  Every process has a Yield. Yield in the context of this paper is defined as process-inherent output (before any quality control, auditing or testing) that meets specifications or customer expectations. To keep the terminology simpler, this paper deals only with manufacturing despite the fact that the results are universally applicable.

  cumulative yield of the process is only 83.9. This decrease in overall yield will become more pronounced as the number of process steps increases. There are various factors that a ect the overall fab yield 1.Number of process steps - for a 50 step process to get 75% yield, the individual steps must each have a yield greater than 99.4%.

  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-processing of the wafer (e.g., skipping or duplicating a process step, wrong recipe, equipment out of control, etc.). Mis-processing is detected either by in-line inspections
