    • PROBLEM TO BE SOLVED: To shorten the trimming time to adjust circuit characteristics.SOLUTION: A semiconductor device comprises a ladder fuse LFA whose break points are arranged along a coordinate Y1 and a ladder fuse LFB whose break points are arranged along a coordinate Y2. When compensation data to adjust circuit characteristics fall within a first range, a trimming operation is performed to both the ladder fuses LFA and LFB. When the compensation data to adjust the circuit characteristics fall within a second range, the trimming operation is performed to the ladder fuse LFB without performance of the trimming operation to the ladder fuse LFA. For this reason, when the compensation data fall within the second range, there is no need for laser irradiation to the ladder fuse LFA. Therefore, for example, the assignment of the adjustment range required for a mass production step to the ladder fuse LFB enables the completion of the trimming by one scan.
    • 要解决的问题:缩短调整时间以调整电路特性。 解决方案:半导体器件包括梯形保险丝LFA,其断点沿着坐标Y1布置,梯形保险丝LFB的断点沿着坐标Y2排列。 当调整电路特性的补偿数据落在第一范围内时,对梯形保险丝LFA和LFB进行修整操作。 当调整电路特性的补偿数据落在第二范围内时,对梯形保险丝LFB进行修整操作,而不对梯形保险丝LFA进行修整操作。 因此,当补偿数据落入第二范围内时,不需要对梯形保险丝LFA进行激光照射。 因此,例如,将批量生产步骤所需的调整范围分配给梯形熔丝LFB能够通过一次扫描来完成修整。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a laminated memory capable of avoiding an increase of a chip size by laminating private fuse chips and memory core chips to carry out an interconnection with small number of bonding signals between the chips.
      SOLUTION: The laminated memory is provided with a configuration by laminating: memory core chips MC provided with memory cell arrays 20 including backup memory cells for replacing failure memory cells; and fuse chips HC provided with a fuse part capable of establishing an electric cutting state corresponding to a replacement to the backup memory cells and a relief control circuit controlling a relief performance of the failure memory cells based on state information of this fuse part. Such a constituted lamination memory can reduce a size by making a loading of a fuse element and the relief control circuit on the memory core chips MC unnecessary and can reduce the number of the bonding signals between the chips between the memory core chips MC and the fuse chips HC.
