  • Publication number: 20080096385
    Abstract: A method for manufacturing a semiconductor device with a slurry composition for forming a tungsten pattern. The method comprises: forming a trench in an insulating film formed on a substrate; depositing a tungsten film over the insulating film including the trench; first polishing a tungsten film with a first slurry for polishing metal to expose the insulating film, the polishing selectivity ratio of the first slurry onto tungsten/insulating film being range from 30 to 100; and second polishing the insulating film and the tungsten film with a second slurry, the polishing selectivity ratio of the second slurry onto insulating film/tungsten being range from 3 to 500. The method reduces a thickness difference of tungsten patterns, thereby improving a production yield of semiconductor devices.

  • Publication number: 20070045731
    Abstract: A flash memory device has a resistivity measurement pattern and method of forming the same. A trench is formed in an isolation film in a Self-Aligned Floating Gate (SAFG) scheme. The trench is buried to form a resistivity measurement floating gate. This allows the resistivity of the floating gate to be measured even in the SAFG scheme. Contacts for resistivity measurement are directly connected to the resistivity measurement floating gate. Therefore, variation in resistivity measurement values, which is incurred by the parasitic interface, can be reduced.

  • Publication number: 20050142811
    Abstract: A method for manufacturing a semiconductor device is disclosed. In a disclosed method, a high voltage device and a low voltage device are formed at the same time, before a thermal oxidization process for thickly forming a gate oxide film of a high voltage region, and a bonding structure on the surface of the oxide film in a high voltage region is broken by means of an ion implantation process. In growing the oxide film of an actual high voltage region, the oxide film of the high voltage region can be grown more rapidly than the growth rate by means of heat, thus reducing the bird's beak. Therefore, since a depletion region at the PN junction is increased, the CCST properties can be improved.
