This page contains links to a number of online articles
on semiconductor yield which we found interesting.

This article is one of a series discussing cost-effective
experimental design when trying to improve production yield.
Of particular interest in this article is a discussion of
how truth tables similar to the type produced by Q-YIELD
should be interpreted. The article also discusses other
statistical measures. See also Part
II and Part
III which unfortunately aren't linked to from Part I.

This isn't a single paper, but a link to the web site of
the Y4 (Yield FOREcasting) project. You've heard of the
game SimCity - well this is SimFab! This project developed
a simulator which enables cost vs. yield trade-off analyses,
predicting, for example, the effect of yield disruptions
on learning rate and cost.

This is one of the best papers I've seen in the trade press
in this area. The authors view data analysis as a powerful
technique to be used in combination with statistical process
control and design of experiments. Although a working knowledge
of statistics is required to fully understand some of the
details, the worked examples give a good impression of the
techniques used and the results obtained. (Note that the
yield figures in this article were adjusted for commercial
International generally contains a column on yield management
in each issue, and has in the past contained several interesting
feature articles relating to semiconductor yield.
Unfortunately their website has been re-organized and now requires
registration for access, so we can no longer link you directly to
some of the better articles on their site. Try using their
search box to search
for "Yield Management" and look through the older archived
articles. Note that free subscriptions
to this magazine are available to qualified individuals.
