1. Terutake Hayashi, Nanoparticle sizing method based on fluorescence anisotropy analysis, Measurement, vol. 59, 382-388, 2015.01, Demand for applications of nanoparticles in electric architecture has been increasing. Nanoparticles provide new opportunities for improving circuit response. We discuss a novel method for evaluating nanoparticle sizes based on fluorescence anisotropy analysis. Particle size evaluation is possible through measurements of the rotational diffusion coef- ficient, which is sensitive to particle size. We develop a system for measuring rotational diffusion coefficients by using a fluorescent probe to label a particle. We report fundamen- tal experiments that verify the feasibility of the proposed method. The rotational diffusion coefficients of gold nanoparticles with diameters ranging 6–20 nm were measured using the proposed method. The measured rotational diffusion coefficients decrease with increasing particle size. This finding indicates that nanoparticles smaller than 15 nm can be measured with fine resolution..

This study proposes a new method of measuring stylus sphere diameters for micro-CMMs based on the analysis of whispering gallery modes (WGMs). Depending on the incident wavelength, different WGMs will be excited in the probe stylus, resulting in a wavelength spectral fingerprint that is related to the sphere diameter. In this paper, the diameter of the microprobe stylus sphere was determined with a least-squares method using theoretical and measured spectra of WGMs.
The measurement results showed that the precision of the proposed method was nm..

5. Jiaqing Zhu, Terutake Hayashi, Syuhei Kurokawa, Study on particle size distribution measurement using nanoparticle micro array, International Symposium on Measurement Technology and Intelligent Instruments, 2020.07, Nanoparticle is widely used in industrial production, such as biological sensor, pigment and slurry in CMP (Chemical Mechanical Polishing). Particle size distribution is used in the quality evaluation of nanoparticle. It is important to measure the particle size distribution of primary particle for the mixture solution of both primary and secondary particle. Image analysis method is able to accurately measure the geometric diameter of primary particle, even though secondary particle is present in solution. It is able to solve the problem that the result of DLS (Dynamic Light Scattering) is unreliable when secondary particle is present in solution. It is necessary that it takes a lot of time to observe thousands of particles. The aggregation of particles is also a problem during sample preparation from solution. It causes that it is difficult to confirm the presence of secondary particle in the solution. In this research, in order to accurately measure average diameter of primary particle and classify types of particle as primary particle or secondary particle, we suggest a new sample preparation method that called “nanoparticle micro array”. In this method, first nanoparticles are uniformly dispersed in solution. Then these nanoparticles are sampled one by one from the solution and arranged on silicon wafer in a high density and uniformly-spaced position. After the solution was evaporated, the sample is observed by SEM (Scanning Electron Microscope)/AFM (Atomic Force Microscope). And the geometric diameter of primary particle is measured from the SEM/AFM image. In this report, in order to verify the feasibility of particle characterization using “nanoparticle micro array”, we performed a fundamental experiment to classify particles and measure primary particle size distribution on a nanoparticle chip..

8. Terutake Hayashi, Syuhei Kurokawa, Study on diffusion coefficient evaluation for free abrasives and chemicals by using fluorescent anisotropy analysis, The 18th International Conference On Mechatronics Technology, 2014.10, CMP (Chemical Mechanical Polishing/ Planarization) for semiconductor production has become increasingly important to integrate the multi-layer circuits. CMP is a process of smoothing wafers surface with the both chemical reaction in slurry and mechanical polishing by using polishing pad and abrasives. In this research, we aim at the high-efficiency and high quality CMP of semiconductor wafer. We investigate fundamental property of CMP process in the aspect of polishing and alternation based on observing the diffusion of abrasive and chemicals. We consider the translational diffusion is related to the frequency of the contact for the free abrasives and chemicals on the surface of the material. Thus, the translational diffusion coefficient is considered to be related the change of the surface integrity and the material processing properties, such as removal rate, surface roughness, and flatness. In this paper, we suggest a novel measurement method for the translational diffusion coefficient based on the measurement of the fluidity of the slurry. The fluidity of slurry is measured by using fluorescence anisotropy analysis. We develop a system for measuring fluidity of slurry by using a fluorescent probe. The fundamental experiments are performed to verify the feasibility of the proposed method..
