    摘要： Tools for conditioning chemical mechanical planarization (CMP) pads comprise a substrate with abrasive particles coupled to at least one surface. The tools can have various particle and bond configurations. For instance, abrasive particles may be bonded (e.g., brazed or other metal bond technique) to one side, or to front and back sides. Alternatively, abrasive particles are bonded to a front side, and filler particles coupled to a back side. The abrasive particles can form a pattern (e.g., hexagonal) and have particle sizes that are sufficiently small to penetrate pores of a CMP pad during conditioning, leading to fewer defects on wafers polished with the conditioned CMP pad. Grain bonding can be accomplished using brazing films, although other metal bonds may be used as well. Also, balanced bond material (e.g., braze on both sides) allows for low out-of-flatness value.

    摘要翻译： 用于调理化学机械平面化（CMP）衬垫的工具包括具有与至少一个表面耦合的磨料颗粒的衬底。 这些工具可以具有各种粒子和键结构。 例如，磨料颗粒可以结合（例如钎焊或其他金属粘合技术）到一侧或前后两侧。 或者，磨料颗粒结合到前侧，并且填料颗粒连接到背面。 研磨颗粒可以形成图案（例如六边形），并且具有足够小的粒度以在调理期间穿透CMP垫的孔，导致用经调节的CMP垫抛光的晶片上的缺陷较少。 可以使用钎焊膜来实现晶粒结合，尽管也可以使用其它金属键。 此外，平衡粘合材料（例如，两侧上钎焊）允许低的平坦度值。

    摘要： A study of several key conditioner design parameters has been conducted. The purpose was to improve conditioner performance by considering factors such as wafer defects, pad life, and conditioner life. For this study, several key conditioner design parameters such as diamond type, diamond size, diamond shape, diamond concentration and distribution, were selected to determine their effect on CMP performance and process stability. Experimental validations were conducted. Conditioner specifications were matched to each specific CMP environment (intended application) in order to improve process stability and CMP performance particularly for emerging technology nodes. Several conditioner designs were developed and run successfully in the field. Significant planarity improvement for a 300 mm CMP process was achieved in accordance with one embodiment, and an increase of pad life and wafer polish rate was simultaneously achieved with another embodiment.

    摘要： Abrasive tools and techniques are disclosed that can cut hard, brittle materials to relatively precise dimensions. The tools, which can include a hybrid bond of metal or metal alloy and a resin matrix together with fine abrasive grits, can be employed, for example, in mirror finish cutting applications, thereby enabling ‘1×’ or ‘single-pass’ multi-function abrasive processes. The specific selection of resin and metal or metal alloy types is such that the tool is sufficiently brittle for the purpose of manufacture and durability, but ductile enough to withstand the grinding and handling stresses (an exemplary hybrid bond includes bronze and polyimide). Numerous tool types and applications will be apparent in light of this disclosure, including abrasive products for electronic device manufacturing such as thin 1A8 blades (single blade or multi-blade configuration).
