This paper summarizes a study that compares three different options for intrabay layouts and provides conclusions based on results from static and dynamic analysis. The three options were evaluated based on the impact each one of them has on total distance traveled by the lots, average delivery and transport times, vehicle counts and equipment set.","PeriodicalId":356225,"journal":{"name":"2001 IEEE International Symposium on Semiconductor Manufacturing.

This paper describes the relationship between line width uniformity and the illumination system of an exposure tool. Variation in the local value of partial coherence a is the cause of the optical proximity effect (OPE) variation across the image field of an exposure tool. By quantifying partial coherence /spl sigma/ and decreasing a variation, OPE variation within the image field was improved from 21.2 nm to 8.8 nm. We reduced OPE variation among tools by setting up these tools with agreeing a values. This paper also discusses the effect of illumination source uniformity on line width. Nonuniformity of an illumination source induces a line width difference between pair lines. We improved the treatment for these problems by adjusting the illumination source uniformity.","PeriodicalId":356225,"journal":{"name":"2001 IEEE International Symposium on Semiconductor Manufacturing.

Surface defects such as the surface native oxide or any other contamination may result in a poor adhesion of Ti/TiN, for example, and hence the poor salicide formation. HF treatment with IPA dry is a widely used methodology for surface defect removal, and results in a clean surface which is water spot free and has less chemical oxide. However, a cluster type defect is an accompaniment of this treatment in the salicide process. The aim of this work is to provide an optimized cleaning procedure at pre-metal clean for mass production.","PeriodicalId":356225,"journal":{"name":"2001 IEEE International Symposium on Semiconductor Manufacturing.

TiF/sub x/ formation by F atoms transported from the FSG film to the Ti/SiO/sub 2/ interface during the metallization process induced the delamination. Correlation between the Al-wiring delamination and F concentration at Ti/SiO/sub 2/ was demonstrated by a 3-D mapping of F concentrations at Ti/SiO/sub 2/ with various thickness of SiO/sub 2/ film and F content in the FSG film. Some treatments of the FSG/SiO/sub 2/ interlayer to reduce F accumulation at Ti/SiO/sub 2/ were also examined. It was revealed that more than 4500-/spl Aring/ thickness and strain relaxation of the compressive SiO/sub 2/ film were effective for F reduction at Ti/SiO/sub 2/. On the other hand, F concentration at Ti/SiO/sub 2/ was independent of F content in the FSG film in the range of 2-5 %. F content in FSG film should be kept as much as possible, that is, 4-5 % not to increase the capacitance between adjacent metal lines. The Al-wiring delamination was prevented by introducing these parameters of the FSG/SiO/sub 2/ interlayer into the fabrication line.","PeriodicalId":356225,"journal":{"name":"2001 IEEE International Symposium on Semiconductor Manufacturing.
