The system includes multiple logical connections. The logical interconnections may be made with light transmission. A majority of physical connections may provide power. The physical interconnections may be sparse, periodic and regular. The exemplary system may include physical space (or gap) between the a pair of adjacent layers having few physical connections. The space may be generally set by the sizes of the connections. A constant flow of coolant (gaseous or liquid) may be maintained between the adjacent pair of layers in the space."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus to facilitate direct surface cooling of a chip within a 3D stack of chips using optical interconnect","description":"In one embodiment, the disclosure relates to a system of stacked and connected layers of circuits that includes at least one pair of adjacent layers having very few physical (electrical) connections.
