摘要:
The disclosure pertains to compositions and methods for modifying or refining the surface of a wafer suited for semiconductor fabrication. The compositions include working liquids useful in modifying a surface of a wafer suited for fabrication of a semiconductor device. In some embodiments, the working liquids are aqueous solutions of initial components substantially free of loose abrasive particles, the components including water, a surfactant, and a pH buffer exhibiting at least one pKa greater than 7. In certain embodiments, the pH buffer includes a basic pH adjusting agent and an acidic complexing agent, and the working liquid exhibits a pH from about 7 to about 12. In further embodiments, the disclosure provides a fixed abrasive article comprising a surfactant suitable for modifying the surface of a wafer, and a method of making the fixed abrasive article. Additional embodiments describe methods that may be used to modify a wafer surface.
摘要(中):
本公开涉及用于修改或精炼适合半导体制造的晶片表面的组合物和方法。 该组合物包括用于修饰适用于制造半导体器件的晶片表面的工作液体。 在一些实施方案中,工作液体是基本上不含松散磨料颗粒的初始组分的水溶液,所述组分包括水,表面活性剂和显示至少一个大于7的pKa的pH缓冲剂。在某些实施方案中,pH缓冲剂包含 碱性pH调节剂和酸性络合剂,并且工作液体显示约7至约12的pH。在其他实施方案中,本公开提供了包含适用于改性晶片表面的表面活性剂的固定磨料制品,以及方法 制造固定磨料制品。 另外的实施例描述了可用于修改晶片表面的方法。 p>
