Abstract: A new high density vertical trench transistor and trench capacitor DRAM (dynamic-random-access memory) cell is described incorporating a wafer with a semiconductor substrate (10) and an epitaxial layer (10) thereon including a vertical transistor (14) disposed in a shallow trench (100) stacked above and self-aligned with a capacitor in a deep trench (16). The stacked vertical transistor (4) has a channel partly on the horizontal surface and partly along the shallow trench sidewalls. The drain of the access transistor (14) is a lightly-doped drain structure (21) connected to a bitline element (22). The source (24) of the transistor, located at the bottom of the transistor trench (100) and on top of the center of the trench capacitor (16), is self-aligned and connected to polysilicon (28) contained inside the trench capacitor. Three sidewalls of the access transistor (14) are surrounded by thick oxide isolation (50) and the remaining one side is connected to drain and bitline contacts. The memory cell is located inside an n-well (26) and uses the n-well and heavily-doped substrate (10) as the capacitor counter-electrode plate. The cell storage node is the polysilicon (28) inside the trench capacitor. The fabrication method includes steps for growing epitaxial layers wherein an opening (100) is left which serves as the shallow trench access transistor region and provides self-­alignment with the deep trench storage capacitor.

Abstract: The invention relates to a process for manufacturing thin layers of material of an oxide-containing high-temperature superconductor. In this process, the material is used as target material having the stoichiometric composition of the superconductor. The layers are formed by eroding target material with the aid of a laser and forming a deposit on a heated substrate. The object of the invention is to provide a simple manufacturing process which does not require the process steps of post-treating the layers. This is achieved in that the layers are formed under an oxygen partial pressure of at least 0.1 mbar with a substrate surface temperature in the range between 600 DEG C and 900 DEG C. The temperature of the substrate surface is expediently adjusted to a value at which the formation of layers having superconducting properties is optimum. <IMAGE>
