Abstract: A method includes receiving a first set of parameters associated with a particular die. A health metric for a particular die is determined using a multivariate analysis of the first set of parameters. The health metric incorporates at least one performance metric. At least one of a market segment designator or a testing plan associated with the particular die is determined based on the health metric.

Abstract: In one embodiment, a first dielectric layer (32) that overlies a fuse (16) and a bonding pad (30) is etched with a first etch process. This first etch process exposes a portion (40) of a second dielectric layer (20) that underlies the first dielectric layer (32) and overlies the fuse (16). In addition, the first etch process also forms a bond pad opening (38) that exposes a portion (42) of an anti-reflective layer (28) that forms a portion of the bonding pad (30). A second etch process is then used to etch the exposed portion (42) of the anti-reflective layer (28) and the exposed portion (40) of the second dielectric layer (20) at substantially the same rate to form a fuse window (45) overlying the fuse (16). The second etch process prevents over etching of the second dielectric layer (20), and thus exposure of the underlying fuse (16).
