Scanning prove microscope （SPM） has been regards as an important tool to investigate the surface structure and physical and chemical properties. In the last decade, the applications of SPM technologies have been widely developed in various scientific applications. One of the major applications is the development of multi-proves SPM. Those different probes equipped in Multi-prove SPM are able to independently approach the quasi-nano size samples under SEM or optical microscope that can help us to directly measure the local physical and chemical properties. Due to some properties are sensitive to the cleanness of sample surface and thermal effect, the multi-probes SPM measurement is suggested to perform under UHV and low temperature environment.
