    Abstract: Micro-electromechanical systems (MEMS) pre-fabrication products and methods for forming MEMS devices using silicon-on-metal (SOM) wafers. An embodiment of a method may include the steps of bonding a patterned SOM wafer to a cover wafer (46), thinning the handle layer of the SOM wafer (48), selectively removing the exposed metal layer (50), and either continuing with final metallization (64) or cover bonding to the back of the active layer (62).

    Abstract: A non-volatile memory device and method of manufacturing a non-volatile micro-electromechanical memory cell. The method comprises the first step of depositing a first layer of sacrificial material on a substrate by use of Atomic Layer Deposition The second step of the method is providing a cantilever (101) over at least a portion of the first layer of sacrificial material. The third step is depositing, by use of Atomic Layer Deposition, a second layer of sacrificial material over the first layer of sacrificial material and over a portion of the cantilever such that a portion of the cantilever is surrounded by sacrificial material. The fourth step is providing a further layer material (107) which covers at least a portion of the second layer of sacrificial material. Finally, the last step is etching away the sacrificial material surrounding the cantilever, thereby defining a cavity (102) in which the cantilever is suspended.

    Abstract: Die Erfindung betrifft Mikro-Elektromechanische Elemente, die vielfältig mit geringfügigen Modifikationen in der Mikromechanik, -optik und auch -fluidik eingesetzt werden können. Sie sollen kostengünstig hergestellt werden können und für verschiedene Applikationen anpassbar sein. Die erfindungsgemäßen Elemente sind dabei so ausgebildet, dass auf einem Substrat eine elastisch verformbare Membran aus einem zumindest bereichsweise elektrisch leitenden Werkstoff so befestigt ist, dass zwischen Substrat und Membran ein Hohlraum oder ein Spaltbereich mittels Abstandshaltern ausgebildet ist. Ein oder mehrere Abstandshalter sind aus einem dielektrischen polymeren Werkstoff gebildet. Am Substrat ist mindestens ein Kontaktelement vorhanden, das an eine elektrische Spannungsquelle angeschlossen ist.

    Abstract: The fabrication of a MEMS device such as an interferometric modulator is improved by employing an etch stop layer (44) between a sacrificial layer (46) and a mirror layer (38). The etch stop may reduce undesirable over-etching of the sacrificial layer and the mirror layer. The etch stop layer may also serve as a barrier layer, buffer layer, and/or template layer.

    Abstract: The current invention provides for encapsulated release structures, intermediates thereof and methods for their fabrication. The multi-layer structure has a capping layer (211) that preferably comprises silicon oxide and/or silicon nitride and which is formed over an etch resistant substrate (203). A patterned device layer (206), preferably comprising silicon nitride, is embedded in a sacrificial material (205, 209), preferably comprising polysilicon, and is disposed between the etch resistant substrate (203) and the capping layer (211). Access trenches or holes (219) are formed into the capping layer (211) and the sacrificial material (205, 209) is selectively etched through the access trenches (219) such that portions of the device layer (206) are released from the sacrificial material (205, 209). The etchant preferably comprises a noble gas fluoride NgF2x (wherein Ng = Xe, Kr or Ar: and where x = 1, 2 or 3). After etching that sacrificial material (205, 209), the access trenches (219) are sealed to encapsulate (241) released portions the device layer (206) between the etch resistant substrate (203) and the capping layer (211). The current invention is particularly useful for fabricating MEMs devices, multiple cavity devices and devices with multiple release features.
