  • Patent number: 6855597
    Abstract: A method of manufacturing a DRAM cell includes forming an isolation layer on a given region of a substrate to define an active region having a plurality of line shaped sub-regions; forming at least a pair of cell transistors in each line shaped sub-region, each cell transistor of a pair having a common drain region and respective source regions; forming a bit line pad on each common drain region and a storage node pad on each source region; forming a bit line pad protecting layer pattern having portions parallel to the word line, that covers the bit line pad; and forming storage nodes on storage node pads. The storage nodes of the DRAM cell contact with the storage node pads and are insulated electrically from the bit line pad by the bit pad protecting layer pattern.

  • Patent number: 6391714
    Abstract: A method for making a capacitor of a semiconductor memory device capable of providing increased capacitance without degraded resolution, as well as without the removal of any interlayer insulation layers upon formation of a lower electrode for the capacitor, wherein after formation of an access transistor on a semiconductor substrate, a first interlayer insulation layer for planarization of a surface of the semiconductor substrate and a second interlayer insulation layer for formation of the capacitor lower electrode are formed. After formation of an opening for exposing a part of an impurity diffusion region of the access transistor by etching a part of the first and second interlayer insulating layers, a spacer is formed within the opening. Further, after deposition of a conductive layer for the capacitor lower electrode onto a surface of the substrate, a planarization process is carried out until a part of the upper surface of the spacer is exposed.

  • Patent number: 5399518
    Abstract: A method for manufacturing a double-cylindrical storage electrode of a capacitor of a semiconductor memory device, utilizes an outer etching mask for forming an outer cylinder and an inner etching mask for forming an inner cylinder. After forming a conductive structure on a semiconductor substrate, an outer etching mask for forming an outer cylinder and an inner etching mask for forming an inner cylinder are formed on the conductive structure. Then, the conductive structure is anisotropically etched using the outer and inner etching masks, thereby forming a double-cylindrical first electrode. Since a double-cylindrical storage electrode can be obtained from a single conductive layer, the influence of native oxidation circumvented. In addition, the double-cylindrical storage electrode of the capacitor according to the present invention decreases the risk of structural fragmenting because the electrode is obtained from one material layer, instead of a combination of layers as is conventionally-known.

  • Patent number: 5317534
    Abstract: A method for manufacturing highly integrated NAND and NOR logic mask read only memory (MROM) devices is disclosed. Over the top surface of a semiconductor substrate, where a first polysilicon layer is formed, a pattern of a gate electrode is formed along a word line in the order of odd numbers or even numbers. Next, an insulation layer having a thickness of a submicron range is formed over the top surface of the substrate. And then a photoresist is covered and an etch back process is performed. Thereafter, the exposed insulation layer caused by the etch back process and the polysilicon layer are selectively etched to form a word line spacing corresponding to a thickness of the insulation layer. Thus, spacing between adjacent word lines can be minimized and a process margin can be sufficiently ensured.
