Available in PDF, EPUB and Kindle. Book excerpt: A method is described for applying a known tensile stress to a thin-film structure without requiring any mechanical attachment to the film. The stress is developed by the interaction of an external magnetic field with an electric current through a suitably patterned specimen of the film to be evaluated. An apparatus for producing the required magnetic fields and electric currents is described, and procedures are given for preparing suitable test specimens using conventional electronic device fabrication technology. Results showing the use of this technique for measuring the adhesion of evaporated copper on thermally oxidized silicon are presented. The maximum stress which can be produced is limited by the available magnetic field, the fabrication of the test structure, and the heating effect of the current through this structure. These factors are discussed, and it is shown that useful stresses of at least 24 000 psi (165 600 kPa) are practical by the electromagnetic method.

Book excerpt: A detailed study of the scratch test was undertaken to determine its sensitivity, reproducibility, and soundness as a means of measuring the adhesion of aluminum films on fused quartz substrates. The complete-removal failure criterion was found to be quite subjective and often ambiguous, finally leading to the threshold adhesion failure (TAF) concept. Using the TAF approach, it was found that the scratch test is sensitive enough to discriminate between failure and nonfailure within 0.1 g of stylus loading at both low- and high-load levels. Also, the reproducibility of the mean TAF loads is excellent. In addition to the expected TAF load dependence on stylus tip radius of curvature and film thickness, it was also found that any one stylus has its own scribing characteristics which are reflected in the TAF load. The mean TAF loads are, therefore, relative measurements.

Book excerpt: Methods to evaluate the adhesion of thin evaporated films to their substrate were devised. One was to pull down and the other to twist off a rod whose bottom was cemented with epoxy to the film. The critical force or torque to strip off the film from the substrate was taken as a measure of the adhesion. It was important to maintain adequate temperature and humidity [16 °C (61 °F) and below 60 percent] during the cementing and measurement, to assure the high adhesion of the cement and the reproducibility of the result.

The articles in this book were previously published in three special issues of the Journal of Adhesion Science and Technology. Films and coatings are used for a variety of purposes and their adequate adhesion to the underlying substrates is of cardinal importance from practical consideration. In the last two decades there has been brisk activity in devising new ways to measure adhesion or ameliorating the existing techniques.
Download or read book Thin Film Adhesion Measurement Using Excimer Laser Ablation Test written by Wen-Chieh Lee and published by . This book was released on 1991 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An excimer laser incident on a metallic thin film is used to measure the adhesion between the film and the substrate. The initial optical absorption leads to electron excitation. After collisions and degradation of the excited electrons, the absorbed energy is transferred into various kinds of energy among which the major one is thermal. The superheated surface undergoes vapor explosion which serves as one source of shock wave to break the thin film. The evaporated particles may recoil back to the surface constructing another shock wave to break the film. In addition, a tensile stress may be formed by the large difference of thermal expansion between metallic thin film and polymeric substrate. All these effects cooperate to cause the cracking of the metallic thin film. This thesis provides the theoretical models to explain how the various mechanisms work on adhesion evaluation. Based on these understandings, the experimental data of laser ablation test is more suggestive and meaningful than the tape test which is sometimes ambiguous due to undiscerned effects. The experimental results show that laser ablation is sensitive to small differences in adhesion. In addition, the laser ablation test has a broader range of measurement as compared to that of tape test. One thing to be noticed is that laser ablation test is strongly affected by the thickness of the film."--Abstract.
Download or read book Interaction of Copper with a Vapor Deposited Polyimide Film written by R. G. Mack and published by . This book was released on 1990 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of copper with a vapor deposited film of PMDA-ODA polyimide was studied using x-ray photoelectron spectroscopy (XPS) and scanning tunnelling microscopy (STM). Copper was evaporated onto the polyimide surface to total thickness estimated to be about five atomic layers. The copper initially interacts with the planar imide ring - the nitrogen XPS signal is preferentially attenuated, some copper is oxidized, and the carbonyl XPS intensities are altered. We find no evidence for chemical interaction with the ODA part of the polyimide. Heating the copper covered surface leads to redistribution of copper, probably below the surface as reported in earlier studies. STM images of the heated surfaces show that substantial surface roughening has occurred. Keywords: Polyimide, Polymer films, Polymer-metal interface, Adhesion, X-ray photoelectron spectroscopy, Scanning tunneling microscopy.
