The  process  includes  the  steps  of forming a first storage node on the substrate where  a  transistor is formed thereon forming a first dielectric layer on the  surface of the first storage node and on the predetermined portion of  the impurity region of the transistor adjacent to first storage  node, forming a common plate electrode on the  first  dielectric  layer, forming a second dielectric layer on the  surface  of  the  common plate electrode, depositing a third polysilicon on  the  resultant and patterning a third polysilicon layer to form a second  storage node.  Capacitance  is  increased  by  connecting  the  capacitors parallel.

Abstract: The method for preventing the generation of short channel effect comprises the steps of growing a SiO2 film (2) and a P epitaxial layer (3) on a substrate (1), forming trenches into the epitaxial layer (3) by using a photo and etching process, forming a field oxide film (4) for mask on the trench to incline the epitaxial portion (3) to be formed as a gate by using a photo and etching process, forming a gate oxide film (5), a gate polysilicon film (6) and a silicide film (7) to form a gate by using a photo and etching process, implanting low concentration of ions for the source and drain into the substrate, growing and etching a LTO film to form a side wall spacer (8), and implanting high concentration of ions for source and drain junction into the substrate.
