摘要:
Methods are disclosed for improving electrical interconnection in stacked die assemblies, and stacked die assemblies are disclosed having structural features formed by the methods. The resulting stacked die assemblies are characterized by having reduced electrical interconnect failure.
摘要:
A microelectronic package includes a subassembly, a second substrate, and a monolithic encapsulant. The subassembly includes a first substrate that has at least one aperture, a coefficient of thermal expansion (CTE) of eight parts per million per degree Celsius or less, and first and second contacts arranged so as to have a pitch of 200 microns or less. First and second microelectronic elements are respectively electrically connected to the first and second contacts. Wire bonds may be used to connect the second element contacts with the second contacts. A second substrate may underlie either the first or the second microelectronic elements and be electrically interconnected with the first substrate. The second substrate may have terminals configured for electrical connection to a component external to the microelectronic package. A monolithic encapsulant may contact the first and second microelectronic elements and the first and second substrates.
摘要:
Methods and apparatus for increasing the yield achieved during high density interconnect (HDI) production. In particular, processes in which panels are tested to identify good cells/parts, good cells are removed from the panels, and new panels created entirely of identified/known good cells allow increases in the number of layers used in a HDI without incurring the decrease in yield normally associated with such a layering process.
