Problems solved by technology

However, with this method, resist coating, exposure, development, etching, and resist stripping must be performed separately for each substrate, and expensive silicon substrates must be used.
Therefore, the production efficiency is low and it is difficult to reduce the cost of fuel cells
[0039] Therefore, there is a problem that the separator for a fuel cell with a multi-stage structure formed with high precision cannot be efficiently produced by the conventional method.

Embodiment approach 1

[0085] figure 1 The manufacturing process of the resin molded article in this embodiment is shown. The manufacturing apparatus used for realizing this embodiment is a well-known apparatus, and detailed description thereof will be omitted. refer to figure 1 The production method of this embodiment will be described. Furthermore, figure 1 An example using a chemically amplified negative resist is shown. In the resist pattern forming method of this scheme, the following processes are performed:

[0086] (i) forming the first resist layer on the substrate [ figure 1 (a)]

[0087] (ii) Alignment position of substrate and mask (A) [ figure 1 (b)]

[0088] (iii) Exposure of the first resist layer using mask (A) [ figure 1 (b)]

[0089] (iv) heat treatment of the first resist layer [ figure 1 (b)]

[0090] (v) forming a second resist layer on the first resist layer [ figure 1 (c)]

[0091] (vi) Alignment position of substrate and mask [ figure 1 (d)]

[0092] (vii) Exp...

Embodiment

[0154] According to the present invention, a method of forming a resin molded article will be described more specifically below with reference to the drawings. refer to figure 1 (a) First, the first resist coating based on an organic material ("PMER V-CA 3000PM" manufactured by Tokyo Ohka Industry Co., Ltd.) is performed on the substrate. And, refer to figure 1 (b) After forming the first resist layer, the substrate is aligned with the mask A processed into a desired mask pattern.

[0155] Then use a UV exposure device (Canon "PLA-501F" wavelength 365nm, exposure amount 300mJ / cm 2 ), and after exposing the first resist layer to UV light, heat treatment of the first resist layer was performed using a hot plate (100° C.×4 minutes).

[0156] refer to figure 1 (c) First, a second resist coating based on an organic material ("PMERN-CA 3000PM" manufactured by Tokyo Ohka Industry Co., Ltd.) is performed on the substrate. Then, refer to figure 1 (d) After forming the second resi...

Embodiment approach 2

[0173] use Figure 8 The method of manufacturing the metal structure (mold) and the resin molded article of the present embodiment will be described. Figure 8 It is a sectional view showing the manufacturing process of the metal structure (mold) of this embodiment. 51 is the substrate, 52 is the first layer resist, 53 is the first layer mask, 54 is the first intermediate structure, 55 is the second layer resist, 56 is the second layer mask, 57 is The second intermediate structure, 58 is a metal structure (mold). The mold is an example of the metal structure according to this embodiment. Since the same steps as those in the above-mentioned embodiment are the same as those described in Embodiment 1, description thereof will be omitted.

[0174] The resist coating step will be described. Firstly, a first-layer resist 52 based on an organic material (for example, “AZP 4400” manufactured by Kuraray, Japan) is coated on the substrate 51 . The resist 52 is a positive photosensi...

Abstract

A resin molded product production process has a resist pattern formation step including formation of the first resist layer on s substrate, positioning of the substrate and a mask A, exposure of the first resist layer using the mask A, heat-treatment of the first resist layer, formation of the second resist layer on the first resist layer, positioning of the substrate and a mask B, exposure of the second resist layer using the mask B, heat-treatment of the second resist layer, and development of the resist layers, thereby creating a given resist pattern. The production process further has a metal structure formation step of depositing a metal on the substrate in accordance with the resist pattern by plating, and a molded product formation step of forming a resin molded product by using the metal structure as a mold. A resin molded product is thereby produced.

Description

technical field [0001] The present invention relates to a method for producing a resin molded product having a desired molding depth or different depths of concavities and convexities, a resin molded product obtained by the method, and a method for producing a metal structure used in the production of the resin molded product. In particular, the method of the present invention is a method used as a method for manufacturing a resin molded product used in the fields of clinical examination, gene processing, and combinatorial alchemy, such as diagnosis, reaction, separation, and measurement, or a fuel cell flow path member. . Background technique [0002] Today, with the maturity of society, the value of medical care and health is changing from the narrow range of basic health to the pursuit of "rich and healthy life". In the context of this change in values, medical expenses are increasing, or the number of people in the borderline range of health and disease is increasing. ...
