Yield Optimizer™ Software is a powerful tool that analyzes the relationships between in-process metrology measurements and end-of-line yield and electrical test results. It then will recommend changes to the in-process metrology targets to optimize the average end-of-line yield. Despite the highly complex algorithms employed to produce such tight predictive models, the Yield Optimizer is easy to train and requires minimal engineering effort to install and set up. Customers have achieved increases in product yield up to 8% after making just a few of the metrology target adjustments recommended by the Yield Optimizer.
