Abstract: The present invention relates to methods of derivatizing semiconductor surfaces, particularly porous silicon surfaces with silicon-carbon units. The derivatization occurs through the direct addition of an organometallic reagent in the absence of an external energy source such as heat and photo- or electrochemical energies. The method of the invention allows the formation of unique intermediates including silicon hydride units bonded to metal ions. Because of these unique intermediates, it is possible to form previously inaccessible silicon-carbon units, for example where the carbon atom is an unsaturated carbon atom. Such inaccessible silicon-carbon units also include silicon-polymer covalent bond formation, in particular where the polymer is a conducting polymer. Thus, the present invention also provides a novel semiconductor surface/polymer junction having improved interfacial interactions.

In a fourth step, the binder is burnt off from the rubbery layer at elevated temperature. In a fifth step, the layer from which the binder has been burnt off is set at elevated temperature. In a sixth and a seventh step, the layer which has been set is processed in accordance with the dimensions of the insulating component and consolidated by sintering.

Abstract: A fibrous ceramic mat is molded from a slurry of ceramic fibers and/or ceramic microparticles and/or a metal. The mat is impregnated with a sol prior to drying. A catalyst for the sol is introduced into the mat to cause the sol to gel. The sol-gel binder forms bonds so that the mat is dimensionally stabilized. The mat is dried to produce the desired ceramic insulation that has preferably a consistent microstructure and a fully gelled sol-gel binder through its entire thickness. If we use a metal, it corrodes (i.e., oxidizes) or otherwise reacts to form a refractory binder that augments the sol and reduces the need to infuse sol incrementally to achieve strength. Using metal powder significantly reduces the cost of manufacture.
