    摘要: Slurries for chemical mechanical polishing (CMP) are provided including a high planarity slurry and high selectivity ratio slurry. A high planarity slurry includes at least one kind of metal oxide abrasive particle and an anionic polymer passivation agent having a first concentration. A high selectivity ratio slurry includes at least one kind of the metal oxide abrasive particle, the passivation agent in a second concentration that is less than the first concentration of the passivation agent for the high planarity slurry, one of a quaternary amine and the salt thereof, and a pH control agent. The high selectivity ratio slurry has a pH in a range of about over an isoelectric point of a polishing target layer and less than an isoelectric point of a polishing stopper. In addition, a CMP method using the CMP slurries having high planarity and high selectivity ratio is provided.

    摘要: A test pattern and a method of controlling a CMP using the same are provided. The test pattern is disposed on a monitoring region of a semiconductor substrate having a main region and a monitoring region. The test pattern includes a planar region and a pattern region. The method comprises setting a correlation between a step difference of a test pattern and an etched thickness of a main pattern, then applying the CMP to a semiconductor substrate having the test pattern and the main pattern for a predetermined time. The step difference of the test pattern is measured and the etched thickness of the main pattern, which corresponds to the step difference of the test pattern, is determined from the correlation. A polishing time is corrected by comparing the determined etched thickness of the main pattern with a reference value, and the corrected polishing time is applied to a subsequent lot or subsequent substrate.

    摘要: A polishing slurry including an abrasive, deionized water, a pH controlling agent, and polyethylene imine, can control the removal rates of a silicon oxide layer and a silicon nitride layer which are simultaneously exposed during chemical mechanical polishing (CMP) of a conductive layer. A relative ratio of the removal rate of the silicon oxide layer to that of the silicon nitride layer can be controlled by controlling an amount of the choline derivative.
