Reliable device assembly
View Patent ↗Microelectronic assemblies and methods for making the same are disclosed herein. In one embodiment, a method of forming a microelectronic assembly comprises assembling first and second components to have first major surfaces of the first and second components facing one another and spaced apart from one another by a predetermined spacing, the first component having first and second oppositely-facing major surfaces, a first thickness extending in a first direction between the first and second major surfaces, and a plurality of first metal connection elements at the first major surface, the second component having a plurality of second metal connection elements at the first major surface of the second component; and plating a plurality of metal connector regions each connecting and extending continuously between a respective first connection element and a corresponding second connection element opposite the respective first connection element in the first direction.
1. A microelectronic assembly, comprising:
a first component having first and second oppositely-facing major surfaces, a first thickness extending in a first direction between the first and second major surfaces, and a plurality of first metal connection elements at the first major surface;
a second component having a first major surface and a plurality of second metal connection elements at the first major surface of the second component,
the first major surfaces of the first and second components facing one another;
a plurality of plated metal connectors each connecting and extending continuously in the first direction between a respective first metal connection element and a corresponding second metal connection element opposite the respective first metal connection element; and
a plurality of metallic barrier layers overlying continuously at least some of the plated metal connectors and the first and second metal connection elements in the first direction, each barrier chemically insulating a corresponding plated metal connector.
2. The assembly according to claim 1 , wherein the first component and the plated metal connector are non-electrical non-thermal components for mechanical support.
