Patent ID: 7427443

Claim:
A semiconductor device, comprising: a wiring structure comprising a first wiring layer formed on a surface of a semiconductor region forming an active component or a passive component, and a second wiring layer formed in an upper layer of the first wiring layer, a first insulating structure insulating the semiconductor region and the first wiring layer, a second insulating structure insulating an interlayer formed of the first wiring layer, a third insulating structure contained in a structure electrically insulating the first wiring layer and the second wiring layer and forming connecting holes electrically connecting the first wiring layer and the second wiring layer, and a fourth insulating structure insulating an interlayer formed with the second wiring layer, and comprising in one of the second, third and fourth insulating structures an insulating material, said insulating material comprising: a borazine-silicon polymer obtained by hydrosilylation polymerization of a borazine compound represented by chemical formula 1 possessing an alkyl group for a nitrogen atom and an alkyl group-substituted triple bond-containing organic group for a boron atom in a borazine ring, in which the boron atom has an acetylene group directly linked thereto or R 2 and an acetylene group jointly linked thereto; and a silicon compound represented by chemical formula 2 possessing at least two hydrosilyl groups or a cyclic silicon compound represented by chemical formula 3 possessing at least two hydrosilyl groups; in which: R 1 denotes an alkyl group, R 2 denotes —(CH 2 )-m (m denoting an integer of 0 or more), R 3 denotes an alkyl group linked to an acetylene group, R 4 and R 5 each denote one identical or different monovalent group selected from the group consisting of an alkyl group, an aryl group, an aralkyl group and a hydrogen atom, R 6 denotes a divalent aromatic group optionally possessing a substituent group, an oxygen atom, a siloxane or an oxypoly(dimethyl siloxy) group, and R 7 denotes an alkyl group, an aryl group or an aralkyl group; wherein chemical formula 1 is as follows wherein chemical formula 2 is as follows wherein chemical formula 3 is as follows
