Abstract: A method for circuit die stacking can include providing a first circuit die having a first metal stack, wherein the first circuit die corresponds to a primary thermal source of an integrated circuit including the first circuit die. The method can additionally include providing a second circuit die of the integrated circuit, wherein the second circuit die has a second metal stack and is configured for connection to at least one of a package substrate or an additional die. The method can also include connecting the first metal stack to the second metal stack. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method for die pair partitioning can include providing a first circuit die having a first metal stack. The method can additionally include positioning a second circuit die having a second metal stack in a manner that places a temperature sensor in a transistor layer of the second circuit die in planar proximity to at least one hot spot located in an additional transistor layer of the first circuit die. The method can also include connecting the first metal stack of the first circuit die to the second metal stack of the second circuit die. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A network of thermal sensors can be integrated within a semiconductor chip in a manner effective to provide local temperature monitoring and dynamic control of an associated device or system. The thermal sensors can include small area thermal ring oscillators located proximate to the core of a central processing unit (CPU), for example, and can be disposed on the chip at locations based on a designed output power density and attendant thermal gradients encountered during operation. In certain implementations, the presently-disclosed sensor configuration can be used to measure deviation from set threshold temperatures. Closed-loop control can be implemented to mitigate performance loss while adjusting the clock speed of the CPU independent of the system management unit.
