Problems solved by technology

[0026] However, the main body of the synchrotron radiation facility alone costs 3 to 5 billion yen, and the cost of metal structures manufactured by lithography using this facility is estimated to be around 3 to 5 million yen each
Therefore, although the cost of resin molded products varies due to the number of molded sheets, it is about 20 times more expensive than resin molded products usually produced by lithographic printing using UV light, so it cannot be added as a cheap product at present. promotion

Embodiment 1

[0152] «Example 1» [Manufacture of a molded article having a flow path]

[0153] The resist layer forming step was repeated 3 times according to the method for forming a molded article shown in FIG. figure 2 A molded product having a flow path of 100 μm in width and 100 μm in depth was produced on a substrate of 60 mm in width by 50 mm in length and 1.5 mm in thickness as shown.

Embodiment 2

[0154] «Example 2» [Manufacture of a molded article having a flow path and a mixing portion]

[0155] The resist layer forming step was repeated 3 times according to the method for forming a molded article shown in FIG. image 3 A molded product having a flow path and a mixing portion having a width of 100 μm and a depth of 100 μm was produced on a substrate of 50 mm in width x 70 mm in height and 1.5 mm in thickness as shown.

Embodiment 3

[0156] «Example 3» [Manufacture of a molded article having a container]

[0157] The resist layer forming step was repeated 7 times according to the method of forming a molded article shown in FIG. Figure 4 A molded product having a container with a width of 200 μm and a depth of 250 μm was produced on a substrate of 60 mm in width×40 mm in height and 1.5 mm in thickness as shown.

[0158] The molded article obtained by the present invention can achieve high dimensional accuracy and the like compared with conventional molded articles. Furthermore, since such a molded product can be manufactured inexpensively while achieving precision, it is effective in being able to utilize the merits of efforts to control manufacturing costs and to use it in mass production.

Abstract

A resin molded product according to this invention is produced as follows. In this step, (a) formation of the first resist layer on a substrate (b) exposure of the first resist layer using a mask (c) formation of the second resist layer (d) mask positioning (e) exposure of the second resist layer are performed, and the steps (c) to (e) are repeated a plurality of times until a desired thickness of the resist layer is obtained. Then, development is performed to form a desired resist pattern. Secondly, a metal structure formation step is performed to deposit a metal structure in accordance with the resist pattern by plating. Finally, a molded product formation step is performed to form a resin molded product by using the metal structure as a mold. An accurate and low-cost resin molded product and a production process therefor are thereby provided.

Description

technical field [0001] The present invention relates to a method for producing a precise and inexpensive resin molded product having a desired molding depth, and the resin molded product obtained therefrom. The method of the present invention is particularly suitable for the production of resin moldings used in diagnosis, reaction, separation, and metering in fields such as medical treatment, industry, and biotechnology. The resin molded product obtained by the present invention, especially the resin molded product used in the medical field, can be effectively used in clinical examination clinics, hospital beds, etc., because of its fine structure, which can shorten the measurement time, reduce sampling, and parallel processing. Side, operating room, street clinic, family diagnosis, etc. Background technique [0002] With the development of society, the value of medical care and health has changed from basic health in a narrow sense to the pursuit of "surplus and healthy li...
