摘要: A polishing slurry includes liquid medium and particulate abrasive. The particulate abrasive includes soft abrasive particles, hard abrasive particles, and colloidal silica particles, wherein the soft abrasive particles have a Mohs hardness of not greater than 8 and the hard abrasive particles have a Mohs hardness of not less than 8, and wherein the soft abrasive particles and the hard abrasive particles are present at a weight ratio of not less than 2:1.

摘要: A method for chemical mechanical polishing of a substrate includes polishing the substrate at a stock removal rate of greater than about 2.5 Å/min to achieve a Ra of not greater than about 5.0 Å. The substrate can be a III-V substrate or a SiC substrate. The polishing utilizes a chemical mechanical polishing slurry comprising ultra-dispersed diamonds and at least 80 wt % water.
摘要翻译: 用于基材的化学机械抛光的方法包括以大于约2.5 /分钟的原料去除速率抛光基材以达到Ra不大于约。 衬底可以是III-V衬底或SiC衬底。 抛光使用包含超分散金刚石和至少80重量%水的化学机械抛光浆料。
