  • Publication number: 20060254933
    Abstract: In a device for transporting liquid, liquid to be transported is enclosed by an oil droplet, which is fractionated with air, for manipulation. Moreover, as a method for supplying liquids wherein a plurality of liquids are enclosed by an oil droplet sequentially and treated, liquid enclosed by an oil droplet is formed by associating one oil with one liquid in a liquid introducing section. According to the present invention, even in the case where a plurality of liquids are manipulated, it is possible to manipulate stably without affecting other liquids. Moreover, it is possible to treat as a liquid enclosed by an oil droplet successively in the device for transporting liquid, thereby allowing the invention to be applied to a system for analyzing easily.

  • Publication number: 20060097155
    Abstract: Conventional liquid transport substrates having a fluid channel formed along an array of electrodes have a problem in which throughput decreases, depending on driving conditions. In order to avoid two-way passage in a fluid channel from the inlet to a measuring section and a fluid channel from the measuring section to the outlet, the measuring section is located in the middle of the fluid channel connecting the inlet and the outlet, so that manipulation from the inlet to the outlet takes place in one direction on the substrate. Even when analyzing a large number of sample droplets, by transport of the droplets substantially in one direction, it is possible to complete measurement in a short time.

  • Publication number: 20050259261
    Abstract: The adverse effect on measurement accuracy brought about by the transmission of light beams through portions of a liquid sample with different concentrations, i.e., a concentration distribution in the vertical direction of a container, is prevented by using semiconductor light sources of two different types with different wavelengths. The semiconductor light sources (2, 4) of two different types are housed in the same package (5) such that a detector (9) can capture the light beams emitted by the light sources after their optical axes have intersected with one another. The multiple light beams can be thus caused to pass through portions with substantially the same concentration and therefore can be detected without being influenced by the difference in concentration of the sample in the container.

  • Publication number: 20040048554
    Abstract: To solve a problem of non-uniform polishing properties of a circumferential surface area of a substrate, so-called edge sagging phenomenon. When a thin film formed on a top surface of the substrate is polished while holding a back surface of the substrate, local stress at a circumferential end of the substrate is reduced by a guide installed so as to surround the substrate. Also, a deformation of the outer circumferential end portion of the substrate is reduced by a recessed groove provided on the guide. Since a thin film formed on the surface can be polished to be flat throughout the surface of the substrate without an occurrence of non-uniform polishing properties of the outer circumferential surface area of the substrate, so-called edge sagging phenomenon, a high-performance semiconductor device can be manufactured at a high yield and low costs.
