Abstract: Embodiments of the present disclosure generally relate to polishing pads, and methods for manufacturing polishing pads, which may be used in a chemical mechanical polishing (CMP) process in the manufacture of semiconductor devices. The polishing pads described herein feature a continuous polymer phase of polishing pad material comprising one or more first material domains and a plurality of second material domains. The one or more first material domains are formed of a polymerized reaction product of a first pre-polymer composition, the plurality of second material domains are formed of a polymerized reaction product of a second pre-polymer composition, the second pre-polymer composition is different from the first pre-polymer composition, and interfacial regions between the one or more first material domains and the plurality of second material are formed of a co-polymerized reaction product of the first pre-polymer composition and the second pre-polymer composition.

Abstract: 本発明は、固定砥粒ワイヤを、複数の溝付ローラに巻きかけることによってワイヤ列を形成し、往復走行させながら、接合部材を介してワーク保持手段で保持したワークを、切り込み送りすることによって、ワークを複数の箇所で同時に切断するワークの切断方法であって、接合部材として、その一部が砥石であるものを用い、ワークの切断終了後、かつ、ワイヤ列からワークを引き抜く前に、砥石に押し付けて固定砥粒ワイヤを往復走行させ、固定砥粒ワイヤの固定砥粒を除去する固定砥粒除去工程を有し、固定砥粒除去工程における、ワイヤ速度が１００ｍ／ｍｉｎ．以下、かつ、荷重が固定砥粒ワイヤ１本当たり３０ｇ以上であることを特徴とするワークの切断方法である。これにより、ワーク切断後のワイヤの引き抜きにおいて、ワークにワイヤが引っ掛かってソーマークが生じたり、ワイヤの断線が発生したりすることがないワークの切断方法及びワイヤソーが提供される。

Abstract: Eine Schleifscheibe (1) umfasst eine Schleifschicht (2), die aus mittels eines Bindemittels (3) gebundenen Schleifkörnern (4) ausgebildet ist. An Außenseiten (5, 7) der Schleifschicht (2) sind Armierungsgewebe (6, 8) in die Schleifschicht (2) eingebettet. An mindestens einem der Armierungsgewebe (6, 8) ist mindestens ein zusätzliches Gewebe (W 1 bis W 4 ) angeordnet, das einen jeweiligen Durchmesser hat, der kleiner als der Durchmesser der Armierungsgewebe (6, 8) ist. Das mindestens eine zusätzliche Gewebe (W 1 bis W 4 ) versteift die Schleifscheibe (1) in einem Bereich um eine zentrale Öffnung (9) und verbessert die Eigenschaften der Schleifscheibe (1) beim Schruppen und/oder Trennen.

Abstract: A coated abrasive article comprises a backing having first and second opposed major surfaces. A make layer is bonded to the first major surface. Agglomerate grinding aid particles are directly bonded to the make layer. At least a portion of the agglomerate grinding aid particles comprise grinding aid particles retained in a binder, and are arranged according to an open predetermined pattern. Abrasive particles are directly bonded to the make layer in spaces between the agglomerate grinding aid particles. A size layer is directly bonded to the make layer, agglomerate grinding aid particles, and abrasive particles. A method of making a coated abrasive article, in which the agglomerate grinding aid particles are deposited onto a curable make layer precursor prior to depositing abrasive particles onto the curable make layer precursor in spaces between the agglomerate grinding aid particles is also disclosed.
