Patent ID: 7897485

Claim:
A method for processing a semiconductor wafer, comprising: forming a number of electronic devices on a first side of the semiconductor wafer; removing portions of the first side of the semiconductor wafer to form a first number of trench rows to a first width wherein each of the first number of trench rows includes a continuous bottom surface and a second number of trench rows to a second width wherein each of the second number of trench rows includes a continuous bottom surface; removing portions of the first side of the semiconductor wafer to form a first number of trench columns to a third width wherein each of the first number of trench columns includes a continuous bottom surface and a second number of trench columns to a fourth width wherein each of the second number of trench columns includes a continuous bottom surface; forming a number of test circuits on the semiconductor wafer; and cutting a second side of the semiconductor wafer in rows and columns aligned with the number of trenches such that the semiconductor wafer singulates into a number of dice corresponding to the number of electronic devices wherein at least one of the first, second, third, and fourth widths is a different width than at least one of the other widths.
