...David W. Niles; Ronald W. Kee Designing circuit edits at the contact level offers tremendous advantages in reliability and yield success over similar edits designed in the metal stack. To that end, a full-thickness backside circuit edit strategy has been developed that eliminates part thinning...

..., direct printed circuit board attachment (wafer-level, chip-scale packaging) is a recent trend to reduce packaging costs and presently appears to be the use for front-side ICs as flip-chips. These can be edited through the backside, but they are sometimes so small that handling them for back-side edit...

.... Naturally, if the device is no longer intact after this step, no amount of circuit editing can revive it into a functional device. Whether it s backside or frontside editing, begin by decapping the package. For backside editing, the next step is grinding and polishing of the device. For frontside editing...
