  • Patent number: 6274025
    Abstract: A method to form a passivation layer over a MR Sensor so that the passivation layer defines the track width. The passivation layer is formed simultaneously with the development of the lift off structure in a novel developing/oxidizing solution that oxidizes the MR sensor and develops the photoresist. The passivation layer is an electrical insulator that prevents sensor current from shunting through the overspray of the leads and a heat conductor to allow MR heat to dissipate through the overspray. The method comprises: spinning-on and printing a lift-off photoresist structure over the MR sensor. Next, the lift-off photoresist structure is developed. The MR sensor is anodized in a developing/oxidizing solution to: (1) remove portions of the lower photoresist and (2) to form a (e.g., thin NiFeO) passivation layer on the MR layer at least partially under the upper photoresist layer. The passivation layer is etched to remove the passivation layer not covered by the lift-off structure.

An apparatus and method are disclosed for forming high aspect ratio microstructures (“HARMs”) on planar and non-planar surfaces, using a modification of the LIGA microfabrication process.

The polymer sheet is then pressed against, clamped to, or otherwise attached to a conductive substrate in such a way that the patterned holes in the sheet are not blocked. Subsequent electroplating produces well-defined HARM structures on the planar or non-planar surface, in shapes that are complementary to the lithographically patterned through-holes in the polymer.

  • Patent number: 6077410
    Abstract: Creating relatively pure and consistent crystals of high performance minerals, such as diamond, has long been pursued. Unfortunately, synthesizing crystals that exhibit deep bonding generally requires high temperatures and high pressures for the formation of large crystals. Alternatively, high pressure and explosive shock waves can also be utilized, as demonstrated by closed-bomb diamond synthesis. Diamond crystal formation at lower temperatures and pressures have been demonstrated, but the formations have been thin and inconsistent. A method of forming diamond and the synthesis of other high performance crystals that are consistent, and can be grown to larger sizes has not existed, nor has a means of providing uniform and consistent thin layers of diamond and other such crystals been demonstrated.

  • Patent number: 6022465
    Abstract: An apparatus and method for customizing electrode contact placement on a semiconductor wafer while depositing and/or removing a material on a semiconductor wafer. The present invention is a adapter having at least one opening through which at least one electrode contacts the semiconductor wafer. The adapter may be designed to have multiple openings at specified locations on the adapter, thus allowing multiple electrode contacts with the semiconductor wafer at pre-specified locations. A conductive sheet may couple with the adapter to carry an electrical current from an electrical conductor to the electrode contacts placed within the openings of the adapter.

  • Patent number: 5989406
    Abstract: A magnetically shape-anisotropic material is made by providing a matrix with a plurality of elongated holes, and depositing first and second magnetic materials in each hole so as to form elongated particles including the first material adjacent one end and the second material adjacent the opposite end. One of the materials is a magnetically soft material having relatively low coercivity whereas the other material is a magnetically hard material having relatively high coercivity. The particles have dimensions transverse to their axes of elongation smaller than the magnetic domain size of the magnetically soft material.

  • Patent number: 5985124
    Abstract: Disclosed is a nickel electroplating bath or a nickel alloy electroplating bath used for electroplating a conductor partially masked with an organic high-molecular resist layer, wherein the nickel electroplating bath contains a water-soluble nickel salt, and the nickel alloy electroplating bath contains both a water-soluble nickel salt and a water-soluble salt of a metal capable of being alloyed with nickel. The above electroplating bath is incorporated with an electrical conductive salt containing at least one cation selected from the group consisting of an ammonium ion, magnesium ion, calcium ion, aluminum ion, and barium ion. Further, the electrical conductive salt substantially does not contain a sodium ion and a potassium ion as cations. Such an electroplating bath is capable of electroplating a conductor partially masked with an organic high-molecular resist layer without floating of the resist layer.

  • Patent number: 5961807
    Abstract: A multipart seal is provided for electrically isolating from an electrolyte medium a projection secured at a projection base with a body surface, the projection and body surface having different electrochemical activities. A first seal part is a hollow cap sized and shaped to receive and cover the projection and to conform with the projection base. A second seal part is a cured, pliable sealant disposed on a cap wall about a cap opening and cap rim portion, and bonded with and covering the projection base and the body surface surrounding and immediately adjacent to the projection base. Both the first and second seal parts substantially will not react with or allow passage there through of the electrolyte medium. In an electrolytic method to coat the body surface, the projection is electrically isolated with the multipart seal prior to application of the electrolytic coating.

  • Patent number: 5956840
    Abstract: The invention relates to a method for producing low cost hermetic Integrated Module Assembly (IMA) packaging, where an aluminum coating (24) is deposited on a poly-tetrafluoral-ethaline substrate (20), the aluminum coating (24) is selectively etched to form a waveguide window (26) and the substrate (20) is selectively treated over the waveguide window (26) to produce a non-conductive hermetic seal. The substrate (20) is then joined to a metal carrier (28) containing the waveguide (30). As a result of using selectively treated low cost substrates to produce hermetic seals, more expensive substrates are not required to form hermetic seals over substrate to waveguide interconnections.

  • Patent number: 5911863
    Abstract: In a method of manufacturing foils of plastic material which are electrically conductive in a transverse direction, but not in the plane of the foil wherein micropassages are formed in the foil by etching nucleus traces which are generated by exposure to a heavy ion beam, conductive layers are deposited on one side of the foil and the micropassages are filled by electrolytic metal ion depositions from the other side until caps are formed on the passages. After dissolving the two conductive layers, the steps are repeated to form caps also on the passages at the other side of the foil so as to provide for good contacting capabilities at both sides of the foil.

  • Patent number: 5888371
    Abstract: An extremely small aperture is formed using a sharp conductive tip. The aperture may be in the form of a transparent window or an open aperture. In a first embodiment, the conductive tip is positioned adjacent a layer of titanium and a voltage is applied to the tip. The intense electric field near the tip anodizes the titanium and creates a small transparent window of titanium dioxide. In a second embodiment, a titanium layer is covered with a layer of silicon, a small region of the silicon is oxidized using a conductive tip, and the silicon and then the titanium are etched. In a third embodiment, an electric field from a conductive tip creates a pit in a surface titanium oxide layer. The titanium is then etched, using the oxide layer as a mask, to form an open aperture. The conductive tip is preferably the tip of an atomic force microscope.
