“This is the die of a Realtek ALC655 AC’97 audio CODEC. This came off a P4 mainboard that burned out. Sulfuric acid was used to liberate this die, however, the black coatings at the top left and bottom right sides of the die are simply super-glue and the result of a sloppy mounting job by myself. Still no artifacts and a lot of metal on the surface. Some interesting features can be seen in the three successive 100x images with varying depth.”
