Disclosed is a non-photosensitive black electrode composition and a plasma display panel having a black electrode formed using the composition. The black electrode for the plasma display panel includes the non-photosensitive composition, thus yellowing does not occur on electrodes but conductivity to a transparent electrode layer is desirably assured even though typical conductive powder and various types of black pigments are used. It is possible to conduct patterning using a photolithography process due to the simultaneous development of black and bus electrodes, which can act as electrodes due to simultaneous sintering. Since it is non-photosensitive, it is possible to use various types of black pigments, thus the material cost is reduced.

Disclosed herein is a plasma display panel and a method of fabricating the same. The plasma display panel comprises a front glass substrate and a rear glass substrate. An electrode structure disposed between the front and rear glass substrates is prepared in such a way that a non-photosensitive black dielectric layer and a non-photosensitive or photosensitive electrode layer, formed on the front glass substrate, are subjected to heat treatment. The black dielectric layer is blackened at a surface in contact with the front glass substrate by the heat treatment. Current flows between an upper electrode and a transparent electrode and it is possible to assure sufficiently low visibility even though costly metal particles are not used as conductive material on the front substrate of the plasma display panel. It is possible to use various types of black pigments thanks to non-photosensitivity, thus it is possible to fabricate a low-priced plasma display panel due to a reduced material cost.

A method of forming a pad and a fuse in a semiconductor device. A copper layer located in both a fuse region and a pad region is formed in a dielectric layer. A first insulating layer is formed on the dielectric layer to cover the copper layer and selectively etched to expose the copper layer in the fuse region. An aluminum fuse is formed on the first insulating layer in the fuse region and connected to the exposed copper layer. A second insulating layer is formed on both the aluminum fuse and the first insulating layer and selectively etched together with the first insulating layer to expose the underlying copper layer in the pad region. An aluminum pad is formed on the second insulating layer in the pad region and connected to the exposed copper layer in the pad region. At least one third insulating layer is formed on both the aluminum pad and the second insulating layer and selectively etched to expose the aluminum pad only.
