ABSTRACT:
Nitrogen atoms on the surface of a first body are terminated by hydrogen atoms after the surfaces of the first body and a second body to which it is to be bonded are cleaned. The surface of the first body terminated by the hydrogen atoms and the surface of the second body are bonded to each other so that hydrogen bonds are formed between the nitrogen atoms and the bonded hydrogen atoms on the surface of the first body and the atoms on the surface of the second body. Using these hydrogen bonds, the surface of the first body and the surface of the second body are strongly bonded to each other. When the surface of the second body is formed with nitride or oxide, strong hydrogen bonds of N--H .sup.- - - N or N--H .sup.- - - O are formed between the first body and the second body. Thus, the method does not require bonding under high temperature or high pressure.
