  • Patent number: 6790750
    Abstract: A semiconductor device includes a wafer having a semiconductor layer with source, body and drain regions. A electrically-conducting region of the semiconductor region overlaps and electrically couples the source region and the body region. The electrical coupling of the source and body regions reduces floating body effects in the semiconductor device. A method of constructing the semiconductor device utilizes spacers, masking, and/or tilted implantation to form an source-body electrically-conducting region that overlaps the source and body regions of the semiconductor layer, and a drain electrically-conducting region that is within the drain region of the semiconductor layer.

  • Publication number: 20040175922
    Abstract: The present invention provides a method for forming a low-k dielectric structure on a substrate 10 that includes depositing, upon the substrate, a dielectric layer 12. A multi-film cap layer 18 is deposited upon the dielectric layer. The multi-film cap layer includes first 181 and second 182 films, with the second film being disposed between the dielectric layer and the first film. The first film typically has a removal rate associated therewith that is less than the removal rate associated with the second film. A deposition layer 20 is deposited upon the multi-film cap layer and subsequently removed. The properties of the multi-film cap layer are selected so as to prevent the dielectric layer from being exposed/removed during removal of the deposition film. In this manner, a deposition layer, having variable rates of removal, such as copper, may be planarized without damaging the underlying dielectric layer.

  • Patent number: 6787436
    Abstract: Methods for reducing the contact resistance presented by the interface between a silicide and a doped silicon region are presented. In a first method, a silicide layer and a doped silicon region form an interface. Either a damage-only species or a heavy, metal is implanted through the silicide layer into the doped silicon region immediately adjacent the interface. In a second method, a second metal is added to the refractory metal before formation of the silicide. After annealing the refractory metal and the doped silicon region, the second metal diffuses into the doped silicion region immediately adjacent the interface without forming additional phases in the silicide.

  • Patent number: 6788583
    Abstract: A method of detecting a charge stored on a charge storage region of a first dual bit dielectric memory cell within an array of dual bit dielectric memory cells comprises grounding a first bit line that forms a source junction with a channel region of the first memory cell. A high voltage is applied to a gate of the first memory cell and to a second bit line that is the next bit line to the right of the first bit line and separated from the first bit line only by the channel region. A third bit line, that is the next bit line to the right of the second bit line, is isolated such that its potential is effected only by its junctions with the a second channel region and a third channel region on opposing sides of the third bit line. A high voltage is applied to a pre-charge bit line that is to the right of the third bit line and current flow is detected at the second bit line to determine the programmed status of a source bit of the memory cell.
