Abstract
The Proximity Effect which results from electron scattering can be corrected in a number of ways. The most rigorous methods use computed changes to the pattern data base and are very costly to perform on very large circuit patterns. Alternatives are presented which are more practical to implement. They are: 1) CAD corrections to the data base, 2) layout and design rules, 3) GHOSTING, 4) system set-up, 5) tri-level resist, and 6) optimum use of the resist contrast behavior.
