Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain sterically hindered amine salt compounds. Dyed products and articles are effectively stabilized against color degradation. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.
摘要:
Methods and associated structures of forming a microelectronic device are described. Those methods may comprise forming a thin metal-organic layer on a copper structure, wherein the thin metal-organic layer substantially prevents corrosion of the copper structure, and wherein the thin metal-organic layer comprises an organo-copper compound comprising an alkyl group and a thiol group. In addition, methods of applying a high pH cleaning process using a surfactant to improve surface wetting in a low foaming solution is described.
摘要:
A method for cleaning a semiconductor wafer according to the present invention includes the steps of: removing particles on a semiconductor wafer with an alkaline chemical solution to clean the wafer; neutralizing a surface charge of the semiconductor wafer with a weak acid cleaning solution; and removing residual metal impurities on the semiconductor wafer with an acid chemical solution to clean the wafer. The surface of the semiconductor wafer is neutralized and the HPM treatment is then performed with the semiconductor wafer having no charge. As a result, the surface of the semiconductor wafer can be made extremely clean without attaching metal impurities thereto.

A cleaning solution and cleaning method are provided which: (1) make treatment at room temperature possible, and do not require heating, (2) use little chemicals and water, (3) do not require specialized apparatuses, and moreover, (4) do not require the use of specialized chemicals. The cleaning solution of the present invention comprises pure water containing 20 ppb-100 ppb of oxygen and 2 ppb or more of nitrogen. Furthermore, the cleaning solution may comprise electrolytically ionized water containing OH.sup.- and containing 20 ppb-100 ppb of oxygen. In the cleaning method of the present invention, the cleaning of a material to be cleaned is conducted in a cleaning solution comprising pure water containing 20 ppb-100 ppb of oxygen and 2 ppb-15 ppm of nitrogen, while applying ultrasound having a frequency of 30 kHz or more. Furthermore, in the cleaning method of the present invention, the cleaning of a material to be cleaned may be conducted in a cleaning solution comprising electrolytically ionized water containing OH.sup.- and containing 20 ppb-100 ppb of oxygen, while applying ultrasound having a frequency of 30 kHz or more.
摘要:
A method for removing metallic and organic contaminations from a surface of a semiconductor wafer comprises cleaning the semiconductor wafer with a cleaning solution which contains a chlorine compound acting as an oxidant and which has a pH value in the range of 1 to 3. The cleaning solution has an oxidation-reduction potential in the range of 800 mV to 1200 mV when measured on the basis of a saturated calomel electrode at a temperature 25.degree. C.
