Patent ID: 7932733

Claim:
An apparatus for detecting defect comprising: a sample stage that holds a sample; an electron optical system that observes the sample on the sample stage; a probe device that includes a probe contacted with the sample on the sample stage; an electric characteristic measuring device that measures electric characteristics of a probe contact point of the sample through the probe; a driving device that drives the sample stage; a heater that is provided in the sample stage and heats the sample stage; a first heat transfer portion that is connected to the sample stage; a sample chamber which is a vacuum chamber that accommodates the sample stage, the probe device, the driving device, the heater, and the first heat transfer portion therein and includes an observation/measurement position where the electron optical system observes the sample and the electric characteristic measuring device measures the electric characteristics of the sample, and a probe replacement position where the probe is replaced, in its inner space; a second heat transfer portion that is connected to the first heat transfer portion when the sample stage is disposed at the observation/measurement position and is separated from the first heat transfer portion to release the restriction of the sample stage when the sample stage is moved to the probe replacement position; and a refrigerant storage that is connected to the second heat transfer portion.
