Abstract: The present invention is a substrate for forming a patterned thin film by causing a specific fluid to adhere. More particularly, this substrate comprises a pattern formation region that is patterned in a specific shape in order to form a film. This pattern formation region is constituted such that an affinity region having an affinity to the fluid is disposed according to specific rules within a non-affinity region not having an affinity to the fluid. The fluid can be uniformly made to adhere to the required region, without spreading out too much or splitting up, allowing a uniform thin film to be formed.

Abstract: In order to form organic thin films on electrodes, a solution of a material for the organic thin film is accurately printed via an ink-jet onto the surface of microelectrodes as required, thereby producing a high density array of microelectrodes. Further, a solution of a sample substance or a liquid substance to be sensed is ejected into air via an ink-jet nozzle to fall to the surface of organic thin membranes on the microelectrodes so that the sample can be evaluated.

Abstract: A method of manufacturing a substrate with a pattern showing hydrophilic property formed on a pattern surface comprising the steps of applying a silane coupling agent to the pattern surface of the base and forming a silane coupling film, forming a mask conforming to the pattern to be provided on the silane coupling film, and activating the silane coupling film provided with the mask by applying energy thereto in order to generate a polar group. In the regions where masking could not be performed, a polar group such as the hydroxyl group, carboxyl group, amino group, or amino carboxyl group is generated and shows hydrophilic property. The masked regions comprise hydrophobic property. This substrate functions as a universal substrate suitable for forming patterns with the inkjet system.

Abstract: This invention relates to a liquid jetting structure which comprises a nozzle or nozzles 11 for jetting a liquid 6. What is characteristic of this liquid jetting structure is that a flow path inside the nozzle or nozzles is set so that the degree of affinity for the liquid 6 to be jetted changes in the direction of liquid flow (140, 130). By controlling the affinity in this way, the liguid getting structure is possible to improve the linearity of advance of the liquid droplets, and to stabilize the liquid droplet diameter. Such a liquid jetting structure is suitable for an ink jet recording head.
