    摘要: Metal nitride and metal oxynitride extrusions often form on metal suicides. These extrusions can cause short circuits and degrade processing yields. The present invention discloses a method of selectively removing such extrusions. In one embodiment, a novel wet etch comprising an oxidizing agent and a chelating agent selectively removes the extrusions from a wordline in a memory array. In another embodiment, the wet etch includes a base that adjusts the pH of the etch to selectively remove certain extrusions relative to other substances in the wordline. Accordingly, new metal silicide structures can be used to form novel wordlines and other types of integrated circuits.

    摘要: The present invention is directed to fabrication of a capacitor formed with a substantially concave shape and having optional folded or convoluted surfaces. The concave shape optimizes surface area within a small volume and thereby enables the capacitor to hold a significant charge so as to assist in increased miniaturization efforts in the microelectronic field. The capacitor is fabricated in microelectronic fashion consistent with a dense DRAM array. Methods of fabrication include stack building with storage nodes that extend above a semiconductor substrate surface.

    摘要: A method used during the formation of a semiconductor device comprises the steps of forming a polycrystalline silicon layer over a semiconductor substrate assembly and forming a silicon nitride layer over the polycrystalline silicon layer. A silicon dioxide layer is formed over the silicon nitride layer and the silicon dioxide and silicon nitride layers are patterned using a patterned mask having a width, thereby forming sidewalls in the two layers. The nitride and oxide layers are subjected to an oxygen plasma which treats the sidewalls and leaves a portion of the silicon nitride layer between the sidewalls untreated. The silicon dioxide and the untreated portion of the silicon nitride layer are removed thereby resulting in pillars of treated silicon nitride. Finally, the polycrystalline silicon is etched using the pillars as a mask. The patterned polycrystalline silicon layer thereby comprises features having widths narrower than the width of the original mask.

    摘要: A method for removing a plurality of dielectric films from a supporting substrate by providing a substrate with a second dielectric layer overlying a first dielectric layer, contacting the substrate at a first temperature with a first acid solution exhibiting a positive etch selectivity at the first temperature, and then contacting the substrate at a second temperature with a second acid solution exhibiting a positive etch selectivity at the second temperature. The first and second dielectric layers exhibit different etch rates in the first and second acid solutions. The first and second acid solutions may contain phosphoric acid. The first dielectric layer may be silicon nitride and the second dielectric layer may be silicon oxide. Under these conditions, the first temperature may be about 175° C. and the second temperature may be about 155° C.

    摘要: A method and apparatus is disclosed for sequential processing of integrated circuits, particularly for conductively passivating a contact pad with a material which resists formation of resistive oxides. In particular, a tank is divided into three compartments, each holding a different solution: a lower compartment and two upper compartments divided by a barrier, which extends across and partway down the tank. The solutions have different densities and therefore separate into different layers. In the illustrated embodiment, integrated circuits with patterned contact pads are passed through one of the upper compartments, in which oxide is removed from the contact pads. Continuing downward into the lower compartment and laterally beneath the barrier, a protective layer is selectively formed on the insulating layer surrounding the contact pads. As the integrated circuits are moved upwardly into the second upper compartment, a conducting monomer selectively forms on the contact pads prior to any exposure to air. The integrated circuits can then be transferred to an ozone chamber where polymerization results in a conductive passivation layer on the contact pad.
