摘要： To prevent air from being trapped inside a bearing and causing the bearing to have oil film rupture and NRRO to deteriorate. In a hydrodynamic bearing, a first lubricant reservoir is provided in a gap between a lower surface of a hub and a sleeve, and a second lubricant reservoir is provided in a gap between an outer peripheral surface of the sleeve and an inner peripheral surface of the hub or an inner peripheral surface of a stopper member fixed to the hub. If air enters inside such a hydrodynamic bearing, the air has to be discharged. For this purpose, the relationship in widths of the radial bearing gap, the maximum gap of the first lubricant reservoir under the lower surface of the hub and the maximum gap of the second lubricant reservoir on the sleeve outer peripheral surface, or the relationship in magnitudes of capillary forces thereof is adjusted. The principle that air tends to move toward the portion having smaller capillary pressure is utilized to make it difficult for the air to be trapped inside the bearing and to smoothly discharge the air from a gas-liquid interface of the second lubricant reservoir.

摘要： A capacity layer is formed of non-doped polysilicon. Unlike capacity layers formed of an oxide film, generation of seams and the like can be suppressed and thereby a stable capacity layer can be formed. Moreover, polysilicon used as a capacity layer may be doped polysilicon, and an oxide film formed on the surface of the polysilicon also serves as a capacity film. Thus, provision of an insulated gate device featuring low capacity is made possible.

摘要： A Schottky barrier diode in which a p+-type semiconductor layer is provided in an n−-type epitaxial layer can realize lowering the forward voltage VF without considering leak current IR. However, when compared with a normal Schottky barrier diode, the forward voltage VF is generally high. When a Schottky metal layer is suitably selected, although the forward voltage VF can be reduced, there is a limit in further reduction. On the other hand, when the resistivity of the n−-type semiconductor layer is reduced, although the forward voltage VF can be realized, there is a problem that breakdown voltage is deteriorated. In a semiconductor device of the invention, a second n−-type semiconductor layer having a low resistivity is laminated on a first n−-type semiconductor layer capable of securing a specified breakdown voltage. P+-type semiconductor regions are made to have depths equal to or slightly deeper than the second n−-type semiconductor layer. By this, in a Schottky barrier diode in which leak current IR can be suppressed by pinch off of a depletion layer, the forward voltage VF can be reduced and the specified breakdown voltage can be secured.
