Abstract:
In this work, we carried out an overlay-aware variation study on Flip FET (FFET) considering the impact on RC parasitics induced by the lithography misalignment in backside processes, and benchmarked it with CFET in terms of the power-performance (PP) and variation sources. The iso-leakage frequency degrades up to 2.20% with layout misalignment of 4 nm. It's found that the Drain Merge resistance degrades significantly with misalignment increasing and is identified as the major variation source. Through careful DTCO with design rule optimization, the variation can be greatly suppressed, while the resistance fluctuation of the DM also drops substantially. Monte Carlo random experiments were also conducted, validating the variation reduction. Comparing with the CFET featuring self-aligned gate and much less overlay induced misalignment, fortunately, FFET's PP is still better except when misalignment reaches 8 nm, which is out of spec and nearly impossible. Considering the variabilities induced by the high aspect ratio processes, CFET still faces big challenges compared with FFET.Keywords:

Firstly,according to variation contents,the paper divides variation into operating range variation,construction condition variation,design variation,construction variation and technique standards variation. Contraposing to different content variation,the paper puts forward dissimilar control methods. According to the property of project variation,the paper divides variation into fatal variation,important variation and general variation,and points out that we can control variation effectively by establishing dissimilar authority of project variation examination and approval. Finally,according to the urgency of variation,the paper divides variation into variation under urgent circumstance and variation under not urgent circumstance,and puts forward that we can control these variation by different procedure.

This is the third of a three volume report prepared to provide highway engineers a ready reference on overlay design procedures. It contains a discussion of the evaluation procedure needed for determining if an overlay is required, the basic requirements of an overlay design procedure, reflection crack concerns, preoverlay repair recommendations, selection of the proper overlay type, and timing of overlay construction.

As a consequence of the shrinking sizes of the integrated circuit structures, the overlay budget shrinks as well. Overlay is traditionally measured with relatively large test structures which are located in the scribe line of the exposure field, in the four corners. Although the performance of the overlay metrology tools has improved significantly over time it is questionable if this traditional method of overlay control will be sufficient for future technology nodes. For advanced lithography techniques like double exposure or double patterning, in-die overlay is critical and it is important to know how much of the total overlay budget is consumed by in-die components. We reported earlier that small overlay targets were included directly inside die areas and good performance was achieved. This new methodology enables a wide range of investigations. This provides insight into processes which were less important in the past or not accessible for metrology. The present work provides actual data from productive designs, instead of estimates, illustrating the differences between the scribe line and in-die registration and overlay. The influence of the pellicle on pattern placement on mask and wafer overlay is studied. Furthermore the registration overlay error of the reticles is correlated to wafer overlay residuals. The influence of scanner-induced distortions (tool to tool differences) on in-die overlay is shown. Finally, the individual contributors to in-die-overlay are discussed in the context of other overlay contributors. It is proposed to use in-die overlay and registration results to derive guidelines for future overlay and registration specifications. It will be shown that new overlay correction schemes which take advantage of the additional in-die overlay information need to be considered for production.

The objectives of this study were to: (1) determine the cost effectiveness of thin hot mix asphalt (HMA) overlays as a maintenance technique; (2) determine under what conditions a thin overlay would be suitable; (3) determine the timing of constructing a thin overlay to maximize its benefits; and (4) develop a prototype aggregate source information system to correlate aggregate source quality to pavement performance. Performance data for thin overlays constructed by the Ohio Department of Transportation (ODOT) since 1990 were collected to study the cost-effectiveness of thin overlay.

The technical and economic optimization of asphalt overlay thickness on old concrete pavements was the target of a test track constructed in Lower Austria in the years 1988 to 1990. A conventional type of overlay was compared with thinner overlays using various stress absorbing interlayers. After a period of four years tentative conclusions about the behaviour and performance of the different solutions can be drawn. The best results so far show a conventional 120 mm overlay and the use of geogrids. The first will need a longer time of observation. Regarding costs, overlays with the use of stress absorbing interlayers vary between +/- 10% from those for a conventional overlay. (A) For the covering abstract see IRRD 857794.

Abstract Although overlaying code segments is a very old technique, there is very little literature 68 on what the ground rules are, what the options are and how to select an overlay structure. As a result, the facilities provided by most linkage editors are much poorer than they need be. In this paper we define the problem, give an algorithm for obtaining ‘minimal’ overlay structures and describe the surrounding commands and environment that are necessary to turn this algorithm into a practical tool.
