摘要

本文提出了一种基于集成诊断与重构(IDAR)方法的从有缺陷的晶圆级集成处理器阵列构建无故障子阵列的新技术。在传统的良率增强方法中,它首先对所有单元进行诊断,然后将所有单元的状态(故障或无故障)传递给重构算法,以获得可能的重构解。IDAR方法的基础是可以在部分诊断信息下进行重构。系统分析已用于制定IDAR过程,并估计我们需要诊断所有单元的目标阵列的最小尺寸。我们还比较了我们的方法与其他策略的增产成本。

Integrated diagnosis and reconfiguration process for defect tolerant WSI processor arrays
This paper presents a new technique for constructing a fault-free subarray from a defective WSI (wafer scale integration) processor array based on an integrated diagnosis and reconfiguration (IDAR) method. In a traditional yield enhancement approach, it diagnoses all units first and then the status (faulty or fault-free) of all units are passed to the reconfiguration algorithm for a possible reconfiguration solution. The basis of the IDAR method is that reconfiguration can be performed under partial diagnosis information. Systematic analysis has been used to formulate the IDAR process and to estimate the minimal size of a target array at which we need to diagnose all units. We also compare the yield enhancement cost of our approach with that of other strategies.<>
