Unlike silicon-based materials where selective reactants are of ultimate importance, and III-V and metallic materials where product volatility dominates etching considerations, selective etching of organic films is driven by incorporating the desired reactivity (or lack of it) into the film itself. In device fabrication all types of materials are present simultaneously and the process engineer must be aware of the important aspects of the chemistry of each material in addition to the gas phase reactions that produce chemically active species. It is hoped that the discussions presented here provide a basis for approaching such a complex chemical system and for critically evaluating studies which appear in the literature.

Silicon-based materials (silicon carbide, silicon nitride) usually form a superficial film of silicon dioxide that protects the material against corrosion in acidic or neutral media. At pH equal to or higher than eleven it suffers corrosion heavily because the silicon dioxide is dissolved [25],...

Partially functionalized cyclopolysilanes recently attracted attention as model substances for siloxene and luminescent silicon. The yellow luminescent silicon is formed by the anodic oxidation of elemental silicon in HF-containing solutions and may be used for the development of silicon-based materials for light-emitting structures which could be integrated into optoelectronic devices77. Because the visible photoluminescence of...

Interest in silicon-based materials has established an international conununity whose roots initially dug in organic and silicon chemistry, polymer and sol-gel chemistry, and material science. This fact led Prof. Interrante and Prof. Kawakami to launch a series of workshops that began in Tatsunokuchi, Japan, in 1999 as a satellite workshop to the XU" International Symposium on Organosilicon Chemistry in Sendai. The first workshop was attended by over 100 participants from Asia, Europe, and the USA and its success emphasized the perceived need for a continuing forum for organosilicon polymer research a decision was then taken to maintain these workshops on a bi-annual basis. The second and third workshops were held in Canterbury, UK, in 2001, and Troy, USA, in 2003, both workshops achieved a similarly strong international participation. 

The contributions in this book reflect the diversity of silicon-based materials and the new developments in the strategies and concepts at work. 

Polysiloxanes (silicones) are highly hydrophobic, inert polymers. As aresult, many silicone-based materials display good water repellency and weather resistance. Furthermore, the polysiloxane chain s flexibility gives rise to the macroscopic properties of smoothness and Inbricity. This makes silicones attractive candidates for the modification of snrfaces, snch as textiles, paper and leather. Polysiloxanes, however, have poor adhesive properties, dne to their limited interaction with other materials. Functional gronps have to be introdnced for this purpose. They are inserted at the end of the silicone polymer chain or into the side chains.
