PURPOSE: A method for manufacturing a semiconductor device using dual damascene technology is provided to prevent an over-etch of a lower interconnection by using an etch stopping layer composed of an N-doped SiC layer. CONSTITUTION: An etch stopping layer(23) and an interlayer dielectric(26) are sequentially formed on a semiconductor substrate(100) having a lower conductive layer(20). A via hole(30) is formed to expose the etch stopping layer(23) by selectively etching the interlayer dielectric. A second photoresist pattern(32) is formed to expose portions of the interlayer dielectric(26) on the resultant structure. At this time, a photoresist residue(34) is remaining in the via hole. A groove(36) is formed by etching the exposed interlayer dielectric(26) using the second photoresist pattern(32) and the photoresist residue(34) as a mask. After removing the second photoresist pattern(32) and the photoresist residue(34), the surface of the lower conductive layer(20) is exposed by removing the exposed etch stopping layer(23). An N-doped SiC layer is used as the etch stopping layer(23).

PURPOSE: A wire bonder is to accomplish excellent formation of a wire ball and to prevent a defective wire bonding by including a heating element which removes humidity of a wire. CONSTITUTION: A wire bonder(30) connecting a chip pad(12) of a semiconductor chip(11) to a lead(13) of a lead frame by a wire(10) comprises a heating element(40) which forms a wire ball(10a) excellently by removing humidity of the wire. The wire wound around and supplied from a spool(34) enters between the clamps and passes through a capillary(31) disposed below the clamps. The clamp picks up and fixes the bonded wire to cut it. A through hole(31a) is provided on the capillary to which a vibrator(35) for applying a supersonic vibration is fastened. A torch(33) arranged under the capillary applies a flame to a tip of the wire to form a wire ball(10a). A heater block(36) also applies heat to the chip and the lead. The heating element includes a metal cylinder having a coated film on its outside. The heating element further comprises a gas spraying nozzle which sprays a gas to the wire to remove the humidity therefrom.
