Abstract:
PURPOSE: A non-volatile memory device having stack structure, memory card, and an electronic system are provided to simplify the wiring and layout of a core circuit unit and a bottom signal line. CONSTITUTION: A laminated NAND cell array(250) is formed on a substrate(210). The laminated NAND cell array comprises a NAND strings which are perpendicularly laminated on the substrate. A plurality of signal lines(230) are combined in the laminated NAND cell array. Signal lines are formed on the bottom of laminated NAND cell array or are formed on the substrate into which an insulating layer is inserted. The signal lines are electrically connected with the laminated NAND cell array. The laminated NAND cell array is connected to the signal lines through a plurality of perpendicular plugs(240).
Abstract:
A manufacturing method of a semiconductor integrated circuit device is provided to steadily fill up the recess with the semiconductor layer without generating the void in the recess. A manufacturing method of a semiconductor integrated circuit device comprises a step for forming the first insulating layer(110); a step for forming the semiconductor layer; a step for forming the second insulating layer; a step for partly removing the semiconductor layer, a step for removing the second insulating layer; a step for performing an optional epitaxial process(140) in the semiconductor layer. The first insulating layer includes the recess. The semiconductor layer covers the recess.
Abstract:
PURPOSE: A method for manufacturing a memory device is provided to prevent the leakage current of a blocking dielectric film by suppressing the interfacial reaction of an silicon oxide in a first dielectric film and an aluminum oxide in a third dielectric film. CONSTITUTION: A tunnel dielectric film(110) is formed on a substrate(10). An electric charge trapping film(120) is formed on the tunnel dielectric film. A blocking dielectric film(130) is formed on the electric charge trapping film. A first dielectric film(131) including a silicon oxide is formed on the electric charge trapping film. A second dielectric film(133) including an aluminum silicate is formed on the first dielectric film. A third dielectric layer(135) including an aluminum oxide is formed on the second dielectric film.
