    摘要: A DRAM device includes a substrate including an active region having an island shape and a buried gate pattern. A mask pattern is over an upper surface portion of the substrate between portions of the buried gate pattern. A capping insulating layer fills a gap between portions of the mask pattern. A first pad contact penetrates the capping insulating layer and the mask pattern, and contacts a first portion of the substrate in the active region. Second pad contacts are under the capping insulating layer, and contact a second portion of the substrate in the active region positioned at both sides of the first pad contact. A spacer is between the first and second pad contacts to insulate the first and second pad contacts. A bit line configured to electrically connect with the first pad contact, and a capacitor configured to electrically connect with the second pad contacts, are provided.

    摘要: In a method of forming a conductive layer structure and a method of manufacturing a recess channel transistor, a first insulating layer and a first conductive layer are sequentially formed on a substrate having a first region a second region and the substrate is exposed in a recess-forming area in the first region. A recess is formed in the recess-forming-area by etching the exposed region of the substrate. A second insulating layer is conformally formed on a sidewall and a bottom of the recess. A second conductive layer pattern is formed on the second insulating layer to fill up a portion of the recess. A spacer is formed on the second conductive layer pattern and on the second insulating layer on the sidewall of the recess. A third conductive layer pattern is formed on the second conductive layer pattern and the spacer to fill up the recess.

    摘要: In methods of manufacturing a DRAM device, a buried-type gate is formed in a substrate. A capping insulating layer pattern is formed on the buried-type gate. A conductive layer pattern filling up a gap between portions of the capping insulating layer pattern, and an insulating interlayer covering the conductive layer pattern and the capping insulating layer pattern are formed. The insulating interlayer, the conductive layer pattern, the capping insulating layer pattern and an upper portion of the substrate are etched to form an opening, and a first pad electrode making contact with a first pad region. A spacer is formed on a sidewall of the opening corresponding to a second pad region. A second pad electrode is formed in the opening. A bit line electrically connected with the second pad electrode and a capacitor electrically connected with the first pad electrode are formed.

    摘要: An isolation layer having a first depth is formed from an upper face of a substrate. Source/drain regions including junctions are formed in the substrate. Each of the junctions has a second depth substantially smaller than the first depth. A first recess is formed in the substrate by a first etching process. A protection layer pattern is formed on a sidewall of the first recess. A second recess is formed beneath the first recess. The second recess has a width substantially larger than that of the first recess. The second recess is formed by a second etching process using an etching gas containing an SF6 gas, a Cl2 gas and an O2 gas. A gate insulation layer is formed on surfaces of the first and the second recesses. The second recess having an enlarged shape may reduce a width of the junction between the gate electrode and the isolation layer so that a leakage current generated through the junction may decrease.

    摘要: In an embodiment, a simplified method of manufacturing a semiconductor device reduces a step between cell and peripheral areas. First and second openings are formed through a plurality of thin layers including a support layer on a substrate. A storage electrode and a guide ring are formed on sidewalls and bottoms of the first and second openings, respectively. A support pattern is formed so that the support layer in the cell area is partially etched and the support layer in the peripheral area remains un-etched, thus the support pattern supports and surrounds the storage electrodes adjacent to each other in the cell area and prevents an etching of a layer underlying the support layer in the peripheral area. A dielectric layer and a plate electrode are formed on the storage electrode to complete a semiconductor device with the reduced step.
