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-processing of the wafer (e.g., skipping or duplicating a process step, wrong recipe, ................
