    Abstract: A drive circuit having asymmetrical drivers. In an embodiment, a brushless DC motor may be driven by a drive circuit having three high-side MOSFETs and three low-side MOSFETs. A driver controller turns the MOSFETs on and off according to a drive algorithm such that phase currents are injected into motor coils to be driven. The high-side MOSFETs may be sized differently than the low-side MOSFETs. As such, when a MacDonald waveform (or similar drive algorithm) is used to drive the phases of the motor, less power may be required during disk spin-up because the MOSFETs that are on more (e.g., the low-side MOSFETs with a MacDonald waveform) may be sized larger than the MOSFETs that are on less (e.g., the high-side MOSFETs). In this manner, less power is dissipated in the larger size MOSFETs that are on more than the others.

    Abstract: A selective wet etching process is used, prior to air gap opening formation, to remove a sacrificial nitride layer from over a first region of an interconnect dielectric material containing a plurality of first conductive metal structures utilizing a titanium nitride hard mask portion located over a second region of the interconnect dielectric material as an etch mask. The titanium nitride hard mask portion located over the second region of the interconnect dielectric material is thereafter removed, again prior to air gap opening formation, utilizing another wet etch process. The wet etching processes are used instead of reactive ion etching.

    Abstract: A static induction transistor is formed on a silicon carbide substrate doped with a first conductivity type. First recessed regions in a top surface of the silicon carbide substrate are filled with epitaxially grown gate regions in situ doped with a second conductivity type. Epitaxially grown channel regions in situ doped with the first conductivity type are positioned between adjacent epitaxial gate regions. Epitaxially grown source regions in situ doped with the first conductivity type are positioned on the epitaxial channel regions. The bottom surface of the silicon carbide substrate includes second recessed regions vertically aligned with the channel regions and silicided to support formation of the drain contact. The top surfaces of the source regions are silicided to support formation of the source contact. A gate lead is epitaxially grown and electrically coupled to the gate regions, with the gate lead silicided to support formation of the gate contact.
