Stochastic printing failures in extreme ultraviolet lithography

De Bisschop, Peter·2018·Journal of Micro/Nanopatterning, Materials, and Metrology

Abstract

Stochastic effects in lithography are known to be the cause of critical dimension (CD) variability, quantified, e.g., by linewidth roughness or local CD uniformity, but—when the CDs are small—they can also lead to printing failures, and hence have a significant impact on yield. We will focus on these printing failures and review three important topics in this relatively new field. First, we will look at how these failures can be detected and show how either CD-SEM, e-beam inspection, and optical defect inspection can play a useful role. Next, we consider the important question of how the stochastic failure probability (which we quantify by a metric we call “Not OK,” abbreviated NOK) depends on the lithography- and process-settings, a question that is of obvious importance when looking for conditions that will minimize the failure probability and hence maximize the yield. Finally, we will discuss to what extent we can fit experimentally observed failure probabilities, to empirical models. Such models can play a vital role in future OPC-verification flows, where screening full mask layouts for “stochastic hot spots” is expected to become a mandatory step.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Exposure defects can arise from mask particles or defects, resist and underlayer impurities, or local random stochastic defects that need proper characterization.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
