In nature, carbon has two crystalline allotropes, diamond and graphite, with vastly different properties. However, through chemical or physical vapour deposition (CVD PVD) a third state, diamondlike (DLC), can be synthesised at low temperatures. There are kinds of DLC films, one relatively large amount (up to 50 at.-%) hydrogen which is thus named hydrogenated DLC, a-C: H, the other essentially without inclusion non-hydrogenated a-C (amorphous carbon). basic ways synthesise DLCcoating:...

Thermally stressed high-density multi-tier copper wire bonded IC packages are the most challenging tasks in package decapsulation. For acid decapsulation, hardening of epoxy molding compound after stress tests requires much longer etching duration. As a result, bond wires suffer severe corrosion damage compared to un-stressed counterparts. plasma block radicals reach beneath loops. consequence, residues around Cu/Al ball bonds become impossible remove.
