  • Patent number: 10894935
    Abstract: Compositions for removing silicone resins and methods of thinning a substrate by using the same, as well as related methods, apparatus and systems for facilitating the removal of silicone resins are provided. The compositions for removing silicone resins, may include a heterocyclic solvent and an alkyl ammonium fluoride salt represented by a formula, (R)4N+F?, wherein R is a C1 to C4 linear alkyl group. Silicone resins may be effectively removed by using the compositions since the compositions exhibit an excellent decomposition rate with respect to the silicone resins that remain on a semiconductor substrate in a process of backside grinding of the semiconductor substrate, backside electrode formation, or the like.

  • Publication number: 20080026585
    Abstract: A film (e.g., silicon polymer film, photoresist film) may be removed by applying a composition including a quaternary ammonium hydroxide, a sulfoxide compound, a dialkylene glycol alkyl ether, and/or water to the film. A silicon polymer film (e.g., hard mask layer) and a photoresist film, for example, may be removed by the composition using an in-situ process. Additionally, the composition may remove the silicon polymer film and the photoresist film while preventing or reducing damage to an underlying layer and the generation of particle-type etch residue.

  • Publication number: 20060014391
    Abstract: A metal-containing pattern structure is formed on a semiconductor substrate, and a cleaning composition is applied to the semiconductor substrate. The cleaning composition includes, based on a total weight of the cleaning composition, about 78 wt % to about 99.98 wt % of an acidic aqueous solution, about 0.01 wt % to about 11 wt % of a first chelating agent, and about 0.01 wt % to about 11 wt % of a second chelating agent. The metal-containing pattern structure includes an exposed first surface portion and a second surface portion covered with a polymer. Application of the cleaning solution forms a first corrosion-inhibition layer on the first surface portion of the metal-containing pattern structure, and removes the polymer from the second surface portion of the metal-containing pattern structure.

  • Patent number: 6740169
    Abstract: A conditioning disk and a conditioner for a chemical mechanical polishing (CMP) pad, and a method of fabricating, reworking, and cleaning the conditioning disk, are utilized to improve conditioning efficiency, and to reduce production expenses. The conditioning disk for a CMP pad is divided into regions defined by a size difference of abrasive grains formed on the body surface in each region of the conditioning disk. The method of fabricating the conditioning disk is performed by forming adhesive films for attaching the abrasive grains onto the body surface multiple times. In addition, a used conditioning disk may be reworked by detaching the abrasive grains from the body, and attaching new abrasive grains. A used conditioning disk can also be cleaned of by-products of the conditioning process by a cleaning method using a HF solution or BOE (buffered oxide etch) solution.
