Semiconductor device and modification of function thereof

Abstract

Abstract PURPOSE:To enable to easily perform modification of the function of a semiconductor device by a method wherein at least parts of the signal lines of the semiconductor device, which is constituted by forming plural conductive wiring layers, are constituted as the uppermost layers of the conductive wiring layers. CONSTITUTION:Input signal lines 3 and 7 have been respectively connected to lowest-layer conductive layers 10 and 11 and intermediate-layer conductive layers 12 and 13 through contact holes. The conductive layer 3 on one side has been connected to a conductive layer 15, which is another intermediate layer, through conductive layers 14 and 14' formed in a bridge form. That is, this means that the signal lines 3 and 7 have been constituted in such a way that parts of each of the signal lines are used as the uppermost-layer conductive layers. Accordingly, in case the function of the semiconductor device is modified, the modification has only to cut one part of the uppermost-layer wiring or to anew provided an uppermost-layer wiring.
