Abstract: The present invention relates to lithographic methods for forming a dual relief pattern in a substrate, and the application of such methods to fabricating multilevel interconnect structures in semiconductor chips by a Dual Damascene process in which dual relief cavities formed in a dielectric are filled with conductive material to form the wiring and via levels. The invention comprises a twice patterned single mask layer Dual Damascene process modified by the addition of an easy-to-integrate sidewall liner to protect organic interlevel and intralevel dielectrics from potential damage induced by photoresist stripping steps during lithographic rework. The invention further comprises a method for forming a dual pattern hard mask which may be used to form dual relief cavities for use in Dual Damascene processing, said dual pattern hard mask comprising a first set of one or more layers with a first pattern, and a second set of one or more layers with a second pattern.

Abstract: 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.

Abstract: 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.

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.

Abstract: Noble metal plating on a preexisting seed layer is used in the fabrication of electrodes for DRAM and FRAM. The plating may be spatially selective or nonselective. In the nonselective case, a blanket film is first plated and then patterned after deposition by spatially selective material removal. In the selective case, the plated deposits are either selectively grown in lithographically defined areas by a through-mask plating technique, or selectively grown as a conformal coating on the exposed regions of a preexisting electrode structure. A diamond-like carbon mask can be used in the plating process. A self-aligned process is disclosed for selectively coating insulators in a through-mask process.
