摘要:
A method and composition for removing copper-containing post-etch and/or post-ash residue from patterned microelectronic devices is described. The removal composition includes a diluent, a solvent and a copper corrosion inhibitor, wherein the diluent may be a dense fluid or a liquid solvent. The removal compositions effectively remove the copper-containing post-etch residue from the microelectronic device without damaging exposed low-k dielectric and metal interconnect materials.
摘要:
A method and composition for removing bulk and ion-implanted photoresist and/or post-etch residue material from densely patterned microelectronic devices is described. The composition includes a co-solvent, a chelating agent, optionally an ion pairing reagent, and optionally a surfactant. The composition may further include dense fluid. The compositions effectively remove the photoresist and/or post-etch residue material from the microelectronic device without substantially over-etching the underlying silicon-containing layer(s) and metallic interconnect materials.
摘要:
A continuous-flow supercritical fluid (SCF) apparatus and method for the deposition of thin films onto microelectronic devices or the removal of unwanted layers, particles and/or residues from microelectronic devices having same thereon. The SCF apparatus preferably includes a dynamic mixer to ensure homogeneous mixing of the SCF and other chemical components.

摘要:
A method and composition for removing hardened photoresist, post-etch photoresist, and/or bottom anti-reflective coating from a microelectronic device is described. The composition may include a dense fluid, e.g., a supercritical fluid, and a dense fluid concentrate including a co-solvent, optionally a fluoride source, and optionally an acid. The dense fluid compositions substantially remove the contaminating residue and/or layers from the microelectronic device prior to subsequent processing, thus improving the morphology, performance, reliability and yield of the microelectronic device.
摘要:
A removal composition and process for removing low-k dielectric material, etch stop material, and/or metal stack material from a rejected microelectronic device structure having same thereon. The removal composition includes hydrofluoric acid. The composition achieves at least partial removal of the material(s) from the surface of the microelectronic device structure having same thereon, for recycling and/or reuse of said structure, without damage to the underlying polysilicon or bare silicon layer employed in the semiconductor architecture.
