This paper presents a joining method by using the silicon wafer in order to apply to joint to the 3-dimensional structures of semiconductor device, high-speed , high integration, micro machine, silicon integrated sensor, and actuator. In this study, the high atomic beam, stabilized by oxidation film and organic materials at the material surface, is investigated, and the purified is obtained by removing the oxidation film and pollution layer at the materials. And the unstable surface is obtained, which can be easily joined. In order to use the low temperatures for the joint method, the main subjects are obtained as follows: 1) In the case of the silicon wafer and the silicon wafer and the silicon wafer of alumina sputter film, the specimens can be jointed at 2$0^{\circ}C$, and the joining strength is 5Mpa. 2) The specimens can not always be joined at the room temperatures in the case of the silicon wafer and the silicon wafer of alumina sputter film.
