many products use pecvd coatings, but you might not know much about them. here’s a rundown of everything you ever wondered about pecvd coatings.
pecvd, plasma enhanced chemical vapor deposition, is used to deposit thin films from a gas state to a solid state on a substrate. experimental study from the x-ray diffraction spectra of silicon-oxide films deposited as a function of radio frequency (rf) power apparently indicates that rf power might be playing a stabilizing role and produces better deposition. the results show that the rf power results in smoother morphology, improved crystallinity, and lower sheet resistance value in the pecvd process. the pecvd processing allows deposition at lower temperatures, which is often critical in the manufacture of semiconductors. in this invited talk we will address two aspects of the problem, first to develop a model to study the mechanism of how the pecvd is effected by the rf power, and second to actually simulate the effect of rf power on pecvd. as the pecvd is a very important component of the plasma processing technology with many applications in the semiconductor technology and surface physics, the research proposed here has the prospect to revolutionize the plasma processing technology through the stabilizing role of the rf power. recent results obtained after the abstract submission will also be included.
pecvd films are found in nearly every device, serving as encapsulants, passivation layers, hard masks, and insulators.

plasma enhanced chemical vapor deposition technique plays a key role in the development of solar cells based on amorphous and microcrystalline silicon thin films. the deposition process depends strongly on physical and chemical interactions in the plasma. subsequently, the film properties are dependent on different parameters such as power and frequency, the substrate temperature, the gas pressure and composition, the magnitude and the pattern of the gas flow, the electrode geometry, etc. the aim of this chapter is to discuss all effects of these parameters in detail.
chemical vapor deposition (cvd) is a technique for the fabrication of thin films of polymeric materials, which has successfully overcome some of the issues faced by wet chemical fabrication and other deposition methods. there are many hybrid techniques, which arise from cvd and are constantly evolving in order to modify the properties of the fabricated thin films. amongst them, plasma enhanced chemical vapor deposition (pecvd) is a technique that can extend the applicability of the method for various precursors, reactive organic and inorganic materials as well as inert materials. organic/inorganic monomers, which are used as precursors in the pecvd technique, undergo disintegration and radical polymerization while exposed to a high-energy plasma stream, followed by thin film deposition. in this chapter, we have provided a summary of the history, various characteristics as well as the main applications of pecvd. by demonstrating the advantages and disadvantages of pecvd, we have provided a comparison of this technique with other techniques. pecvd, like any other techniques, still suffers from some restrictions, such as selection of appropriate monomers, or suitable inlet instrument. however, the remarkable properties of this technique and variety of possible applications make it an area of interest for researchers, and offers potential for many future developments.
chemical vapor deposition (cvd) with its plasma-enhanced variation (pecvd) is a mighty instrument in the toolbox of surface refinement to cover it with a layer with very even thickness. remarkable the lateral and vertical conformity which is second to none. originating from the evaporation of elements, this was soon applied to deposit compound layers by simultaneous evaporation of two or three elemental sources and today, cvd is rather applied for vaporous reactants, whereas the evaporation of solid sources has almost completely shifted to epitaxial processes with even lower deposition rates but growth which is adapted to the crystalline substrate. cvd means first breaking of chemical bonds which is followed by an atomic reorientation. as result, a new compound has been generated. breaking of bonds requires energy, i.e., heat. therefore, it was a giant step forward to use plasmas for this rate-limiting step. in most cases, the maximum temperature could be significantly reduced, and eventually, also organic compounds moved into the preparative focus. even molecules with saturated bonds (ch4) were subjected to plasmas—and the result was diamond! in this article, some of these strategies are portrayed. one issue is the variety of reaction paths which can happen in a low-pressure plasma. it can act as a source for deposition and etching which turn out to be two sides of the same medal. therefore, the view is directed to the reasons for this behavior. the advantages and disadvantages of three of the widest-spread types, namely microwave-driven plasmas and the two types of radio frequency-driven plasmas denoted capacitively-coupled plasmas (ccps) and inductively-coupled plasmas (icps) are described. the view is also directed towards the surface analytics of the deposited layers—a very delicate issue because carbon is the most prominent atom to form multiple bonds and branched polymers which causes multifold reaction paths in almost all cases. purification of a mixture of volatile compounds is not at all an easy task, but it is impossible for solids. therefore, the characterization of the film properties is often more orientated towards typical surface properties, e.g., hydrophobicity, or dielectric strength instead of chemical parameters, e.g., certain spectra which characterize the purity (infrared or raman). besides diamond and carbon nano tubes, cnts, one of the polymers which exhibit an almost threadlike character is poly-pxylylene, commercially denoted parylene, which has turned out a film with outstanding properties when compared to other synthetics. therefore, cvd deposition of parylene is making inroads in several technical fields. even applications demanding tight requirements on coating quality, like gate dielectrics for semiconductor industry and semi-permeable layers for drug eluting implants in medical science, are coming within its purview. plasma-enhancement of chemical vapor deposition has opened the window for coatings with remarkable surface qualities. in the case of diamond and cnts, their purity can be proven by spectroscopic methods. in all the other cases, quantitative measurements of other parameters of bulk or surface parameters, resp., are more appropriate to describe and to evaluate the quality of the coatings.
