A new method to determine contamination limited yield

A method to determine the sensitivity of any process to particle contaminants is proposed. Particles of known sizes are seeded at various known locations on the product at known steps. The resulting defects are then measured directly. This is illustrated by a detailed example. The advantages of this seeding method are as follows: (1) the entire experiment can be done quickly; (2) the experiment can be easily replicated; (3) large sample sizes are not needed; (4) and the time spent for inspection and measurement of defects is much less than in any of the previous methods.<
