    • The present invention relates to an environmentally-friendly slurry for shallow trench isolation (STI) process and an additive composition. The slurry composition including abrasive grains prepared using a liquid phase method of the present invention can show enhanced polishing properties such as enhanced universal selectivity, high polishing speed, washing function and the likes using small amount of polishing additive. By performing the polishing process using the polishing additive including hydrogen bond between oxygen in polyoxyethylene oxide (PEO) and hydrogen of carboxyl group in anionic polymer, the universal selectivity can be performed by applying high dilution ratio of complexation of the PEO and anionic polymer, and selection ratio for nitride membrane and poly film can be controlled. In addition, the present invention can be applied to poly film stop process and nitride membrane stop process.

    • The present invention relates to polishing slurry for removing an initial step and a method for polishing a substrate or a wafer using the same. The polishing slurry for removing initial step of the present invention has particles of which surface is dispersed to have a positive electric charge, has the high polishing speed of a silicon oxide film. When a polishing process is performed using polishing slurry for removing an initial step of the present invention, a high polishing speed is obtained in a high step area and a low polishing speed is obtained in a low step area, thereby being effective for removing an initial step in shallow trench isolation chemical mechanical polishing.

    • The present invention relates to an environmentally-friendly polishing slurry for a STI process and a polishing method for a substrate or wafer using the same. The polishing slurry in the present invention has a narrow and uniform particle size distribution using monocrystalline polishing particles and is capable of minimizing micro scratch, alleviating dishing compared to dispersion due to positive electrostatic repulsion between the monocrystalline polishing particles, and improving cleaning property after polishing. In addition, the polishing slurry can secure long-term stability by adding a dispersion stabilizing agent, has excellent polishing rate and selection ratio, and can secure environmentally-friendly characteristics by the formation of neutral pH.
    • 本发明涉及用于STI工艺的环境友好型抛光浆料和使用其的基板或晶片的抛光方法。 本发明的研磨浆料使用单晶抛光颗粒具有窄且均匀的粒度分布,并且能够使由于单晶抛光颗粒之间的正静电排斥而产生的与分散相比的微刮痕减轻凹陷,并提高抛光后的清洁性能。 此外,抛光浆料可以通过添加分散稳定剂来确保长期稳定性,具有优异的抛光速率和选择比,并且可以通过形成中性pH来确保环境友好的特性。
