The present invention is a method for providing an integrated circuit assembly, the integrated circuit assembly including an integrated circuit and a substrate. The method includes mounting the integrated circuit to the substrate. The method further includes, during assembly of the integrated circuit assembly, applying a low processing temperature, at least near-hermetic, glass-based coating directly to the integrated circuit and a localized interconnect interface, the interface being configured for connecting the integrated circuit to at least one of the substrate and a second integrated circuit of the assembly. The method further includes curing the coating. Further, the integrated circuit may be a device which is available for at least one of sale, lease and license to a general public, such as a Commercial off the Shelf (COTS) device. Still further, the coating may promote corrosion resistance and reliability of the integrated circuit assembly.
