| 摘要 |
A micromechanical component and method for its manufacture, in particular an acceleration sensor or a rotational speed sensor, includes: function components suspended movably above a substrate; a first insulation layer provided above the substrate; a first micromechanical function layer including conductor regions provided above the first insulation layer; a second insulation layer provided above the conductor regions and above the first insulation layer; a third insulation layer provided above the second insulation layer; a second micromechanical function layer including first and second trenches provided above the third insulation layer, the second trenches extending to the third insulation layer above the conductor regions and the first trenches extending to a cavity beneath the movably suspended function components in the second micromechanical function layer.
