Excerpt from A Product Design Problem in Semiconductor Manufacturing
Because of the complexity of the technology and the fast-changing nature of the semi conductor industry, the yield of non-defective chips in wafer fabrication can be low and very erratic. Average yield rates can vary from several percent up to eighty or ninety percent depending upon the maturity and complexity of the product. Chips are made on wafers, and wafers are produced in lots, where the lot size is typically between five and fifty. In this paper, three different possibilities for producing defective chips will be explicitly considered: an entire lot can be defective, an entire wafer in a non-defective lot can be defective, and finally an individual chip on a non-defective wafer can be defective.

Paperback. Zustand: New. Print on Demand. This book tackles the intricate relationship between design and variability in semiconductor manufacturing, proposing an effective yet simple design for multi-type semiconductor wafers that outperforms traditional designs with reduced variability and improved efficiency. The author employs a nuanced understanding of stochastic analysis and mathematical programming to develop a design that enhances the flow of non-defective chips, leading to a surge in production. Through a numerical example, the book demonstrates the significant improvement in cumulative production when using the proposed multi-type wafer design, outperforming the single-type design by over 11%, and reaching up to 94% of the theoretical deterministic production rate. With its focus on practical solutions and accessible explanations, this book offers valuable insights to manufacturing professionals, engineers, and students seeking to optimize production processes in the face of variability. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
