    摘要: An electronic apparatus includes first and second level package structures and an LGA (land grid array) interposer. The first level package structure includes a package substrate, one or more integrated circuit chips mounted on a first surface of the package substrate, and a first pattern of I/O contacts with pitch P1 formed on a second surface of the package substrate opposite the first surface. The second level package structure includes a second pattern of I/O contacts with pitch P2, wherein P2 is not equal to P1. The LGA interposer is disposed between the first and second level package structures and provides space transform electrical interconnections between the first second patterns of I/O contacts, and further includes a dummy contact formed on at least a first or second surface of the LGA interposer and aligned to an LGA contact on an opposing surface of the LGA interposer.

    摘要: In an integrated circuit structure, such as in an MCM or in an SCM, a particulate thermally conductive conformable material, such as a thermal paste, is applied between a heat-generating chip and a cooling plate. Modification of the microstructure of at least one of the two nominally parallel surfaces which are in contact with the material is provided in a discrete pattern of sloped recesses. The largest particles in the material preferentially migrate downward into the recesses. The average thickness of the conductive paste is reduced to below the diameter of the largest particles dispersed in the material, providing improved cooling.
