IPC: G01Q10/00
Filed: 2019-04-19
Abstract: The present invention relates to a smart automation sample stage used to stably place a sample when scanning the sample surface using an atomic force microscope. In order to solve a disadvantage of having to refocus finely whenever an observation area is moved when the surface of the sample is not flat during an experiment, the present invention implements a new sample stage equipped with an X-Y coordinate control function and a rotation function and at the same time adding a 360° omnidirectional tilt control function. Therefore, a more efficient and accurate experiment is possible, such as allowing smooth observation without fine focus adjustment after adjusting the surface to be flat using the tilt control function in a case of the sample whose surface is inclined in one direction. Meanwhile, the new sample stage with the X-Y coordinate control function, the rotation function, and the 360° omnidirectional tilt control function as well as an automatic coordinate tracking function is implemented. Therefore, efficiency of the experiment can be further improved, such as automatically adjusting the position of the sample to the existing observation area after the rotation without a need to manually adjust the position of the sample to find the existing observation area if a part which comes within the field of view of a lens changes after rotation of the sample. The smart automation sample stage comprises an X actuator (12), a Y actuator (14), a tilt rotation actuator (18), and a tilt actuator (22).
