Abstract

PURPOSE:To prevent the deformation and the damage of a projected solder electrode due to a probing in a semiconductor element and to increase the reliability of the device by forming a probing pad formed in height lower than the projected electrode separately at the position from the projected electrode at the periphery of a substrate provided with the projected solder electrode. CONSTITUTION:An aluminum wire 14 connected to an element substrate 10 through a window is formed on an insulating film 12 on the substrate 10, and a metallic layer 18 of three layers (Ti-Cu-Ti) connected to the aluminum wire layer 14 through the window of a passivation layer 16. A solder bump 20 is formed on a part of the layer 18 by removing the Ti layer on the upper layer, and a probing solder pad 22 having a height higher than the bump 20 and an area smaller than that is formed in the vicinity of the substrate of the layer 18. When the element is tested for probing, a probing stylus is contacted with the pad 22. In this manner, the deformation and the damage can be eliminated at the bump 20, and the decrease in the reliability of the element due to the probing can be prevented.
