Appeal No. 2003-0543 Application 09/292,745 The claimed invention relates to a semiconductor device which is provided with copper traces for connecting active elements to an external device. More particularly, insulating layers of black oxide (cupric oxide) are formed on the copper traces, the black oxide functioning as a substitute for the conventionally used solder resist mask. Claim 1 is illustrative of the invention and reads as follows: 1. A semiconductor device, comprising: semiconductor active elements; metal traces for connecting said active elements to an external device, wherein said metal is copper; and insulating layers on said metal traces, said insulating layers including black oxide, wherein said black oxide is a substitute for a solder resist mask.
