  • Patent number: 8192087
    Abstract: A fluid dynamic bearing formed by a microelectromechanical systems (MEMS) wafer-level batch-fabrication process is provided. The process results in a high performance and high reliability fluid dynamic bearing having features including higher bearing lifetime at high RPM, improved bearing stiffness, durability and thrust/restoring forces capabilities. The present invention is especially useful with small form factor disc drive memory devices having constraints in motor height, such as a 2.5 inch disc drive, requiring high performance including high rotational speed and large areal density. A sacrificial layer is utilized in the process to simultaneously form symmetrical facing surfaces of relatively rotatable components. The facing surfaces define, therebetween, a desired feature, such as a journal bearing, a thrust bearing, a fluid channel, a fluid reservoir, a capillary seal, pressure generating grooves, and other profile geometries.

  • Patent number: 7277257
    Abstract: A transducer-level microactuator selectively positions a transducer portion of a slider radially with respect to circumferential data tracks of a rotatable disc. The slider includes a slider body having a leading edge and a trailing edge, a transducer body and a flexure body. The transducer body is spaced from the trailing edge of the sliding body and includes at least one transducer element. The flexure body extends from the trailing edge of the slider body and includes a first anchor point connected to the slider body and a second anchor point connected to the transducer body. The basecoat layer is deposited on the trailing edge of the slider body and substantially surrounds the flexure body wherein a gap separates the flexure body from the basecoat. A first actuation assembly is formed on the basecoat and a second actuation assembly is formed on the transducer body adjacent the slider body.

  • Patent number: 7254885
    Abstract: A method is used for fabricating sliders for use in a disc drive actuation system, the sliders having bonds pads formed on either a top surface or side faces of the slider. The method comprises providing a substrate having a top surface. Trenches are formed in the substrate and filled with a bond pad material to form slider bond pads. Excess bond pad material is removed from the trenches such that the slider bond pads are flush with the top surface of the substrate. A transducer is fabricated on the top surface of the substrate. Finally, the slider bond pads are exposed.

  • Patent number: 6989493
    Abstract: An electrical feedthrough assembly for establishing an electrical connection path through an aperture in a side wall of a housing, and a method of fabrication thereof. The feedthrough assembly comprises a plate and at least one electrical contact which extends through the plate. Preferably, a heating member is further provided to extend along a circumference of the plate. The plate is sized to span and surround the aperture so that, upon generation of heat by the heating member, at least one ring of sealing material adjacent the heating member flows to establish a seal between the plate and the housing wall surrounding the aperture. The heat is preferably generated by applying current to the heating member. The feedthrough assembly is preferably fabricated using a microfabrication process. A batch fabrication operation is preferably employed so that a population of the plates are formed from a single panel and subsequently separated therefrom.

  • Patent number: 6785086
    Abstract: A slider for carrying and finely adjusting both a radial position and a flying height of a transducing head with respect to a track of a rotatable disc includes a stator portion carried by a support structure such as a flexure of a disc drive system. A plurality of springs extend from the stator portion and are flexible in a lateral direction (for radial positioning) and in a vertical direction (for flying height control). A rotor portion is connected to the stator portion by the plurality of springs. The rotor portion carries the transducing head. The stator portion includes a plurality of stator electrodes, and the rotor portion includes a plurality of rotor electrodes suspended between the stator electrodes. Selected voltages are applied to the stator electrodes and the rotor electrodes to create a selected force in the lateral and vertical directions for moving the rotor portion with respect to the stator portion to finely adjust the radial position and flying height of the transducing head.

  • Patent number: 6733681
    Abstract: A method of handling a wafer for through-wafer plasma etching includes lateral support provided between a handle wafer and a product wafer without wafer bonding or an adhesive film using mating mechanical structures. The product wafer is easily separated from the handle wafer following etching without stripping or cleaning. Because the connection between the wafers is mechanical, not from an adhesive layer/bonded layer, a wafer can be etched, inspected, and subsequently continue to be etched without the hindrance of repeated bonding, separation, and cleaning. A non-bonded support for released devices following a through-etch process is also provided.
