Patent ID: 8525320

Claim:
A stacked system of microelectronic die packages, comprising: a first die package including a first die and a first dielectric casing at least partially covering the first die, first lateral sides along the first dielectric casing, and first metal contacts having first lateral contact surfaces along the first lateral sides of the first dielectric casing; a second die package including a second die and a second dielectric casing at least partially covering the second die, second lateral sides along the second dielectric casing, and second metal contacts having second lateral contact surfaces along the second lateral sides of the second dielectric casing, wherein the second die package is stacked on top of the first die package and the first metal contacts are at least generally aligned with corresponding second metal contacts; a third die package including a third die and a third dielectric casing at least partially covering the third die, third lateral sides along the third dielectric casing, and third metal contacts having third lateral contact surfaces along the third lateral sides of the third dielectric casing wherein the third metal contacts are at least generally aligned with corresponding first metal contacts; and metal solder connectors including first-set connectors and second-set connectors, wherein the first-set connectors are coupled to individual first metal contacts and individual second metal contacts, and wherein the second-set connectors are coupled to individual first metal contacts and individual third metal contacts, and wherein at least a portion of the first-set connectors contacts the first and second lateral contact surfaces, and wherein at least a portion of the second-set connectors contacts the first and third lateral contact surfaces, and wherein the first-set connectors are physically and electrically isolated from the individual third metal contacts while the second-set connectors are physically and electrically isolated from the individual second metal contacts.
