Progress of our new low temperature ultrahigh vacuum scanning tunneling microscope (STM) will be presented. Lateral manipulation of single magnetic atoms such as dysprosium and holmium on the Ag(100) and Ag(110) surfaces was carried out using an STM tip. Single inorganic molecules such as fluorinated copper phthalocyanine (F16CuPC) on the silver surfaces were detected using STM spectroscopy and were manipulated. We are also developing a new scheme to implement a tuning fork style atomic force microscope (AFM) capability as well as STM routines. Some of our key instrument concepts such as an exchangeable low temperature preamplifier will be presented. This AFM function will enable studying elementary chemical reactions involving single atoms and single molecules not only on conducting surfaces, but also on insulating surfaces. This capability of tuning fork AFM together with STM manipulation and spectroscopy routines are important to realize “angstrom-chemistry” of single atoms and single molecules.
