Patent ID: 8318613

Claim:
A process for the manufacturing of a semiconductor device, comprising generating SiO 2 -layers or SiO 2 -lines on a substrate surface by applying a precursor composition comprising (A) a SiO 2 precursor or precursor mixture of the general formula (I) wherein independently from each other R A, AOA, Ar, AAr, AArA, AOAr, AOArA, AArOA, wherein A is linear or branched C 1 -C 18 -alkyl, or substituted or unsubstituted cyclic C 3 -C 8 alkyl; Ar is a substituted or unsubstituted aromatic group having 6-18 carbon atoms, and, n= 1−100 and wherein R may build a further direct bond to Si or to neighboring groups R and (B) a high boiling solvent or homogeneous solvent mixture with a boiling temperature >100° C. and <400° C., which is at least an alcohol or a homogeneous mixture of alcohols or a homogeneous mixture of at least one alcohol and at least one organic co-solvent or a homogeneous mixture of co-solvents and at least one alcohol, wherein said precursor composition is ink jet printable.
