摘要： A method of CMP of a substrate surface includes providing a polishing pad having a polishing layer, that may be substantially free of abrasive particles, with a functional group chemically bonded (covalent or ionic) to the polishing layer. The functional group acts as an activator or catalyst for a compound of a polishing slurry to exhibit a higher material removal rate for removing selected portions of the surface of the substrate than exhibited in CMP of a substantially identical substrate in the presence of a substantially identical polishing slurry and a polishing pad wherein the substantially identical polishing layer does not have the functional group. The functional group may be derived from a compound comprising a polyamine, a polyelectrolyte, and/or an amino acid. A method of making the CMP pad and the CMP pad formed thereby is also disclosed.
摘要翻译：衬底表面的CMP的方法包括提供具有抛光层的抛光垫，抛光层可以基本上没有磨料颗粒，与抛光层化学键合（共价或离子）的官能团。官能团用作抛光浆料化合物的活化剂或催化剂，以在基本上相同的抛光剂存在下，显示更高的材料去除速率，以除去基材表面的选定部分，基本相同的基材CMP 浆料和抛光垫，其中基本相同的抛光层不具有官能团。官能团可以衍生自包含多胺，聚电解质和/或氨基酸的化合物。还公开了一种制造由此形成的CMP焊盘和CMP焊盘的方法。

摘要： Particular aspects provide a method for recovering phosphate, comprising: obtaining an effluent or wastewater, etc. having calcium-sequestered phosphate; adding to the effluent or wastewater a calcium chelating or sequestration agent suitable to chelate or sequester Ca++ ions from the calcium-sequestered phosphate to facilitate release of phosphate from the calcium-sequestered phosphate; transferring, facilitated by said Ca++ ion capture and in the presence of sufficient concentrations of NH4+ and Mg2 ions, of the phosphate into struvite (magnesium ammonium phosphate hexahydrate or MgNH4PO4.6H2O), or hydrated magnesium ammonium complex of phosphate; and recovering the struvite, or the formed hydrated magnesium ammonium complex. Preferably, the method further comprises acidification of the effluent or wastewater to facilitate release of Ca++ ions from the calcium-sequestered phosphate and chelation of sequestration of the Ca++ ions by the calcium chelating or sequestration agent. Additional aspects provide a phosphate-containing fertilizer comprising struvite, and methods for making same.
