    摘要： Methods of forming an integrated circuit device may include forming an insulating layer on an integrated circuit substrate, forming a first conductive layer on the insulating layer, and forming a second conductive layer on the first conductive layer so that the first conductive layer is between the second conductive layer and the insulating layer. Moreover, the first conductive layer may be a layer of a first material, the second conductive layer may be a layer of a second material, and the first and second materials may be different. A hole may be formed in the second conductive layer so that portions of the first conductive layer are exposed through the hole. After forming the hole in the second conductive layer, the first and second conductive layers may be patterned so that portions of the first and second conductive layers surrounding portions of the first conductive layer exposed through the hole are removed while maintaining portions of the first conductive layer previously exposed through the hole.

    摘要： A semiconductor device comprises bit line landing pads and storage landing pads disposed on both sides of the bit line landing pads overlying a substrate. A bit line interlayer insulating layer overlies the bit line and storage landing pads. A plurality of bit line patterns are disposed on the bit line interlayer insulating layer. The bit line patterns each include a bit line and a bit line capping layer pattern. Line insulating layer patterns are placed on a top surface of the bit line interlayer insulating layer. Upper contact holes are placed in a region between the bit line patterns and higher than upper surfaces of the bit lines. Contact hole spacers cover the side walls of the upper contact holes. Lower contact holes are self-aligned with the upper contact holes and extend through the line insulating layer patterns and the bit line interlayer insulating layer, thereby exposing the storage node landing pads.

    摘要： A method of manufacturing a semiconductor device with contact bodies that extend in the direction of bit lines to contact storage nodes includes forming band-type openings by selectively etching an insulating layer that covers the bit lines. The band-type openings extend in a lengthwise direction of the gate lines to expose the first contact pads and have portions that protrude in a lengthwise direction of the bit lines. The method also includes forming a conductive layer on the insulating layer that fills the band-type openings and is electrically connected to the first contact pads. The conductive layer is then patterned to separate the conductive layer into individual storage node contact bodies that extend in a lengthwise direction of the bit lines. Storgage nodes are then formed on the storage node contact bodies.

    摘要： An MRAM device may include semiconductor structures, a common source region, a drain region, a channel region, gate structures, word line structures, MTJ structures, and bit line structures arranged on a substrate. Each of the semiconductor structures may include a first semiconductor pattern having a substantially linear shape extending in a first direction that is substantially parallel to a top surface of the substrate, and a plurality of second patterns that each extend in a third direction substantially perpendicular to the top surface of the substrate. A common source region and drain region may be formed in each of the semiconductor structures to be spaced apart from each other in the third direction, and the channel region may be arranged between the common source region and the drain region. Gate structures may be formed between adjacent second semiconductor patterns in the second direction. Word line structures may electrically connect gate structures arranged in the first direction to each other. MTJ structures may be electrically connected to corresponding ones of the second semiconductor patterns. Each bit line structure may electrically connect two adjacent MTJ structures in the first direction to each other.
