    Abstract: A production method for chips, in which as many method steps as possible are carried out in the wafer composite, that is, in parallel for a plurality of chips disposed on a wafer. This is a method for producing a plurality of chips whose functionality is implemented on the basis of the surface layer of a substrate. In this method, the surface layer is patterned and at least one cavity is produced below the surface layer, so that the individual chip regions are connected to each other and/or to the rest of the substrate by suspension webs only, and/or so that the individual chip regions are connected to the substrate layer below the cavity via supporting elements in the region of the cavity. The suspension webs and/or supporting elements are cut when the chips are separated. The patterned and undercut surface layer of the substrate is embedded in a plastic mass before the chips are separated.

    Abstract: In a method for manufacturing a micromechanical chip, a sacrificial layer and an epitaxy layer are initially applied to a semiconductor substrate to produce a layer stack. An opening is subsequently introduced into the epitaxy layer from the front side of the layer stack. In order to electrically insulate the subsequent filling of the opening using a conductive contact layer from the material of the epitaxy layer, the walls of the opening are provided with an insulating layer. For removing the sacrificial layer and thus for producing the chip, separation trenches are subsequently etched through the epitaxy layer to the sacrificial layer also from the front side of the layer stack, which separation trenches also delimit the lateral extension of the chip.

    Abstract: A simple and economical method for manufacturing very thin capped MEMS components. In the method, a large number of MEMS units are produced on a component wafer. A capping wafer is then mounted on the component wafer, so that each MEMS unit is provided with a capping structure. Finally, the MEMS units capped in this way are separated to form MEMS components. A diaphragm layer is formed in a surface of the capping wafer by using a surface micromechanical method to produce at least one cavern underneath the diaphragm layer, support points being formed that connect the diaphragm layer to the substrate underneath the cavern. The capping wafer structured in this way is mounted on the component wafer in flip chip technology, so that the MEMS units of the component wafer are capped by the diaphragm layer. The support points are then cut through in order to remove the substrate.
