SEMICONDUCTOR APPARATUS CAPABLE OF ERROR REVISION USING PIN EXTENSION TECHNIQUE AND DESIGN METHOD THEREFOR

摘要

1. A semiconductor device comprising a plurality of metal layers, comprising: at least one repair block performing a predetermined function; A spare block replacing the predetermined function of the repair block; And at least one repair layer predefined for error correction among the plurality of metal layers, wherein at least one pin of the repair block is connected to the repair layer via a first pin extension, and at least one of the spare blocks Wherein one pin is configured to extend to the repair layer and upon release of the repair block, disconnects the first pin extension between the repair layer and the repair block, and the at least one pin of the spare block And connected to the repair layer through a second pin extension. If there is an error after fabricating the semiconductor device, only one layer or more of the metal layer that is predetermined can be reproduced, and the error can be corrected at a low cost within a short correction period.;Semiconductor chip, repair block, error correction, spare block, pin extension, repair layer
