Patent ID: 8866306

Claim:
A semiconductor device, comprising: a signal conductor layer having a first signal track set defined by a first mask and a second signal track set defined by a second mask, the first signal track set having a first quality characteristic and the second signal track set having a second quality characteristic; a first signal path comprising: a first signal track segment from the first signal track set having a first length; a second signal track segment from the second signal track set having a second length; a third signal track segment from the first signal track set having the first length; a first repowering block adapted to transfer the first signal path from the first signal track segment to the second signal track segment; a second repowering block adapted to transfer the first signal path from the second signal track segment to the third signal track segment; and when the first quality characteristic is greater than the second quality characteristic the first signal track segment is longer than the second signal track segment, when the second quality characteristic is greater than the first quality characteristic the second signal track segment is longer than the first signal track segment, and when the first quality characteristic is substantially equal to the second quality characteristic the first and second signal track segment lengths are discretionary.
