in which a direction of a magnetic field component is parallel to the stage changes from a third direction to a fourth direction according to the position on the stage, an optical system illuminating the MRAM element with light including polarized light, and condensing reflected light from reflected illumination light from the MRAM element, and a detector detecting reflected light when the position of the MRAM element is changed, and when the position of the MRAM element in the second magnetic field is changed.

    Abstract: A measuring system measures an overall resistance of two or more films on a substrate/measurement object by a terahertz absorption measurement and an overall film thickness by a photoacoustic measurement. The system estimates a first film thickness based on the overall resistance, then subtracts this estimated thickness from the overall film thickness measured by the photoacoustic measurement. The system includes a source unit to output a laser beam. A first pump-probe unit receives the laser beam and performs a photoacoustic test on the measurement object. A second pump-probe unit receives the laser beam and performs a terahertz signal test on the measurement object. The system also includes a stage to support the measurement object and controls for controlling elements and calculating the film thicknesses
