项目摘要

Using ultra-high polishing pressure and polishing speed, this research aims to develop the double side surface polishing method of ultra-high removal rate for various kinds of workpieces such as magnet disk substrate, silicon wafer and so on. The new type of double side surface polishing machine based on new concept is manufactured on trial. In the machine, the workpiece is rotated by the couple of the friction forces in the reverse directions to each other, which are caused from the contact between workpiece and upper or lower polishing plate. That is, in the rotation mechanism of workpiece, the gear is not used. On the contrary, in the conventional polishing machine, the rotation of workpiece is done with the gear cut on the outside circle of carrier holding the disk substrate. Furthermore the double side surface polishing characteristics in the conditions of ultra-high polishing pressure and polishing speed using the new type of machine is examined. The summary is as follows ;1) Imp … More rovement of polishing machine(1) Establishment of stable rotation technique of workpieceFirst of all, the couple of friction forces is caused by stepping the polishing plate. In the method, to machine the plate the precise seep is difficult. And also the stable rotation of workpiece is obtained difficult. To resolve the problem, the new technique in which the contact friction force between the workpiece and polisher is changed by holing a part of the polisher (surface is developed. Using the method, the stable rotation of workpiece is done.(2) Development of cooling system of polisherIn the polishing conditions of ultra-high pressure and speed, large polishing heat occurs. Due to the heat, polisher surface is damaged. To solve the problem, the cooling systems of polishing plate are developed. The method is useful for the remove of generated heat.(3) Investigation of dynamic pressure on polishing characteristicsIn the condition ultra-high polishing speed, large buoyancy is found to reduce polishing pressure. On the basis of the result, the relationship between removal rate and polishing condition is cleared experimentally.2) Development of linear type of double surface polishing machineA linear type of double surface polishing machine in which the workpiece is rotated by the couple of friction forces as mentioned above for the rotary type of new double surface polishing machine is manufactured on trial. The machine is ascertained possible to perform the effective polishing operation.3) Investigation of polishing characteristics using the new type of double side surface polishing machineTo clear the polishing characteristics using the new type of polishing machine, the experiment is carried out by the various kinds of polishing conditions. The influence of polishing conditions on the removal rate and smoothness is cleared experimentally. Less
本研究旨在利用超高抛光压力和抛光速度,开发磁盘基片、硅片等多种工件的超高去除率双面抛光方法,试制基于新概念的新型双面抛光机。在机器中,工件在工件与上抛光板或下抛光板接触产生的相互相反方向的摩擦力的作用下旋转。也就是说,在工件的旋转机构中,不使用齿轮。相反,在传统的抛光机中,工件的旋转是通过在保持盘基板的载体的外圆上切割齿轮来完成的。并对新型抛光机在超高抛光压力和超高抛光速度条件下的双面抛光特性进行了研究。总结如下:1)Imp ...更多信息 抛光机的改进(1)工件稳定旋转技术的建立首先,抛光板的步进运动产生摩擦力偶。在该方法中,要加工出精确的渗液是一个难点。而且工件的稳定旋转也很难获得。为了解决这一问题,开发了一种新技术,即通过在抛光机的一部分(表面)上开孔来改变工件与抛光机之间的接触摩擦力。利用该方法实现了工件的稳定旋转。(2)抛光机冷却系统的研制在超高压、超高速的抛光条件下,会产生大量的抛光热。由于高温,抛光机表面受损。为解决这一问题,研制了抛光板冷却系统。该方法可用于去除产生的热量。(3)动压力对抛光特性的影响研究在超高抛光速度下,大浮力可以降低抛光压力。在此基础上,通过实验研究,明确了去除率与抛光条件的关系。2)直线型双面抛光机的研制试制了一台直线型双面抛光机,该抛光机中工件通过上述新型旋转式双面抛光机的摩擦力对旋转。3)新型双面抛光机的抛光特性研究为了明确新型抛光机的抛光特性,在各种抛光条件下进行了实验研究。实验研究了抛光条件对去除率和光滑度的影响。少
