    摘要: 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.

    摘要: Disclosed is a chemical-mechanical polishing composition used in a process for chemical-mechanical polishing of silicon oxide layer having severe unevenness with large step-height. The composition includes abrasive particles of metal oxide; and at least one compound(s) selected from the group consisting of amino alcohols, hydroxycarboxylic acid having at least 3 of the total number of carboxylic acid group(s) and hydroxyl group(s) or their salts, or a mixture thereof. A polymeric organic acid, a preservative, a lubricant and a surfactant may be further contained. The composition shortens the vapor-deposition time of a layer to be polished, saves the raw material to be vapor-deposited, shortens the chemical-mechanical polishing time, and saves the slurry employed.

    摘要: The present invention relates to a novel slurry composition for copper polishing, comprising zeolite which is a porous crystalline material for CMP of copper film in a semiconductor manufacturing process. The slurry composition according to the present invention comprises zeolite, an oxidant and a polish promoting agent and may further comprise a corrosion inhibitor, a surfactant, an aminoalcohol, an antiseptic and a dispersion agent and pH is in a range of 1 to 7. The zeolite slurry according to the present invention has advantages of absorbing and removing metal cation generated in CMP process by using zeolite and having a low level of scratches as the zeolite has micropores therein and thus its hardness is low. The slurry composition using zeolite of the present invention is usable to both first and second step polishing of copper damascene process and particularly useful as the first step polishing slurry for copper.
