Reliability improvement of polymer-based capacitors by moisture barrier
It has been discovered that poor TDDB reliability of microelectronic device capacitors with organic polymer material in the capacitor dielectric is due to water molecules infiltrating the organic polymer material when the microelectronic device is exposed to water vapor in the operating ambient. Water molecule infiltration from water vapor in the ambient is effectively reduced by a moisture barrier comprising a layer of aluminum oxide formed by an atomic layer deposition (ALD) process. A microelectronic device includes a capacitor with organic polymer material in the capacitor dielectric and a moisture barrier with a layer of aluminum oxide formed by an ALD process.
IGBT assembly having saturable inductor for soft landing a diode recovery current
A combination switch includes an Insulated Gate Bipolar Transistor (IGBT), an anti-parallel diode, and a saturable inductor. The diode and inductor are coupled in series between a collector and an emitter of the IGBT. The inductor is fashioned so that it will come out of saturation when a forward bias current flow through the diode falls below a saturation current level. When the diode current falls (for example, due to another combination switch of a phase leg turning on), the diode current initially falls at a high rate until the inductor current drops to the saturation current level. Thereafter, the diode current falls at a lower rate. The lower rate allows the diode current to have a soft landing to zero current, thereby eliminating or reducing voltage and/or current spikes that would otherwise occur. Multiple methods of implementing and manufacturing the saturable inductor are disclosed.

The third resin portion surrounds the element-mounting region. Each of the first and second leads includes a first plating and a second plating covering at least a portion of the first plating. The wire-connecting region is located outward of the third resin portion. The element-mounting region is located on an outermost surface of the second plating. In a top view, the wire-connecting region is located laterally inward of a portion of the second plating of the second lead that has an outermost surface located higher than that of the first plating of the second lead.
