Data mining methodology, on the other hand, is a hypothesis discovery process that is free from this constraint. yieldHUB combines semiconductor expertise with the latest cloud technologies. On the other hand, local disturbances affect only parts of the wafer and the affected area dimensions can be compared with IC features like contacts, transistors etc. A solution that enables you to improve yields and profits as well as to drive innovation. However, the scope of these analyses is restricted by the difficulty involved in applying the regression tree analysis to a small number of samples with many attributes. Scan diagnosis leverages existing design-for-test structures in the design and is based on automatic test pattern generation (ATPG) technology. yieldHUB helps make communication and collaboration seamless. A number of models for the prediction of yield of a semiconductor device due to random manufacturing defects have been proposed over the years. The path forward involves a shift in mind-sets as well as deployment of advanced-analytics solutions. Scan diagnosis helps identify the location and classification of a defect based on the design description, test patterns used to detect the failure, and data from failing pins/cycles as shown in Figure 1. Semiconductor yield may be defined as the fraction of total input transformed into shippable output (Cunningham, Spanos, & Voros, 1995).
