Abstract:
1. In a regular array of contact sites spaced apart on a substrate by a distance of one pitch in at least first and second directions, a plurality of contacts comprising: a plurality of ground contacts located at certain of said contact sites and spaced apart by three pitch distances in said first and second directions; and a plurality of pairs of differential contacts, each contact located at a contact site, the contacts of each pair spaced apart from each other by one pitch distance, one contact of each pair of differential contacts being located in the array one pitch distance away from a ground contact and the other contact of each pair being located no more than approximately sqrt(2)*pitch distance away from the same ground contact and no two differential pairs being located in the array so that they are parallel to one another with each contact of one pair located one pitch distance away from a corresponding contact of the other pair.
