Appeal 2007-1711
Application 10/657,898
Yonesaka and Chua, respectively, do not cure the deficiency of Mori.
Appellants present no further arguments. The Examiner (Answer 3-4)
asserts that Figure 3 of Mori shows the claimed supply interconnect grids
being rotated relative to each other. The issue, therefore, is whether for
claims 1 through 3 and 6 through 10 the combination of Mori and Yonesaka
and for claims 11 through 13, 16, and 17 the combination of Mori,
Yonesaka, and Chua discloses the grid of supply interconnects of a first one
of the plurality of voltage supply structures being rotated relative to the grid
of supply interconnects of a second one of the voltage supply structures.
Mori discloses (col. 4, l. 39-col. 5, l. 6) a power wiring layer 310 for
power conductive line 311, an insulating layer 320, a power/ground wiring
layer 330 for power conductive lines 331 and ground conductive lines 332,
another insulating layer 340, ground wiring layer 350 for ground conductive
lines 352, a third insulating layer 360, and signal wiring layer 370 for signal
conductive lines 371-373. Thus, the three topmost metallization layers have
voltage supply structures and the lower metallization layers have signal line
structures. As shown in Figure 3, power conductive lines 331 (the claimed
second one of the voltage supply structures for a high supply potential) are
parallel to each other and perpendicular to ground conductive lines 352 (the
claimed first one of the voltage supply structures for a low supply potential).
Thus, Mori shows "said grid of supply interconnects of said first one of said
plurality of voltage supply structures being rotated relative to said gird of
supply interconnects of said second one of said plurality of voltage supply
structures," as recited in independent claims 1 and 11. Since Appellants
presented no further arguments, we will sustain the obviousness rejection of
