Sinopsis

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.

Excerpt from A Product Design Problem in Semiconductor Manufacturing

We consider the product design problem of allocating the chip sites on a semiconductor wafer to various types of chips. The manufacturing facility sells chips to its customers in sets (a specified number of several different types of chips), and the objective of the facility is to maximize the average production rate of sets. Variability in the wafer fabrication process, in particular random yield, poses a major obstacle in producing sets in a reliable fashion. A stochastic analysis is employed to develop an effective wafer design, and to measure the improvement in performance of the multi-type wafer over the traditional single-type wafer. The analysis reveals that multi-type wafers regularize the production flow of non-defective chips of each type and cause these flows to be positively correlated, both of which help to improve performance. A numerical example is provided that illustrates the analysis and demonstrates the design's effectiveness.
