Latest Patents

Zhigang Jiang's recent patents reflect his expertise in tackling complex challenges within integrated circuit technology. One notable patent describes a method and apparatus for testing 3D integrated circuits (3DIC). This invention uses time-division demultiplexing/multiplexing to apply high-data-rate scan patterns at input/output pads, which are then converted to low-data-rate patterns for each embedded module. Jiang has proposed a set of 3D design guidelines aimed at reducing testing times and the necessity for through-silicon vias (TSVs) during both pre-bond and post-bond testing phases. Notably, this technique allows for the reuse of scan patterns developed during pre-bond testing for the comprehensive testing of the entire 3DIC, thus minimizing test application duration while mitigating concerns regarding I/O pad count limits and fault coverage loss.

Another significant patent of Jiang includes an apparatus and method for protecting against soft errors. This invention offers resilience or correction for soft errors with capabilities for various testing operations, including slow-speed snapshot and signature analysis. The apparatus consists of a system circuit, a shadow circuit, and an output joining circuit designed for defect tolerance, thereby ensuring robust performance and reliability in circuit operation.
