Yield Modeling and Analysis . Prof. Robert C. Leachman . IEOR 130, Methods of Manufacturing Improvement . Spring, 2017 . 1. Introduction . Yield losses from wafer fabrication take two forms: line yield and die yield. Line yield losses result from physical damage of the wafers due to mishandling, or by mis-

Yield and Yield Management 3-2 INTEGRATED CIRCUITENGINEERING CORPORATION Random defects can be traced back to the tools, the people, the processes, the process chemicals and gases, or the cleanroom itself. Over the years, cleanroom technology and the purification of pr ocess materials has been improved so dramatically that the majority

manufacturing divided by the number of assemblies that start the manufacturing process. One way to characterize the quality of a process is with yielded cost. Process yielded cost, CYtotal, characterizes the quality of the entire process under consideration and is defined as the total cost invested per assembly divided by the total process yield.

Voros, 1995). Hu (2009) points out that yield analysis usually has two purposes: to determine the root cause of yield loss and to build accurate models to predict yield. From a manufacturing viewpoint, it is also extremely important to predict yield impact based on in-line inspections (Nurani, Strojwas, Maly, Ouyang, Shindo, Akella, et al. (1998).

limited yield loss is projected to be the dominant source of yield loss in current and future technology generations [3]. Decision at the IC manufacturing site of which parts are not working and should be discarded is an important one. Though this is more a discussion of testing and testability,
