TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The used two- to four-fold symmetrically and/or asymmetrically substituted alkoxysilanes and alkoxyalkylsilanes comprises saturated, unsaturated, branched, unbranched, aliphatic, alicyclic and aromatic groups, which are functionalized at a position of the alkyl group or alkoxide group by heteroatoms comprising oxygen, nitrogen, sulfur, chlorine or bromine. The strong carboxylic acid salts comprises formic acid, acetic acid, oxalic acid, trifluoroacetic acid, mono-, di-and trichloroacetic acid, glyoxylic acid, tartaric acid, maleic acid, malonic acid, pyruvic acid, malic acid or 2-oxoglutarate. The printable oxide medium is produced based on hybrid sols and or -gels using alcoholates/esters, acetates, hydroxides or oxides of aluminum, germanium, zinc, tin, titanium, zirconium or lead. Preferred Method: The pasty, highly viscous medium are converted into diffusion barriers after printing. The oxide medium is distilled to a highly viscous, glass-type composition, and the obtained product is brought back into solution either by addition of a suitable solvent or solvent mixture or is transformed in a sol state by means of intensive shear mixing devices and is converted into a homogeneous gel by partial or complete structure back recovery (gelation). The formulation of the highly viscous oxide mediums is led without additional thickeners. The method produces stable mixture, which is storage stable for a period of at least three months. EXAMPLE - 51.4 g L-(+)-tartaric acid was weighed in a round bottom flask and 154 g dipropylene glycol monomethyl ether and 25 g tetraethyl orthosilicate were added. The reaction mixture was stirred for 90 hours and heated to 90 degrees C to obtain a transparent solution. The mixture was gelled completely. The obtained gel was homogenized in a mixer under high shear, and printed on one side of polished monocrystalline wafers. The wafers were dried on a hot plate at 300 degrees C for 2 minutes and the layer was etched and removed using dilute hydrofluoric acid to obtain low viscosity doping medium.
