As the increase of power densities became the primary constraint for semiconductor industry to sustain the Moore's law for microprocessor evolution, multi-core architecture has been introduced in order to meet the growing demands for performance. Non-uniform power distribution, increased die-size and multiple-chip packaging present new challenges for the thermal management of modern CPUs. Further...
Driven by shrinking feature sizes, microprocessor "hot-spots" - with their associated high heat flux and sharp temperature gradients - have emerged as the primary "driver" for on-chip thermal management of today's advanced IC technology. Proposed uses of solid state thermoelectric microcoolers for hot spot remediation have included the formation of a superlattice layer on the back...
Integrating microchannels at the thermal interfaces of heat sinks, spreaders, and microprocessor chips can reduce bond line thickness, assembly pressure, and overall thermal resistance. The channels help control the flow of particle-filled thermal interface materials (TIM) during the assembly squeeze but the relationship between channel geometry, material properties, and interfacial area is not fully...
Microprocessors continue to grow in capabilities, complexity and performance. Microprocessors typically integrate functional components such as logic and level two (L2) cache memory in their architecture. This functional integration of logic and memory results in improved performance of the microprocessor. However, the integration also introduces a layer of complexity in the thermal design and management...
