Abstract:
The present invention relates to a probe station which is electric analysis equipment for an electrical and electronic device component, comprising: a box-shaped case having an enclosed structure; a chuck mounted inside the case for fixedly placing the device component thereon; a chuck drive stage for moving independently the chuck in left/right and forward/rearward directions; a probe for probing a sample of the device component; a holder coupled to the probe; a probe drive stage for externally controlling the holder to be moved in a vertical and horizontal direction; an optical microscope mounted above the top surface of the case for observing a contact between the device component and the probe; a microscope control stage for controlling the position of the optical microscope in left/right and forward/rearward directions; an openable/ closable transparent window mounted on the top surface and the front surface of the case so as to observe the inside of the case; a connection tube for enabling inflow and outflow of gas into and out of the case; and a probe connecting line for transferring an electrical control signal outputted from the probe to an analysis unit therethrough.
Abstract:
An apparatus for scattering glancing angle incidence of radiation light is provided to obtain data by precisely controlling an incidence angle of the radiation light. An apparatus for scattering glancing angle incidence of radiation light includes a sample installation unit(100), a sample control unit(110), a temperature adjustment unit(120), and a main control unit(130). A thin film sample for analyzing a structure is located on the sample installation unit(100) which is scattered in response to the input radiation light. The thin film sample(100) outputs a scattered signal. The sample control unit(110) controls a position of the sample installation unit(100) for the radiation light and an incidence angle of the radiation light. The temperature adjustment unit(120) adjusts a temperature of the sample installation unit(100). The main control unit(130) transmits a control command to the sample control unit(110) and the temperature adjustment unit(120), stores and displays the control command and the control result.
