  • Scattering bar OPC application method for mask ESD prevention
    Patent number: 7614030
    Abstract: A method for reducing ESD on scattering bars in forming a mask containing a target pattern is provided. In one embodiment, the target pattern comprising features to be imaged onto a substrate is obtained. The mask is modified to include at least one scattering bar, the at least one scattering bar being placed adjacent to edges of the features to be imaged. Thereafter, the scattering bar is truncated into one or more scattering bar segments by determining an optimized length for each of the one or more scattering bar segments, wherein ESD on the one or more scattering bar segments is substantially reduced.

  • Cellulose fibers treated with acidic odor control agents
    Patent number: 6852904
    Abstract: An odor control system is formed by treating cellulose fibers with a partially neutralized carboxylic acid odor control agent. The odor control system absorbs odor and inhibits formation of various odor-producing bacteria. The odor control system is useful in the absorbent cores of a wide variety of personal care and medical absorbent garments.
