It is shown that intermetallic compound crystallization correlates with bonding duration, as a longer duration is applied, alumina fragmentation becomes pervasive, resulting in continuous alloy interfaces and robust bonds. Abstract The effect of bonding duration and substrate temperature on the nano-scale interfacial structure for bonding strength were investigated using high resolution ...
Spiral inductors were fabricated by burying thick metals in radio frequency (RF) package substrates. The inductors consist of a 40-μm-thick copper spiral buried in an anodized aluminum substrate and an overpass supported by a benzocyclobutene layer on top of the substrate. Due to their low ohmic loss, significantly high Q factors were obtained at 2 GHz: a Q factor of over 100 with 4.2-nH ...
Aluminum is a relatively soft, durable, lightweight, ductile and malleable metal that is easily machined, cast, drawn and extruded. It is nearly always alloyed to improve its mechanical properties. Aluminum resists corrosion because a thin layer of aluminum oxide forms almost immediately when the bare metal is exposed to air.
