Patent ID: 8703367

Claim:
A positive photosensitive resin composition comprising: (A) a polybenzoxazole precursor including a repeating unit represented by the following Formula 1; (B) a photosensitive diazoquinone compound; (C) a silane compound; (D) a polyamic acid ester compound; and (E) a solvent, wherein in the above Formula 1: X 1 is an aromatic organic group, a tetravalent to hexavalent aliphatic organic group, an alicyclic organic group including a hetero atom, or a tetravalent to hexavalent aliphatic organic group including a hetero atom; X 2 is an aromatic organic group, a divalent to hexavalent aliphatic organic group, an alicyclic organic group including a hetero atom, a divalent to hexavalent aliphatic organic group including a hetero atom, or a group represented by the following Formula 2; Y 1 and Y 2 are the same or different and are independently an aromatic organic group, a divalent to hexavalent aliphatic organic group, an alicyclic organic group including a hetero atom, or a divalent to hexavalent aliphatic organic group including a hetero atom; m1 and m2 are respectively mole ratios, where m1+m2 is 100 mol %; m1 ranges from 60 to 100 mol %; and m2 ranges from 0 to 40 mol %, wherein, in the above Formula 2: R 1 to R 4 are the same or different and are independently substituted or unsubstituted alkyl, substituted or unsubstituted aryl, substituted or unsubstituted alkoxy, or hydroxy; R 5 and R 6 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.
