Abstract:
A method of providing a CMOS-MEMS structure is disclosed. The method comprises patterning a first top metal on a MEMS actuator substrate and a second top metal on a CMOS substrate. Each of the MEMS actuator substrate and the CMOS substrate include an oxide layer thereon. The method includes etching each of the oxide layers on the MEMS actuator substrate and the base substrate, utilizing a first bonding step to bond the first patterned top metal of the MEMS actuator substrate to the second patterned top metal of the base substrate. Finally the method includes etching an actuator layer into the MEMS actuator substrate and utilizing a second bonding step to bond the MEMS actuator substrate to a MEMS handle substrate.
Abstract:
Es wird ein Verfahren zur Herstellung eines mikromechanischen Bauelements vorgeschlagen, wobei eine Trenchstruktur im wesentlichen vollständig von einer ersten Auffüllschicht aufgefüllt und eine erste Maskenschicht auf der ersten Auffüllschicht aufgetragen wird, auf der wiederum eine zweite Auffüllschicht und eine zweite Maskenschicht aufgetragen werden. Weiterhin wird ein mikromechanisches Bauelement vorgeschlagen, wobei die erste Auffüllschicht die Trenchstruktur des mikromechanischen Bauelements auffüllt und gleichzeitig eine bewegliche Sensorstruktur bildet.
Abstract:
Some embodiments of the present invention provide processes and apparatus for electrochemically fabricating multilayer structures (e.g. mesoscale or microscale structures) with improved endpoint detection and parallelism maintenance for materials (e.g. layers) that are planarized during the electrochemical fabrication process. Some methods involve the use of a fixture during planarization that ensures that planarized planes of material are parallel to other deposited planes within a given tolerance. Some methods involve the use of an endpoint detection fixture that ensures precise heights of deposited materials relative to an initial surface of a substrate, relative to a first deposited layer, or relative to some other layer formed during the fabrication process. In some embodiments planarization may occur via lapping while other embodiments may use a diamond fly cutting machine.

PROBLEM TO BE SOLVED: To form a multi-layer three-dimensional structure by electrodepositing both of a structural material and a sacrificial material on a substrate. SOLUTION: This method for manufacturing the multi-layer three-dimensional structure comprises the steps of: bringing the substrate 2 to be plated into contact with a first article 4a which includes a mask 6 and a support 8; depositing a first metal 12 (for instance, a sacrificial metal) on the substrate in the presence of a first metal ion source; bringing the substrate 2 into contact with a second article 14 which includes a mask 16 and a support 18; depositing a second metal 20 (for instance, a structural metal) on the substrate in the presence of a second metal ion source; planarizing the layer; and repeating the above method by using electroplating articles 4a, 4b, 14a and 14b, which have a different pattern, to produce a multi-layered structure 24. An element 26 is obtained by etching all of the sacrificial metals 12. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
Microelectromechanical systems (MEMS) switches are described. The MEMS switches can be actively opened and closed. The switch can include a beam coupled to an anchor on a substrate by one or more hinges. The beam, the hinges and the anchor may be made of the same material in some configurations. The switch can include electrodes, disposed on a surface of the substrate, for electrically controlling the orientation of the beam. The hinges may be thinner than the beam, resulting in the hinges being more flexible than the beam. In some configurations, the hinges are located within an opening in the beam. The hinges may extend in the same direction of the axis of rotation of the beam and/or in a direction perpendicular to the axis of rotation of the beam.
