Patent ID: 8017937

Claim:
A semi-conductor component having a metal-insulator structure (MIS), said semi-conductor component comprising: a substrate, a layer made of an organic semiconductor material, and a dielectric layer as insulator, wherein said substrate, said dielectric layer, or both said substrate and said dielectric layer comprise an organically modified silicic acid (hetero)polycondensate which can be obtained by: i) precondensation of a) 1 to 10% by mol of at least one silicon compound of formula I: MR 4 (I) wherein M is selected from silicon, zirconium, aluminum, and titanium, and R is a halogen, hydroxy, alkoxy, acyloxy, or a chelate ligand; b) 20 to 94% by mol of at least one organic silane of formula II: R″ m (YR′″) n SiX (4-m-n) (II) wherein R″ is alkyl, aryl, alkylaryl, or arylalkyl, R′″ is alkylene, alkenylene, arylene, alkylarylene, arylalkylene, alkenylarylene, or arylalkenylene, with R″ and R′″ each optionally being interrupted by oxygen, sulphur or —NH—, X is hydrogen, halogen, hydroxy, alkoxy, acyloxy, or —NR′ 2 , R′ is H or alkyl, Y is a polymerizable group, m is a whole number from 0 to 2, n is a whole number from 1 to 3, m+n is 1 to 3, c) 5 to 30% by mol of at least one organic silane of formula III R″ p SiX 4-p (III) wherein R′ and X have the meaning defined above, and p is 1, 2 or 3, and if necessary d) 0 to 10% by mol of at least one low volatile metal oxide, soluble in the reaction medium, of an element of groups Ia to Va or Vb, or of at least one compound, soluble in the reaction medium, of one of these elements which form a low volatile oxide; without external addition of water, if necessary in the presence of an organic solvent at a temperature between 0 and 90° C. during a time period between 0.5 and 48 hours, and (ii) hydrolysis condensation of the resultant precondensate with a stoichiometric quantity of water, at a temperature between 0 and 100° C. during a time period between 1 and 72 hours.
