Popis: Semiconductor device manufacturing demands rapid ramp of yield together with feature size reduction, especially for logic and ASIC because of their short-lives and small volume production characteristics. As a technological breakthrough for rapid yield ramp of such devices, we have endeavored to integrate CAD technology with SEM for printed pattern observation, and have developed Grade Scope, an evaluation technology, by combining the wafer proces and upstream design process.
