Abstract: An improved semiconductor device is described. That semiconductor device includes a first insulating layer, having a low-k dielectric constant that preferably comprises a carbon doped oxide, that is formed on a substrate. The device further includes a second layer, which is formed on the first layer, that has a relatively high dielectric constant and superior mechanical strength. The second layer is preferably under compressive stress. A third layer may be formed on the second layer, which has a relatively low dielectric constant and relatively poor mechanical strength, and a fourth layer may be formed on the third layer, which has a relatively high dielectric constant and superior mechanical strength.

Abstract: A method of fabricating microelectronic dice by providing or forming a first encapsulated die assembly and a second encapsulated die assembly. Each of the encapsulated die assemblies includes at least one microelectronic die disposed in an encapsulation material. Each of the encapsulated die assemblies has an active surface and a back surface. The encapsulated die assemblies are attached together in a back surface-to-back surface arrangement. Build-up layers are then formed on the active surfaces of the first and second encapsulated assemblies, preferably, simultaneously. Thereafter, the microelectronic dice are singulated, if required, and the microelectronic dice of the first encapsulated die assembly are separated from the microelectronic dice of the second encapsulated die assembly.
