Methods are provided for reducing the aspect ratio of contacts to bit
lines in fabricating an IC including logic and memory. The method
includes the steps of forming a first group of device regions to be
contacted by a first level of metal and a second group of memory bit
lines to be contacted by a second level of metal, the first level
separated from the second level by at least one layer of dielectric
material. Conductive material is plated by electroless plating on the
device regions and bit lines and first and second conductive plugs are
formed overlying the conductive material. The first conductive plugs are
contacted by the first level of metal and the second conductive plugs are
contacted by the second level of metal. The thickness of the plated
conductive material provides a self aligned process for reducing the
aspect ratio of the conductive plugs.
