  • Semiconductor die having a protective periphery region and method for forming
    Publication number: 20070087067
    Abstract: A die (10) for an integrated circuit comprising an active area (22) is provided. The die (10) may further comprise a first ring (12) in a peripheral region of the die (10) at least partially surrounding the active area (22), wherein the first ring (12) may comprise a plurality of polygon shaped cells (32, 36). The die (10) may further comprise a second ring (14) surrounding the first ring (12), wherein the second ring (14) may comprise a plurality of polygon shaped cells (32, 36).

  • Method for polishing a substrate
    Patent number: 5433650
    Abstract: A semiconductor substrate (48) and a block of optical quartz (50) are simultaneously polished. An interferometer (22), in conjunction with a data processing system (16), are then used to monitor the thickness and the polishing rate of the optical quartz block. This allows the endpoint of the polishing process to be automatically and reproducibly detected, and it also allows the polishing rate of the semiconductor substrate (48) to be automatically adjusted during the polishing process.
