Boron carbon nitride coatings have been synthesized by the pulsed laser deposition method. Vickers micro-hardness and adhesion of the coatings were studied. A new model was applied to determine the hardness of the coatings which were too thin to be directly measured by the Vickers micro-hardness test. An intermediate layer of silicon was used to enhance the adhesion of the coatings on stainless steel, glass, and quartz substrates.

AbstractWe have investigated the growth of carbon nitride (CNx) coatings on various substrates using laser assisted methods such as pulsed laser deposition (PLD) and laser chemical vapor deposition (LCVD). It has been shown that the both techniques produce good quality thin films of CNx. In PLD, a laser beam (λ= 248 nm) has been used to ablate the pyrolytic graphite target in nitrogen atmosphere, where as CO2 laser was used to irradiate carbon-nitrogen containing mixtures such as C2H2/N20/NH3 in LCVD method. A comparative analysis will be presented in terms of structural properties of CNx films prepared by both techniques.

Abstract The present work investigated the use of the Vickers micro-hardness test method to determine the resistance of individual die to cracking. The results are used as an indicator of resistance to failure under the thermal and mechanical stresses of packaging and subsequent thermal cycling. Indentation measurements on die back surfaces are used to determine how changes in wafer backside processing conditions affect cracks that form around impressions produced at different loads. Test methodology and results obtained at different processing conditions are discussed.
