Patent ID: 8198002

Claim:
A positive photosensitive resin composition comprising: (A) a first polybenzoxazole precursor that includes a repeating unit of the following Chemical Formula 1, and a thermally polymerizable functional group at at least one terminal end; (B) a second polybenzoxazole precursor that includes a repeating unit of the following Chemical Formula 3; (C) a photosensitive diazoquinone compound; (D) a silane compound; and (E) a solvent: wherein, in the above Chemical Formula 1, X1 is an aromatic organic group or a tetravalent to hexavalent alicyclic organic group, Y1 and Y2 are the same or different, and are independently an aromatic organic group or a divalent to hexavalent alicyclic organic group, X2 is an aromatic organic group, a divalent to hexavalent alicyclic organic group, or a functional group represented by the following Formula 2, m1 and n1 are each mole ratios, and m1+n1 is 100%, m1 ranges from about 60 to about 100 mol %, and n1 ranges from about 0 to about 40 mol %: wherein, in the above Chemical Formula 2, R1 to R2 are the same or different, and are independently substituted or unsubstituted alkyl, substituted or unsubstituted aryl, substituted or unsubstituted alkoxy, or hydroxy, R3 and R4 are the same or different, and are independently substituted or unsubstituted alkylene or substituted or unsubstituted arylene, and k is an integer ranging from 1 to 50; wherein, in the above Chemical Formula 3, X3 and X4 are the same or different, and are independently an aromatic organic group or a tetravalent to hexavalent alicyclic organic group, Y3 is an aromatic organic group or a divalent to hexavalent alicyclic organic group, and wherein Y3 further includes a thermally polymerizable organic group, Y4 is an aromatic organic group or a divalent to hexavalent alicyclic organic group, m2 and n2 are each mole ratios, and m2+n2 is 100 mol %, m2 ranges from about 50 to about 100 mol %, and n2 ranges from about 0 to about 50 mol %.
