    Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of introducing energetic particles (22) in a selected manner through a surface of a donor substrate (10) to form a pattern at a selected depth (20) underneath the surface. The particles have a concentration sufficiently high to define a donor substrate material (12) above the selected depth. An energy source is directed to a selected region of the donor substrate to initiate a controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving action provides an expanding cleave front to free the donor material from a remaining portion of the donor substrate.

    Abstract: The present invention relates to a method for producing a multi-component wafer, in particular a MEMS wafer. The method according to the invention comprises at least the following steps: providing a bonding wafer (2), wherein at least one surface portion (4) of the bonding wafer (2) is formed by an oxide film, providing a dispenser wafer (6), wherein the dispenser wafer (6) is thicker than the bonding wafer (2), bringing the dispenser wafer (6) into contact with the surface portion (4) of the bonding wafer (2) that is formed by the oxide film, forming a multilayer arrangement (8) by connecting the dispenser wafer (6) and the bonding wafer (2) in the region of the contact, producing modifications (18) in the interior of the dispenser wafer (6) for predefining a detachment region (11) for separating the multilayer arrangement (8) into a detaching part (14) and a connecting part (16), wherein the production of the modifications (18) takes place before the formation of the multilayer arrangement (8) or after the formation of the multilayer arrangement (8), separating the multilayer arrangement along the detachment region as a result of a weakening of the multilayer arrangement brought about by the production of a sufficient number of modifications or as a result of production of mechanical stresses in the multilayer arrangement, wherein the connecting part (16) remains on the bonding wafer (2) and wherein the split-off detachment part (14) has a greater thickness than the connecting part (16).

    Abstract: A monolithically integrated MEMS pressure sensor and CMOS substrate using IC-Foundry compatible processes. The CMOS substrate is completed first using standard IC processes. A diaphragm is then added on top of the CMOS. In one embodiment, the diaphragm is made of deposited thin films with stress relief corrugated structure. In another embodiment, the diaphragm is made of a single crystal silicon material that is layer transferred to the CMOS substrate. In an embodiment, the integrated pressure sensor is encapsulated by a thick insulating layer at the wafer level. The monolithically integrated pressure sensor that adopts IC foundry-compatible processes yields the highest performance, smallest form factor, and lowest cost.

    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.
