CMP slurries were filtered by porous membrane filters of various materials to investigate the effect of surface property on filterability. All the filtrates not depending on the membrane materials showed reduction of abrasive particle concentration followed by immediate recovery at filtration startup. A mechanism of the results would be (a) significant amount of adsorption of abrasive particles at startup, (b) restraint of capture of additional abrasive particles by repulsion between adsorbed particles and dispersed particles. The mechanism indicates that naked surface property of the membranes would have no effect on filterability; instead property of adsorbed abrasive particles would dominate whole filtration process. The adsorption of abrasive particles was found to cause a significant increase and deviation of initial delta P. Pretreatment of the membrane filters with capturing small amount of abrasive particles was effective to restrain the increase and deviation of initial delta P.

During Cu CMP, Cu surface is oxidized by an oxidizer or a complexiation reagent. To inhibit oxidation, a corrosion inhibitor is co-added in the slurry. Balancing oxidation and surface passivation is of importance in advanced Cu CMP. Layer formation onto clean Cu surfaces in BTA (C6H5N3)-H2O2 aqueous solutions was studied by using in-situ spectroscopic ellipsometry. A rapid flow cell was used and initial changes in an ellipsometric parameter, Δ, which corresponds to the layer thickening, were discussed. BTA forms a passivation layer and the oxidation from H2O2 precedes that.

Cleaning is an important process in the semiconductor manufacturing process. If cleaning is insufficient, contaminating particles will remain on the substrate, causing device failures. We have been studying the evaluation method for developing a new cleaning process. We are focusing on a spectroscopic ellipsometry, which can easily determine the structure of an extremely thin surface layer of sub nm even at the laboratory level, expecting application to particle detection. In this research, we tried detection of nanoparticles on the substrate by using ellipsometry, especially as a simple evaluation method in the laboratory, and proved its usefulness. An industrial inkjet printer was used for precise particle attachment.

In recent years, due to demands for lighter, thinner, shorter and more multifunctional electronic devices, it is necessary for the inside printed circuit board to be drilled with high precision. To solve this problem, we propose a drilling machine tool equipped with a counter balance damping system driven by left and right ball screws to reduce vibration. The vibration measurement, the vibration mode analysis and the vibration model of this machine tool showed that the vibration characteristics are greatly affected by the displacement of the center of gravity of the spindle and counter part.

An important facet of the contouring performance of machine tools with computer numerical control (CNC) is the machining of workpieces within the desired accuracy and within as short a time as possible. However, conventionally, the accuracy (error) and the speed are evaluated separately. Therefore, in this research, a method is proposed to evaluate the speed and accuracy of CNC machine tools using two-dimensional representations of error and speed based on actual trajectories. Experiments have verified that it is possible to quantitatively evaluate the speed and accuracy of multiple CNC machine tools using two-dimensional graphs of maximum error and actual speed.

In this study, we call the system, which combines In-situ observation of a tool and acquisition of machining information, ″integrated monitoring system″. This system has an aim to establish as a basic device of processing information collection based on IoT. In this report, the concept of the integrated monitoring system was proposed. And a series of data acquisition experiments for milling machine with dynamometer and high-speed camera were conducted. The wet-machining-tool- monitoring-system developed by AIST, also used as camera system. Those results showed validity of our concept and possibility that effective tool management and immediate finding of the optimized cutting condition is achieved.

In the next-generation optical satellite, improvement of the thermal stability of the optical system is required.As a mirror material of this system, zero expansion ceramic (NEXCERA) is considered to be a promising material to substitute for conventional zero expansion glass. High precision machining of super lightweight aspheric mirror is crucial for satellite mirror. In this presentation we will present the polishing properties of NEXCERA, the precise polishing of parabolic mirror using sub-aperture tools, and the precise polishing of the hyperbolic mirror using MRF.

Low-cost disposable endoscopes are highly demanded because it is difficult to completely prevent infection by endoscopy. We propose an endoscope with an insert molded integrated optics connected to a pair of polymer optical fibers. The integrated optics consists of an aspheric imaging lens and an illumination prism. The lens forms an in-vivo image on a facet of a multicore fiber to transfer to an imaging device, while the prism illuminates target to be observed using light delivered from a single core fiber. The integrated optics is designed using ray-tracing calculations, which size is 2.5mm wide and 3.9 mm high. Furthermore, we developed facet polishing technique for polymer fiber and molding process for manufacturing. Image acquisition experiments are successfully performed using the developed optics.

This paper describes the measurement of the discharge reaction force in EDM caused by the metal vapor jets from the copper, brass and zinc coated brass wires using a high-precise laser displacement sensor in a single discharge process. Then, based on the above experiments, the influence of the discharge duration and the boiling point of the tool electrode materials on the discharge reaction force were investigated. The experimental results show that lower boiling point of the tool electrode material results in larger discharge reaction force, and longer discharge duration also causes larger discharge reaction force. Furthermore, the value of the discharge reaction force was calculated based on the experimental results using the inverse method.

A new method, WECG (wire electrochemical grinding), for tungsten machining with neutral electrolyte and bipolar current is proposed, and the running wire is used as the tool electrode. The problem of tool wear inevitable due to the bipolar current was eliminated because the running wire is used as tool electrode with this method. Three kinds of wire guides were used, the cylindrical cemented tungsten carbide (WC) guide, cylindrical zirconium oxide (ZrO2) guide and plate cemented WC guide, to investigate the differences in the machining characteristics. The experiment results showed that the plate cemented WC wire guide generated a higher machining accuracy because of the less influence of stray current flowing through the gap formed by the machined micro-rod and wire guide. Even if the ZrO2 material has a much lower electrical conductivity than that of the cemented WC, the machining process was also influenced by the stray current between the micro-rod and wire guide. The tungsten micro-rod of 100 μm in diameter was machined with the length of 850 μm.
