Patent ID: 7372072

Claim:
A semiconductor wafer, comprising: a plurality of first sawing regions extending in a first direction; a plurality of second sawing regions extending in a second direction, the second direction extending transversely with respect to the first direction; a plurality of useful regions arranged between respective adjacent first sawing regions and respective adjacent second sawing regions, each useful region including an integrated circuit; test structures arranged in one of the first sawing regions and/or one of the second sawing regions, the test structures suitable for providing a signal representing an electrical parameter; connection contacts electrically connected to the test structures, the connection contacts being arranged in said one of the first sawing regions and/or one of the second sawing regions, one portion of the connection contacts being arranged in a first row running along a first direction, and a further portion of the connection contacts being arranged in a second row running along the first direction, the first row and the second row being offset along a second direction running transversely with respect to the first direction; a first one of the test structures electrically connected to a first one of the connection contacts of the first row and a second one of the test structures electrically connected to a first one of the connection contacts of the second row; a third test structure electrically connected to the first one of the connection contacts of the first row; a second line electrically connected to the first one of the connection contacts of the first row, the first one of the test structures and the third one of the test structures and extending between one of the connection contacts of the first row and one of the connection contacts of the second row, the second line having sections running in the first direction and sections running in the second direction, the sections running in the second direction in each case arranged between one of the connection contacts of the first row and one facing the one of the connection contacts of the connection contacts of the second row.
