The storage electrode, the dielectric film of the capacitor, the plate electrode, which are created through the storage electrode contact window, could be electrically connected to the first semiconductor substrate to form the capacitor. After combining the first semiconductor substrate provided with an oxide film and the second semiconductor substrate loaded with a wafer, the first semiconductor substrate is etched for planarization until the trench is isolated and exposed. After the planarization and etching, on the first semiconductor substrate, there is formed the joining region transistor with wordline; and on the upper portion of the wordline, there is formed the bitline which electrically connecting to the joint region. By using the method of forming the high density semiconductor memory device on the SOI substrate, the size of the isolated space used for separating the area consumption between the well regions and the size of the chip could be reduced. Besides, it could minimize the influence of the joint capacitor and the joint leakage current toward the device by forming the high density semiconductor memory device on the SOI substrate. Through the formation of the transistor on the memory cell capacitor, it could prevent from having the bad characteristic of the transistor. Furthermore, it could simplify the process by using the insulating material surrounded active region used in the trench etching mask and the trench isolation; and could prevent the bad characteristic of the trench isolation happened in the process of removing the trench etch mask. In addition, it could, as the COB structure, assure the area of the cell capacitor, and, as the COB structure, make the planarization process easier.
