  • Patent number: 8343842
    Abstract: A semiconductor process and apparatus to provide a way to reduce plasma-induced damage by applying a patterned layer of photoresist which includes resist openings formed over the active circuit areas as well as additional resist openings formed over inactive areas in order to maintain the threshold coverage level to control the amount of resist coverage over a semiconductor structure so that the total amount of resist coverage is at or below a threshold coverage level. Where additional resist openings are required in order to maintain the threshold coverage level, these openings may be used to create additional charge dissipation structures for use in manufacturing the final structure.
    Type: Grant
    Filed: March 31, 2011
    Date of Patent: January 1, 2013
    Assignee: Freescale Semiconductor, Inc.
    Inventors: David M. Schraub, Terry A. Breeden, James D. Legg, Mehul D. Shroff, Ruiqi Tian
  • Publication number: 20110179394
    Abstract: A semiconductor process and apparatus to provide a way to reduce plasma-induced damage by applying a patterned layer of photoresist (114) which includes resist openings formed (117) over the active circuit areas (13, 14) as well as additional resist openings (119) formed over inactive areas (15) in order to maintain the threshold coverage level to control the amount of resist coverage over a semiconductor structure so that the total amount of resist coverage is at or below a threshold coverage level. Where additional resist openings (119) are required in order to maintain the threshold coverage level, these openings may be used to create additional charge dissipation structures (e.g., 152) for use in manufacturing the final structure.
