Abstract
Abstract An apparatus for manufacturing semiconductor devices wherein a curing oven cures samples of dies bonded to lead frames by adhesives, a wire bonder which is installed adjacent to and in line with the curing oven wire-bonds the samples which have been cured in the curing oven, and a sample feeding mechanism feeds the samples to the curing oven and then to a wire-bonding section of the wire bonder; thus, there is no need for separate transport of the samples following curing or for repeated heating of the samples, and product reliability and productivity are improved. In addition, there is no need for a special curing oven or special measures to prevent oxidation following curing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
An apparatus for manufacturing semiconductor devices characterized in that said apparatus comprises a curing oven which cures samples consisting of dies bonded to lead frames by means of an adhesive, a wire bonder which is installed adjacent to and in line with said curing oven, said wire bonder wire-bonding said samples that have been cured by said curing oven, said wire bonder being further equipped with a bonding head which drives a bonding tool in X and Y directions and vertically, a sample-feeding mechanism which feeds said samples into said curing oven and from said curing oven into a bonding part of said wire bonder, a housing for said curing oven and said wire bonder, guide grooves formed in said housing for guiding said samples, a lid which is fastened to an upper surface of said housing, and a heating block provided in said housing.
Claim 2
Independent Claim
