Advances in the reduction and compensation of film stress in high-reflectance multilayer coatings for extreme ultraviolet lithography applications (open access)

Advances in the reduction and compensation of film stress in high-reflectance multilayer coatings for extreme ultraviolet lithography applications

Due to the stringent surface figure requirements for the multilayer-coated optics in an extreme ultraviolet (EUV) projection lithography system, it is desirable to minimize deformation due to the multilayer film stress. However, the stress must be reduced or compensated without reducing EUV reflectivity, since the reflectivity has a strong impact on the throughput of a EUV lithography tool. In this work we identify and evaluate several leading techniques for stress reduction and compensation as applied to Mo/Si and Mo/Be multilayer films. The measured film stress for Mo/Si films with EUV reflectances near 67.4% at 13.4 nm is approximately - 420 MPa (compressive), while it is approximately +330 MPa (tensile) for Mo/Be films with EUV reflectances near 69.4% at 11.4 nm. Varying the Mo-to-Si ratio can be used to reduce the stress to near zero levels, but at a large loss in EUV reflectance (> 20%). The technique of varying the base pressure (impurity level) yielded a 10% decrease in stress with a 2% decrease in reflectance for our multilayers. Post-deposition annealing was performed and it was observed that while the cost in reflectance is relatively high (3.5%) to bring the stress to near zero levels (i.e., reduce by 1 00%), …

CAPTURING UNCERTAINTY IN UNSATURATED-ZONE FLOW USING DIFFERENT CONCEPTUAL MODELS OF FRACTURE-MATRIX INTERACTION (open access)

CAPTURING UNCERTAINTY IN UNSATURATED-ZONE FLOW USING DIFFERENT CONCEPTUAL MODELS OF FRACTURE-MATRIX INTERACTION

Preliminary calculations show that the two different conceptual models of fracture-matrix interaction presented here yield different results pertinent to the performance of the potential repository at Yucca Mountain. Namely, each model produces different ranges of flow in the fractures, where radionuclide transport is thought to be most important. This method of using different flow models to capture both conceptual model and parameter uncertainty ensures that flow fields used in TSPA calculations will be reasonably calibrated to the available data while still capturing this uncertainty. This method also allows for the use of three-dimensional flow fields for the TSPA-VA calculations.

A description of the expanded test problems in the TRAC-P standard test matrix (open access)

A description of the expanded test problems in the TRAC-P standard test matrix

This report describes the expanded set of test problems that were created to augment the existing Transient Reactor Analysis Code (TRAC)-P standard matrix of test problems. The expanded test problems were created to support the TRAC-P modernization effort. In most cases, these test problems were modified or expanded versions of problems in the TRAC Standard Test Matrix. A problem description is included for each problem added to the Standard Test Matrix. In this description, the details regarding modifications of the original test problem are included, as well as the observed problem results. This expanded test set will be used to verify that the predicted results for the modernized version of TRAC-M/f90 are null relative to the archival version of TRAC-P/MOD2 (Ver. 5.4.25), the latter being the base version on which work on the modernized code began. The problems described in this document increase the percentage of executable source coding that is activated when the Standard Test Matrix is run from 71% to 83.5%. A brief review of the characteristics of the portions of the source code that are not activated when running the expanded Standard Test Set also is provided. With a few exceptions, the author has concluded that the …

An implementation of the LHCb level 0 muon trigger using the 3D-Flow ASIC (open access)

An implementation of the LHCb level 0 muon trigger using the 3D-Flow ASIC

We have investigated the possibility of implementing the L0 trigger using 3D-Flow asics currently under development. Several nice features of the 3D-Flow technique lend themselves to the L0 muon trigger. Among these features are: (1) the ability to gather information (in the case of the muon detector, binary hit information from pads) from a relatively large volume of the detector in an organized way, routing quickly to one cpu all the necessary information to identify a muon and to calculate its {theta}{sub x}, {theta}{sub y}, x intercept at the position of {micro}1 stations and y intercept at the interaction region in less than 3.2 {micro}s; and (2) the ability to naturally buffer events so as to allow the requisite time for individual events to be calculated, respecting the limit that the average time per event must be <3.2 {micro}s. The LHCb Muon Detector components necessary for the LHCb L0 muon trigger are schematically shown in Fig. 1. The parameters of the LHCb Muon detector are given elsewhere in more detail. Briefly, the muon detector consists of a shield whose components include the EM and hadron calorimeters and four layers of steel representing a dE/dx of {approx} 6 GeV and 20 …
