    • A polishing pad formed from closed-cell elastomer foam includes a population of bubbles within the pad. As the pad wears due to polishing and the polishing surface recedes, the freshly formed polishing surface includes pores formed of the newly exposed bubbles. The pores receive and retain polishing slurry and aid in the chemical mechanical polishing process. Pad conditioning is not required because new pores are constantly being created at the pad surface as the surface recedes during polishing. The method for forming the polishing pad includes the injection of gas bubbles into the viscous elastomer material used to form the pad. Process conditions are chosen to maintain gas bubbles within the elastomer material during the curing and solidifying process steps.
    • 由闭孔弹性体泡沫形成的抛光垫包括垫内的气泡群。 当由于抛光而抛光垫磨损并且抛光表面后退时,新形成的抛光表面包括由新露出的气泡形成的孔。 孔隙接收和保留抛光浆料并有助于化学机械抛光过程。 不需要衬垫调节,因为在抛光期间表面后退时,在衬垫表面上不断产生新的孔。 用于形成抛光垫的方法包括将气泡注入用于形成垫的粘性弹性体材料中。 选择工艺条件以在固化和固化过程步骤期间保持弹性体材料内的气泡。
