    摘要: CMP slurries for oxide film and a method for forming a metal line contact plug of a semiconductor device are described herein. When a polishing process of a multi-layer film is performed by using the disclosed CMP slurry for oxide film including an HXOn compound (wherein n is an integer from 1 to 4), a stable landing plug poly can be formed by preventing step differences by reducing interlayer polishing speed differences.

    摘要: Disclosed is a method for detecting an end-point of a CMP process of a semiconductor device. More specifically, when all polishing processes are performed using a nitride film as a polishing barrier film, a buffer layer including nitrogen is formed on the nitride film and a polishing process is performed. Then, the concentration of NO from ammonia gas generated from the buffer layer is detected so that the nitride film may be polished to a desired target without damage of the nitride film. As a result, an end-point can be set.

    摘要: A process for forming a copper wiring and the prevention of copper ion migration in a semiconductor device is disclosed herein. The process includes conducting a post-cleaning process for a copper layer that is to form the cooper wiring after already having undergone a CMP process. The post-cleaning process includes conducting a primary chemical cleaning using a citric acid-based chemical. A secondary chemical cleaning is then conducted on the copper layer having undergone the primary chemical cleaning using an ascorbic acid-based chemical. After the post-cleaning process is completed, the migration of copper ions over time is prevented thereby improving the reliability of the semiconductor device.

    摘要: In a method for planarizing an insulation layer in a semiconductor device, an insulation layer is formed over a semiconductor substrate having a cell region and a peripheral region. The cell region is higher than the peripheral region due to a capacitor formed in the cell region. A metal layer is formed over the insulation layer. The metal layer is chemical mechanical polished to expose the insulation layer portion in the cell region. The exposed insulation layer portion in the cell region is chemical mechanical polishing to planarize the insulation layer, and the planarized insulation layer and the remaining metal layer are chemical mechanical polishing to remove the metal layer remained in the peripheral region. The method for planarizing an insulation layer does not require a separate photosensitive layer forming process or a dry etching process.
