Abstract: The dynamic random access  memory  has  trench  type  storage capacitors using silicon on insulation structure (SIO).  A  source of translation trnsistor and an electrode of storage capacitor are connected without contact to improve the  arrangement  efficiency. The method comprises: (A) forming an activated region  on  surface silicon layer of the SOI wafer;  (B)  vaporizing  silicon  oxicide (43), silicon nitride (49) and silicon oxcide (50) to form a mask; (C) forming a  trench  by  etching  the  vaporized  surface  using reactive ion etching method and  vaporizing  multicrystal  silicon and silicon nitride; (D) doping the trench by  Boron  through  the mask; and (E) connecting bit lines to  connect  channel  electrode (59) and source (71).
