A microelectronic element such as a chip or microelectronic wiring
substrate is provided which includes a plurality of conductive
interconnects for improved resistance to thermal stress. At least some of
the conductive interconnects include a metallic plate, a metallic
connecting line and an upper metallic via. The metallic connecting line
has an upper surface at least substantially level with an upper surface
of the metallic plate, an inner end connected to the metallic plate at
one of the peripheral edges, and an outer end horizontally displaced from
the one peripheral edge. The metallic connecting line has a width much
smaller than the width of the one peripheral edge of the metallic plate
and has length greater than the width of the one peripheral edge. The
upper metallic via has a bottom end in contact with the metallic
connecting line at a location that is horizontally displaced from the one
peripheral edge by at least about 3 microns (.mu.m).
