Thin Solid Films is an international journal which serves scientists and engineers working in the fields of thin-film synthesis, characterization, and applications. The field of thin films, which can be defined as the confluence of materials science, surface science, and applied physics, has become an identifiable unified discipline of. Aluminum alloys have virtually replaced aluminum thin films for interconnections in very large‐scale integration because of their improved reliability. Mechanical stress is a problem of growing importance in these interconnections. Stress as a function of temperature was measured for thin aluminum films on an oxidized silicon substrate and several aluminum alloys and layered films consisting. Nov 01, 2001 · The film stress σ can then be related to the deflection of the substrate at a distance r from the center of the substrate, by using the modified Stoney's formula,: 1 σ= E s 1−ν s t s 2 3r 2 δ t f where σ is the stress in the thin film, δ is the net deflection before and after deposition of thin film on the glass substrate, and r is.

Mechanical behavior problems in microelectronics ~ 1983 Craig Barrett, Intel David Barnett, Stanford Bill Nix, Stanford Consulting about mechanical reliability in metal interconnects – metal cracking Created need to understand stresses and mechanical properties of thin films –. Thin film metallizations are one of the most important interconnects in large-scale integrated circuits. They are covered by substrates and passivation films. Large hydrostatic mean tension develops due to the constraint and thermal mismatch, and voiding is identified as the failure mechanism.

The authors conducted a physico-chemical analysis of tensile sequential-nitrogen-plasma-treated silicon nitride films, which function as stressor liners in complementary metal oxide semiconductor CMOS technologies. These films are made of stacked nanometer-thick, plasma-enhanced, chemical vapor-deposited layers which were individually treated with N 2-plasma, to increase stress.

Journal description. The MRS Online Proceedings Library Archive includes more than 100,000 peer-reviewed papers online—proceedings published from Volume 1 through the 2015 MRS Spring Meeting. In order to advance flexible electronic technologies it is important to study the electrical properties of thin metal films on polymer substrates under mechanical load. At the same time, the observation of film deformation and fracture as well as the stresses that are present in the films during straining are also crucial to investigate. This work examines the mechanical performance of thin film coatings from Photosensitive-benzocyclobutene Photo-BCB formulations Cyclotene 2 4024, 4026 and 7200, on various substrate surfaces such as Al, Cu, Si, and SiN. The adhesion promoter used was designated AP-3000 and was based on vinyltriacetoxysilane VTAS, which had been properly hydrolyzed and advanced.

The mechanical properties of thin-film, low-pressure chemical vapor deposited silicon nitride were measured in uniaxial tension and by a bulge test method suitable for wafer-level testing. This research compares the two approaches and presents additional data on silicon nitride. The common property from the two test methods is the Young's modulus. Tensile tests performed at the Johns Hopkins.

Jul 15, 2001 · Thermal-stress-induced dislocation motion in a Cu film on an amorphous SiN x a-SiN x passivated Si substrate was investigated by in situ transmission electron microscopy TEM.Plan-view, in situ TEM experiments revealed a relatively constant dislocation density of 3.4×10 9 –5.9×10 9 cm −2 throughout thermal cycling. However, dislocation motion was strongly temperature dependent. Journal of Vacuum Science and Technology A is an interdisciplinary journal focused on interfaces and surfaces of materials, thin films, materials, interfaces, surfaces, and plasmas, devoted to publishing reports of original research, letters, and review articles. High precision force displacement indenting instruments are now widely used for the determination of the mechanical properties of materials. However, for thin films attached to a substrate, the. Essentially, if Young's modulus of a thin film is known, those methods can be used to determine Poisson's ratio of the thin film [10, 11]. Ziebart et al [12] reported a method to extract Young's.

The mechanical properties of ultrananocrystalline diamond UNCD thin films were measured using microcantilever deflection and membrane deflection techniques. Bending tests on several free-standing UNCD cantilevers, 0.5 μm thick, 20 μm wide and 80 μm long, yielded elastic modulus values of 916–959 GPa. The tests showed good reproducibility by repeated testing on the same cantilever and by. In order to model and design micromechanical sensors and actuators, it is of crucial importance that thin film mechanical parameters, such as the Young's modulus and the residual stress, are known.

Not logged in Not affiliated We measured the mechanical properties of dense and porous polymeric films, the modified polyarylethers, which have a low dielectric constant varying from 2.7 to 1.8, by combining three different methods; membrane bulge test, nanoindentation, and single-substrate bending beam method. The elastic modulus and initial stress measured from these three methods are in good agreement.

The mechanical properties of plain polydimethylsiloxane PDMS and its nanocomposites have been exploited for various theranostic biomedical applications. Although several research groups have investigated the effects of preparation conditions—especially curing temperature and time—on bulk mechanical properties of plain PDMS, there are no reported similar studies for its nanocomposites.. 15 hours ago · The most simple and traditional PENG structure is composed of bulk or a thin film base. Thin-film PVDF has advantages in flexibility and electrical output compared to bulk PVDF. Accordingly, various thin-film PVDF-based PENGs have been reported [33,34,35,36,37,38,39,40,41,42,43]. During hot‐pressing of α‐Si3N4 powders, the equiaxed α micro‐structure gradually transforms into a β structure characterized by needle‐shaped prismatic grains which are closely entangled and linked t.
