Integrated circuit yield statistics

Abstract
The random failure statistics for the yield of mass-produced semiconductor integrated circuits are derived by considering defect and fault formation during the manufacturing process. This approach allows the development of a yield theory that includes many models that have been used previously and also results in a practical control model for integrated circuit manufacturing. Some simpler formulations of yield theory that have been described in the literature are compared to the model. Application of the model to yield management are discussed and examples given.
