Aerial Image Microscopes for the Inspection of Defects in EUV Masks (open access)

Aerial Image Microscopes for the Inspection of Defects in EUV Masks

The high volume inspection equipment currently available to support development of EUV blanks is non-actinic. The same is anticipated for patterned EUV mask inspection. Once potential defects are identified and located by such non-actinic inspection techniques, it is essential to have instrumentation to perform detailed characterization, and if repairs are performed, re-evaluation. The ultimate metric for the acceptance or rejection of a mask due to a defect, is the wafer level impact. Thus measuring the aerial image for the site under question is required. An EUV Aerial Image Microscope (''AIM'') similar to the current AIM tools for 248nm and 193nm exposure wavelength is the natural solution for this task. Due to the complicated manufacturing process of EUV blanks, AIM measurements might also be beneficial to accurately assessing the severity of a blank defect. This is an additional application for an EUV AIM as compared to today's use In recognition of the critical role of an EUV AIM for the successful implementation of EUV blank and mask supply, International SEMATECH initiated this design study with the purpose to define the technical requirements for accurately simulating EUV scanner performance, demonstrating the feasibility to meet these requirements and to explore various technical approaches …

Air Quality: Multi-Pollutant Legislation

One approach being proposed to more cost-effectively achieve national air quality goals is a "multi-pollutant" strategy -- a framework based on a consistent set of emissions caps, implemented through emissions trading. This report discusses this strategy and related legislation.

Budget Enforcement Procedures: Senate Pay-As-You-Go (PAYGO) Rule

The Senate “pay-as-you-go,” or PAYGO, rule generally requires that any legislation increasing direct spending or reducing revenues be offset. A motion to waive the rule requires an affirmative vote of three-fifths of the membership (i.e., 60 Senators if no seats are vacant). Beginning in 1993, six points of order under the PAYGO rule have been raised against an entire bill or an amendment. Of these six points of order, four were sustained and two fell upon the adoption of a waiver motion.

Combating Terrorism: Actions Needed to Improve Force Protection for DOD Deployments through Domestic Seaports (open access)

Combating Terrorism: Actions Needed to Improve Force Protection for DOD Deployments through Domestic Seaports

A letter report issued by the General Accounting Office with an abstract that begins "The October 12, 2000, attack against the Navy destroyer U.S.S. Cole in the port of Aden illustrated the danger of unconventional threats to U.S. ships in seaports. The September 11, 2001, attacks further heightened the need for a significant change in conventional antiterrorist thinking, particularly regarding threats to the U.S. homeland. The new security paradigm assumes that all U.S. forces, be they abroad or at home, are vulnerable to attack, and that even those infrastructures traditionally considered of little interest to terrorists, such as commercial seaports in the continental United States, are now commonly recognized as highly vulnerable to potential terrorist attack. Of the more than 300 seaports in the United States, the Departments of Defense (DOD) and Transportation have designated 17 as "strategic," because in the event of a large-scale military deployment, DOD would need to transport more than 95 percent of all equipment and supplies needed for military operations by sea. If the strategic ports were attacked, not only could massive civilian casualties be sustained, but DOD could also lose precious cargo and time and be forced to rely heavily on its overburdened airlift …

Connectivity in Random Grain Boundary Networks (open access)

Connectivity in Random Grain Boundary Networks

Mechanical properties of FCC metals and alloys can be improved by exercising control over the population of grain boundary types in the microstructure. The existing studies also suggest that such properties tend to have percolative mechanisms that depend on the topology of the grain boundary network. With the emergence of SEM-based automated electron backscatter diffraction (EBSD), statistically significant datasets of interface crystallography can be analyzed in a routine manner, giving new insight into the topology and percolative properties of grain boundary networks. In this work, we review advanced analysis techniques for EBSD datasets to quantify microstructures in terms of grain boundary character and triple junction distributions, as well as detailed percolation-theory based cluster analysis.

ELECTRONS IN NONPOLAR LIQUIDS. (open access)

ELECTRONS IN NONPOLAR LIQUIDS.

Excess electrons can be introduced into liquids by absorption of high energy radiation, by photoionization, or by photoinjection from metal surfaces. The electron's chemical and physical properties can then be measured, but this requires that the electrons remain free. That is, the liquid must be sufficiently free of electron attaching impurities for these studies. The drift mobility as well as other transport properties of the electron are discussed here as well as electron reactions, free-ion yields and energy levels, Ionization processes typically produce electrons with excess kinetic energy. In liquids during thermalization, where this excess energy is lost to bath molecules, the electrons travel some distance from their geminate positive ions. In general the electrons at this point are still within the coulombic field of their geminate ions and a large fraction of the electrons recombine. However, some electrons escape recombination and the yield that escapes to become free electrons and ions is termed G{sub fi}. Reported values of G{sub fi} for molecular liquids range from 0.05 to 1.1 per 100 eV of energy absorbed. The reasons for this 20-fold range of yields are discussed here.

Evaluation of Corrosion Failure in Tractor-Trailer Brake System (open access)

Evaluation of Corrosion Failure in Tractor-Trailer Brake System

As reported to ORNL, concomitant with the introduction of different deicing and anti-icing compounds, there was an increase in the brake failure rate of tractor-trailer trucks. A forensic evaluation of a failed brake system was performed. Optical and scanning electron microscopic evaluation showed corrosion to be mostly confined to the brake table/lining interface. The corrosion is non-uniform as is to be expected for plain carbon steel in chloride environments. This initial analysis found no evidence for the chlorides of calcium and magnesium, which are the newly introduced deicing and antiicing compounds and are less soluble in water than the identified chlorides of sodium and potassium, in the scale. The result could be as a result of non-exposure of the examined brake table to calcium and magnesium chloride. The mechanisms for the increased failure rate are postulated as being an increased rate of corrosion due to positive shifts in the corrosion potential, and an increased amount of corrosion due to an increased ''time of wetness'' that results from the presence of hygroscopic salts. Laboratory scale evaluation of the corrosion of plain carbon steel in simulated deicing and anti-icing solutions need to be performed to determine corrosion rates and morphological development of …

Immigration Benefits: Eighth Report Required by the Haitian Refugee Immigration Fairness Act of 1998 (open access)

Immigration Benefits: Eighth Report Required by the Haitian Refugee Immigration Fairness Act of 1998

Correspondence issued by the General Accounting Office with an abstract that begins "The Haitian Refugee Immigration Fairness Act (HRIFA) of 1998 authorized certain Haitian nationals and their dependents to apply to adjust their status to legal permanent residence. Section 902(k) of the act requires the Comptroller General to report every six months on the number of Haitian nationals who have applied and been approved to adjust their status to legal permanent residence. The reports are to contain a breakdown of the numbers who applied and the number who were approved as asylum applicants, parolees, children without parents, orphaned children, or abandoned children; or as the eligible dependents of these applicants, including spouses, children, and unmarried sons or daughters. As of September 30, 2002, the Immigration and Naturalization Service had received a total of 36,774 HRIFA applications and had approved 8,410 of these applications. The Executive Office for Immigration Review had 339 applications filed and had approved 117 of them."
