Abstract:
1. A method, in a data processing system, for minimizing reliability problems in a three-dimensional (3D) integrated circuit, the method comprising: interrogating, by the processor, a set of sensors in the 3D integrated circuit for current data, wherein the 3D integrated circuit comprises two or more layers of active electronic components; determining, by the processor, a direction of force and a magnitude of the force based on the current data for each sensor in the set of sensors for each of one or more directions between the sensor and at least one neighboring sensor within the 3D integrated circuit architecture thereby forming a set of forces; using, by the processor, the set of forces to identify one or more points of stress that are at or above the predetermined force threshold; and responsive to identifying at least one point of stress that is at or above the predetermined force threshold, initiating, by the processor, one or more temperature actuation actions within the 3D integrated circuit in order to reduce the at least one point of stress in the region where the at least one point of stress is identified.
