  • Patent number: 8361856
    Abstract: A memory cell includes a vertically oriented transistor having an elevationally outer source/drain region, an elevationally inner source/drain region, and a channel region elevationally between the inner and outer source/drain regions. The inner source/drain region has opposing laterally outer sides. One of a pair of data/sense lines is electrically coupled to and against one of the outer sides of the inner source/drain region. The other of the pair of data/sense lines is electrically coupled to and against the other of the outer sides of the inner source/drain region. An access gate line is elevationally outward of the pair of electrically coupled data/sense lines and is operatively adjacent the channel region. A charge storage device is electrically coupled to the outer source/drain region. Other embodiments and additional aspects, including methods, are disclosed.

  • Publication number: 20120329274
    Abstract: The present invention proposes the use of a silicon nitride layer on top of a second conductive layer. After a step of etching a second conductive layer, an oxide spacer is formed to define a gap. Then, another silicon nitride layer fills up the gap. After that, the oxide spacer is removed. Later, a first conductive layer is etched to separate the digit line to cell contact line.

  • Publication number: 20100090348
    Abstract: An integrated circuit is manufactured from a semiconductor substrate having trenches with first and second sidewalls facing each other and a conductive line arranged in a bottom region of the trenches. At least the bottom region of the trenches is lined with an insulative material between the conductive line and the substrate. A first sacrificial layer is formed above the conductive line adjacent the first and second sidewalls. The trenches are filled with one or more additional sacrificial layers having a different etch selectivity than the first sacrificial layer. A portion of the one or more additional sacrificial layers and a portion of the insulative material are selectively removed to the first sacrificial layer so that the substrate is exposed below the first sacrificial layer along the first trench sidewalls and covered by the insulative material along the second trench sidewalls.

  • Publication number: 20070032032
    Abstract: A method for manufacturing a surface strap connection between a trench capacitor and a selection transistor includes providing a masking material on a surface of a semiconductor substrate in areas where no trench capacitors have been formed. An undoped semiconductor layer having vertical and horizontal areas is applied. An oblique ion implantation is performed such that a vertical area of the semiconductor layer on which the connecting structure is to be formed is not doped. After removal of the undoped portion of the semiconductor layer, the exposed portion of the masking material is laterally etched, one part of the substrate surface is exposed, and the doped part of the semiconductor layer is removed. An electrically conducting connection material is applied so that an electrical contact exists between the exposed portion of the substrate surface and the storage electrode.
