    摘要: In one embodiment, a plurality of gate structures including gate electrodes and insulating layers covering the gate electrodes are formed on a semiconductor substrate. Impurity ions at a low dose for forming a source/drain region are implanted into the semiconductor substrate, using the gate structures as a mask. First insulating spacers are formed on the sidewalls of the gate structures and second insulating spacers are formed on the first insulating spacers. Thereafter, impurity ions at a high dose are implanted into the semiconductor substrate, using the first and second insulating spacers as a mask. Then, the second insulating spacers are removed. Therefore, contact resistance and characteristics of the transistors can be improved by adjusting an effective channel length and contact areas.

    摘要: A conductive portion connects a lower conductive layer formed on a semiconductor substrate provided in a first interlayer insulating layer to an upper conductive layer formed on the lower conductive layer, and provided in a second interlayer insulating layer. This portion is divided into at least one plug and a pad. At least one plug is formed in a first interlayer insulating layer and the lower part of a second interlayer insulating layer. The second interlayer insulating layer is divided into a plurality of interlayer insulating layers so that upper and lower widths of the divided plugs formed in the divided portion of the second interlayer insulating layer are not greatly different from each other. The pad formed on the upper portion of the second interlayer insulating layer has an upper width such that the upper conductive layer connected to the pad is not undesirably connected to an adjacent upper conductive layer via the pad.

    摘要: An etch-stop layer is selectively provided between layers of a multiple-layered circuit so as to allow for outgassing of impurities during subsequent fabrication processes. The etch-stop layer is formed over an underlying stud so as to serve as an alignment target during formation of an overlying stud formed in an upper layer to be coupled to the underlying stud. In this manner multiple-layered circuits, for example memory devices, can be fabricated in relatively dense configurations.

    摘要: Methods are provided for operating a magnetic random access memory device including a memory cell having a magnetic tunnel junction structure on a substrate.
