Abstract
Two or more integrated circuits are stacked into a high density circuit module. The lower IC is inverted. Electrical connection to the integrated circuits is made by module contacts on a flexible circuit extending along the lower portion of the module. In one embodiment, the flexible circuit provides a balanced electrical connection to two CSP integrated circuits. In another embodiment, the flexible circuit provides a balanced electrical connection to inter-flex contacts of additional flexible circuits on two submodules. The additional flexible circuits provide further balanced connections to CSP integrated circuits in each submodule.
