Abstract:
1. A positive photosensitive siloxane composition comprising polysiloxane (I), a diazonaphthoquinone derivative (II), and a solvent (III), wherein the polysiloxane (I) contains at least one of polysiloxane (Ia) below, at least one of polysiloxane (Ib) below, and at least one of polysiloxane (Ic) below, (A) Polysiloxane (Ia): a polysiloxane, where a prebaked film of which is soluble in a 5 wt % tetramethylammonium hydroxide aqueous solution and which has a dissolution rate of 1,000 Å/second or less in a 5 wt % tetramethylammonium hydroxide aqueous solution and is obtained by hydrolyzing and condensing, in the presence of an acidic or basic catalyst, a silane compound represented by the formula (1); wherein R 1 represents a linear, branched or cyclic alkyl group having 1 to 20 carbon atoms, in which any methylene group may be replaced by an oxygen atom, or an aryl group having 6 to 20 carbon atoms, in which any hydrogen atom may be replaced by a fluorine atom, R 2 represents an alkyl group having 1 to 5 carbon atoms, and n is 0 or 1, (B) Polysiloxane (Ib): a polysiloxane, where a prebaked film of which has a dissolution rate of 4,000 Å/second or more in a 2.38 wt % tetramethylammonium hydroxide aqueous solution and which is obtained by hydrolyzing and condensing the silane compound represented by the formula (1) in the presence of an acidic or basic catalyst, (C) Polysiloxane (Ic): a polysiloxane, where a prebaked film of which has a dissolution rate of 200 Å/second or more and 3,000 Å/second or less in a 2.38% tetramethylammonium hydroxide aqueous solution and which is obtained by hydrolyzing and condensing the silane compound represented by the formula (1) in the presence of an acidic or basic catalyst.
