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.

摘要:
Real-time analysis of electrochemical deposition (ECD) metal plating solutions is described, for the purpose of reducing plating defects and achieving high quality metal deposition. Improved plating protocols are utilized for increasing potential signal strength and reducing the time required for each measurement cycle. New methods and algorithms for simultaneously determining concentrations of organic additives, inorganic additives, and/or byproducts in a sample ECD solution are described. In one aspect, a method is provided for simultaneously determining concentrations of all organic additives, inorganic additives, and/or byproducts within a single experimental run by using a single analytical cell, while interactions between such additives are properly accounted for.

A composition comprising a magnesium halide coated macroporous carbonaceous substrate is provided for effecting moisture removal from a hydrogen halide fluid. Moisture removal is effected by intimately contacting the hydrogen halide fluid with the magnesium halide coated macroporous carbonaceous substrate and separating the fluid from the coated substrate.

The present invention relates to a method and apparatus for determining organic additive concentrations in a sample electrolytic solution, preferably a copper electroplating solution, by measuring the double layer capacitance of a measuring electrode in such sample solution. Specifically, the present invention utilizes the correlation between double layer capacitance and the organic additive concentration for concentration mapping, based on the double layer capacitance measured for the sample electrolytic solution.
摘要:
A CMP composition containing 5-aminotetrazole, e.g., in combination with oxidizing agent, chelating agent, abrasive and solvent and a method of use. Such CMP composition may be diluted during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface during CMP processing.

The present invention relates to method and apparatus for determining concentrations of organic additives in metal plating solutions, based on infrared spectroscopy, and more specifically attenuated total reflection infrared spectroscopy (ATR-IR).

A novel bodysuit is provided. In particular, the present invention provides a bodysuit that presents a neat and kept appearance of a tucked-in shirt without the use of cumbersome elastic garters and loose magnetic attachments. The unique arrangement of the present bodysuit garment allows the user to engage in vigorous activities, such as horseback rodeo riding, while maintaining a kept appearance without dislodgement of fasteners or connectors through inadvertent contact with a saddle horn or other type of exterior object.
