A new-style STM is presented. With its automatic advancing, braking and locking devices, it can achieve the tunneling state semi-automatically. Scanning programmed makes it work more quickly. A special software is used to manipulate the imagines. This gives us a better way to know the information of the surface of the specimen. By comparing typical images obtained with the acknowledged ones, its resolving capability given transverse is 0.1 nm, and vertical is 0.01 nm. Several images are given as samples.
