摘要

As Integrated Circuit (IC) industry changes rapidly, introducing smaller design rules with shorter life cycles, a new product will be introduced to mass production fabs in a short period of time. In order to rapidly ramp up a new process, in-line defect review and classification is required, since it can provide faster root cause analysis, thus improved yield and fab productivity. Traditionally, it takes approximately one month to optimize an in-line ADR/ADC (Automatic Defect Review/Classification) recipe for a new product. However, this is not sufficient for rapid industrial changes. This study, introduces a time saving idea by the use of a modular recipe concept. This concept enables review of similar layers across multiple products – without the need to re-tune the ADR/ADC recipe elements. Using this method, PSC Fab12A could implement a new in-line ADR/ADC recipe for 0.13 μm products, based on 0.15 μm defect database, within two hours.
