This paper will provide a high level overview of the future for in-line high volume manufacturing (HVM) metrology for the semiconductor industry, concentrating on logic applications. First, we will take a broad view of the needs of patterned defect, critical dimensional (CD/3D), overlay and films metrology, and present the extensive list of applications for which metrology solutions are needed. Commonalities and differences among the various applications will be shown. We will then report on the gating technical limits of the most important of these metrology solutions to address the metrology challenges of future nodes, highlighting key metrology technology gaps requiring industry attention and investment
