摘要： A surplus liquid reservoir attached to a vapor chamber integrated heat spreader (IHS) and placed near a heat source on a heterogenous die. The vapor chamber integrated heat spreader (IHS) includes a main heat transfer portion that encloses a vapor channel, a first wick material, and a first working fluid. The surplus liquid reservoir is provided by a reservoir leg mechanically coupled, on a first side, to the main heat transfer portion, the reservoir leg has a reservoir portion with a second working fluid and second wick material that is in contact with the first wick material. The surplus liquid reservoir can either support a PL2 that is higher than a given vapor chamber Qmax for a significantly long time or increase the PL2 value to a significantly higher value.

The disaggregated IC dies are surrounded laterally by a dielectric material, and the disaggregated IC dies are arranged with portions of the monolithic wafers such that a voltage regulator circuit in a first layer of the plurality of layers, a compute circuit in a second layer of the plurality of layers, and a memory circuit in a third layer of the plurality of layers are conductively coupled together in an intra-modular power delivery circuitry.
