Abstract: An eDRAM and a method for making it are disclosed. In the method, a pad oxide layer and a pad nitride layer formed over a surface of a substrate are removed after an active area and a deep trench filled with polysilicon are formed, followed by the formation of a re-deposited oxide layer and a re-deposited nitride layer. The re-deposited nitride layer has greater uniformity than the pad nitride layer that has undergone the formation of the deep trench. An isolation recess and a recess extension are then formed at one side of the deep trench and then filled with an isolation dielectric. In this process, the re-deposited nitride layer can be utilized to control the height and flatness of a top surface of the isolation dielectric, thus ensuring effective isolation of the polysilicon from a word line.
