Abstract:
A semiconductor device comprising:(a) a polybenzoxazole resin film for chip protection, obtained by coating, on a circuit-formed chip, a positive photosensitive resin composition comprising 100 parts by weight of a polyamide represented by the following general formula (1) and 1 to 100 parts by weight of a photosensitive diazoquinone compound, and subjecting the coated composition to patterning and curing, and (b) a bump electrode: wherein X is a tetravalent aromatic group; Y is a bivalent aromatic group; Z is (R1 and R2 are each a bivalent organic group, and R3 and R4 are each a monovalent organic group); E is a carboxyl aliphatic, alicyclic or aromatic group having at least one alkenyl or alkinyl group; and a and b are each a molar fraction, a+b=100 mole %, a=60.0 to 100.0 mole % and b=0 to 40.0 mole %; and n=2 to 500.
