Abstract:
A method for fabricating electro-mechanical structures comprising a plurality of modules, each of said modules having a plurality of via holes therein, said via holes traversing from a module first surface through to a second surface and positioned in at least one substantially same location within each of said plurality of modules, said method comprising the steps of:arranging said plurality of modules in a stacked fashion, wherein selective via holes in adjoining modules are flushly engaged to provide at least one communication path between at least one first module and at least one disposed module through via holes of intervening modules, said arranging further comprising associating at least one integrated circuit die with at least one of said plurality of modules; placing said at least one integrated circuit die within at least one well created in said first surface; covering said at least one well such that said covering and said first surface are substantially flush; creating a cavity in said second surface in opposition to each of said placed integrated circuit dies, wherein said cavity is sized substantially equal to a corresponding covering.
