STRUCTURED INTEGRATED CIRCUIT DEVICE WITH MULTIPLE CONFIGURABLE VIA LAYERS

摘要

An integrated circuit may include a multi-layer structure having alternating metal interconnection layers and via layers superimposed on a base layer having electronic components, functional blocks, or both. At least two of the via layers may be customizable and may be used to form customized interconnections that may customize functionality of the resulting integrated circuit. In a variant, at least some of the layers may have a default structure that may result in a default integrated circuit functionality; the default structure may be changed to customize functionality. One or more metal interconnection layers may also be customizable. Additionally, transistors of the base layer may be customized for speed and/or power consumption by adjusting voltage thresholds and/or gate lengths.
