    摘要: The present invention provides a prebent ceramic suspension which includes a ceramic load beam which is bent by a stress patch. With thin film techniques the stress patch is formed on top of the load beam. In the preferred embodiment the patch is amorphous hydrogenated diamond-like carbon. When the suspension is on a wafer the carbon patch exerts a compressive stress on a top surface of the load beam just under the patch. When the suspension is released from the wafer the compressive patch exerts tensile forces on the top surface of the load beam causing an end of the load beam to bend toward the wafer. The amount of bending of the suspension can be accurately controlled by the cross sections of the load beam and the patch as well as the lateral dimensions of the patch. Further control can be achieved by controlling the hydrogen, nitrogen and other additive components of the carbon patch. After fabrication bending can be lessened by machining portions of the patch with a laser beam to effectively negate the stress of these portions. Still further, the patch can be laterally configured so that the suspension forms an arc when preloaded on a disk. During fabrication various layers can be formed by thin film deposition to form an integrated magnetic head-slider-suspension. A pair of prebent ceramic suspensions can be preloaded on adjacent magnetic disks by a single actuator arm.

    摘要: An amorphous fluorinated carbon film for use as a dielectric insulating layer in electrical devices is formed from a fluorinated cyclic hydrocarbon precursor. The precursor may be selected from the group consisting of hexafluorobenzene, 1,2-diethynyltetrafluorobenzene and 1,4-bis(trifluoromethyl) benzene. The film is deposited by a radiation or beam assisted deposition technique such as an ion beam assisted deposition method, a laser assisted deposition method, or a plasma assisted chemical vapor deposition method. The film is thermally stable in non-oxidizing environment at temperatures up to 400° C. and has a low dielectric constant of less than 3.0. The film can be suitably used as an insulator for spacing apart conductors in an interconnect structure.

    摘要: A method for treating a film of carbon-based dielectric material such as diamond-like carbon to remove volatiles is described. The method incorporates the steps of providing a non-oxidizing ambient and heating the film above 350.degree. C. Heating may be by rapid thermal annealing. The dielectric constant of the material may be lowered. A stabilized carbon-based material is provided with less than 0.5% thickness or weight change/hour at a selected temperature at or below 400.degree. C. The invention overcomes the problem of dimensional instability during the incorporation of the material in integrated circuit chips as an intra and inter level dielectric.

    摘要: A method for fabricating a thermally stable carbon-based low dielectric constant film such as a hydrogenated amorphous carbon film or a diamond-like carbon film in a parallel plate chemical vapor deposition process utilizing plasma enhanced chemical vapor deposition process is disclosed. Electronic devices containing insulating layers of thermally stable carbon-based low dielectric constant materials that are prepared by the method are further disclosed. In order to render the carbon-based low dielectric constant film thermally stable, i.e., at a temperature of at least 400.degree. C., the films are heat treated at a temperature of not less than 350.degree. C. for at least 0.5 hour. To enable the fabrication of thermally stable carbon-based low dielectric constant film, specific precursor materials such as cyclic hydrocarbons should be used, for instance, cyclohexane or benzene. The geometry of the chemical vapor deposition chamber is important in making the present invention thermally stable low dielectric constant films in order to achieve a specific bias voltage on the substrate onto which the electronic structure is formed.
