This paper describes a novel scanning tunnling microscope (STM) system usinga two-dimensional monolithic Paranel spring (MPS) and piczo-electric actuators (PZT)for precision two-dimensional positioning. This leads the interference between the x-axisdisplacement and the y-axis to be very small. The PZT used for controlling the z-axisdisplacement and the sample-to-tip distance is mounted on the monolithic parallel spring.Therefore, the mutual interference to z-axis displacements is negligible.
