  • Patent number: 9041128
    Abstract: A Micro-Electro-Mechanical System (MEMS). The MEMS includes a lower chamber with a wiring layer and an upper chamber which is connected to the lower chamber. A MEMS beam is suspended between the upper chamber and the lower chamber. A lid structure encloses the upper chamber, which is devoid of structures that interfere with a MEMS beam. The lid structure has a surface that is conformal to a sacrificial material vented from the upper chamber.

  • Patent number: 8921144
    Abstract: A method of forming at least one Micro-Electro-Mechanical System (MEMS) includes forming a lower sacrificial material used to form a lower cavity. The method further includes forming a cavity via connecting the lower cavity to an upper cavity. The cavity via is formed with a top view profile of rounded or chamfered edges. The method further includes forming an upper sacrificial material within and above the cavity via, which has a resultant surface based on the profile of the cavity via. The upper cavity is formed with a lid that is devoid of structures that would interfere with a MEMS beam, including: depositing a lid material on the resultant surface of the upper sacrificial material; and venting the upper sacrificial material to form the upper cavity such the lid material forms the lid which conforms with the resultant surface of the upper sacrificial material.

  • Patent number: 8865497
    Abstract: A method of forming at least one Micro-Electro-Mechanical System (MEMS) includes forming a lower wiring layer on a substrate. The method further includes forming a plurality of discrete wires from the lower wiring layer. The method further includes forming an electrode beam over the plurality of discrete wires. The at least one of the forming of the electrode beam and the plurality of discrete wires are formed with a layout which minimizes hillocks and triple points in subsequent silicon deposition.

  • Patent number: 6420263
    Abstract: A method of forming a semiconductor device having aluminum lines therein, wherein the occurrence of lateral extrusions and voids are reduced. The method comprises the formation of a metal stack on a surface of the substrate, wherein the aluminum layer of the metal stack is deposited under controlled conditions; etching the metal lines in the metal stack; and exposing the substrate to a subsequent anneal.

  • Patent number: 6339022
    Abstract: A method for increasing the production yield of semiconductor devices having copper metallurgy planarized by a chemical-mechanical planarization process which includes a slurry that contains a conductor passivating agent, like benzotriazole, wherein a non-oxidizing anneal is used to remove any residue which might interfere with mechanical probing of conductive lands on the substrate prior to further metallization steps. The anneal may be performed by any of several techniques including a vacuum chamber, a standard furnace or by rapid thermal annealing.
