Abstract: An aluminum interconnection of the invention contains scandium as an impurity, so that the hardness of the interconnection is improved. Moreover, after a thin Al--Sc alloy film is formed, an annealing is performed so as to make the crystal grain larger than the width of the interconnection. The resulting Al interconnection has a high resistance against a stressmigration or electromigration, when a current stress is applied at a practical temperature in an LSI. This greatly contributes to the fabrication of a semiconductor device having a fine structure.

Abstract: The present invention provides an improved method for rapidly making an electrode for electrical discharge machining. According to the invention, a stereolithography process is used to make a cured resin model of the electrode and having a network of interconnected supporting members defining the shape of the electrode and leaving channels between the supporting members to drain away uncured resin from the model. After the model is fully cured and the uncured resin drained away, a slurry mixture of graphite and resin is infiltrated into the voids of the model. The resin is then heat cured so that the resin is burned away leaving the electrode of pure carbon. Alternatively, the graphite and resin mixture can be cured sufficiently to harden and then an electrically conductive metalized coating is applied on the outer surface.
