Provided is a method and a device for measuring a temperature which can recognize the temperature of a semiconductor layer directly with high precision when the semiconductor layer is formed by deposition. The quantity of laser light transmitted a semiconductor layer is monitored by a photodetector by using laser light having a wavelength λs at which the transmittance of light changes abruptly when the temperature of the semiconductor layer reaches Ts during or after deposition. When heat being given to the semiconductor layer is changed, the quantity of laser light monitored by the photodetector changes abruptly when the temperature of the semiconductor layer reaches Ts at a time A, B or C. Consequently, the fact that the temperature of the semiconductor layer reached Ts at a time A, B or C can be recognized exactly, and an error in temperature information observed by a device for measuring temperature variations can be calibrated, for example.

A defective particle measuring apparatus that irradiates focused laser light on a sample 14, images scattered light from the sample 14, and measures defective particles in the sample 14 based on the image result, includes a position deviation computing portion 31 which, based on an in-plane intensity distribution of scattered light of each defective particle that is imaged, obtains a deviation from a focal point position on an image point side of the scattered light of each defective particle and calculates a position deviation amount in a depth direction of the defective particle corresponding to the deviation from the focal point position, a light intensity correcting portion 32 for correcting the light intensity of the scattered light of the defective particle corresponding to the position deviation amount in the depth direction, and a size determining portion 33 for determining the defective particle size based on the light intensity corrected by the light intensity correcting portion 32. Thus, the size of the defective particles can be determined at a high precision by a simple constitution in a short time, and density distribution of the defective particles can be obtained.
