Method and product for forming a dual damascene interconnect structure, wherein depositing a copper sulfide interface layer as sidewalls to the opening deters migration or diffusing of copper ions into the dielectric material.
摘要:
A method for forming dual-damascene type conducting interconnects with non-metallic barriers that protect said interconnects from fluorine out-diffusion from surrounding low-k, fluorinated dielectric materials. One embodiment of the method is particularly suited for forming such interconnects in microelectronics fabrications of the sub 0.15 micron generation.
摘要:
A system and method for forming a plurality of structures in a low dielectric constant layer is disclosed. The low dielectric constant layer is disposed on a semiconductor. The method and system include exposing the low dielectric constant layer to an agent that improves adhesion of a photoresist, providing a layer of the photoresist on the low dielectric constant layer, patterning the photoresist, and etching the low dielectric constant layer to form the plurality of structures.
摘要:
A method of forming a conductive cap layer over a metal bonding pad comprises the following steps. A semiconductor structure is provided having an exposed, recessed metal bonding pad within a layer opening. The layer has an upper surface. The exposed metal bonding pad is treated with a solution containing soluble metal ions to form a conductive cap over the metal bonding pad. The conductive cap layer is comprised of the solution metal and has a predetermined thickness. An external bonding element may then be bonded to the conductive cap, forming an electrical connection with the metal bonding pad.
摘要:
An inexpensive and safe copper removal method in the fabrication of integrated circuits is described. Copper is stripped or removed by a chemical mixture comprising an ammonium salt, an amine, and water. The rate of copper stripping can be controlled by varying the concentration of the ammonium salt component and the amount of water in the mixture. Also a novel chemical mixture for stripping copper and removing copper contamination is provided. The novel chemical mixture for removing or stripping copper comprises an ammonium salt, an amine, and water. For example, the novel chemical mixture may comprise ammonium fluoride, water, and ethylenediamine in a ratio of 1:1:1.
