- FIG. 1 shows an apparatus for carrying out the method for producing a photosensitive resist film for producing precision micromachined parts according to the present embodiment.
- 1 is a double-sided copper-clad laminate as an example of a conductive material such as a metal
- 2 is a photosensitive resist film
- 4 and 4 are a pair of pressure rolls
- 5 is porous after electrodeposition or after water washing.
- Area of the resist film 2 is the area of the continuous resist film 2 after roll press drying
- 8 is the air blow located on the front side of the roll press on the rolls 4 and 4 and on both the front and back sides of the laminate 1. It is.
- photosensitive resist refers to a water-dispersible liquid photosensitive resist that can be electrodeposited, and after the electrodeposition step, is heated and dried, and further subjected to an exposure-development-etching step. It can manufacture precision microfabricated parts such as printed wiring boards.
- photosensitive resists that can be electrodeposited include an anion type, which is electrodeposited on the anode, and a cationic type, which is electrodeposited on the cathode, and a negative type, in which the non-exposed area flows out during development.
- an anion type which is electrodeposited on the anode
- a cationic type which is electrodeposited on the cathode
- a negative type in which the non-exposed area flows out during development.
- the composition of the photosensitive resist solution there have been many proposals such as JP-A-3-17757, JP-A-2-42446, etc. It is an aqueous dispersion mainly composed of a photopolymerizable polymer, oligomer, monomer and photopolymerization initiator having a radical reactive functional group such as a vinyl group.
- the conductive material may be any conductive material that can be electrodeposited, and may be a metal such as copper, aluminum, or iron, and an alloy, an oxide, a conductive organic material, or an insulator of the metal. Substances.
- the electrodeposition coating after immersing the substrate to be electrodeposited in the photosensitive resist solution,
- the resist film 2 is formed on the substrate by energizing, and generally has a porous film structure immediately after energizing (see area 5 in Fig. 1), so heat it before using it as a resist. It is necessary to use a continuous film (see area 6 in Fig. 1).
- the resist liquid adhering to the film has different components from the film formed by electrodeposition, so that a uniform film is formed by washing with water and adhering to the film. It is preferable to remove the resist solution that has been applied.
- the roll curse with a pressure roll while heating is a method in which the resin roll is passed through a metal roll 4.4 coated with resin under the conditions of constant heating, pressure, and feed rate.
- the resist obtained by the roll breath drying method had a much higher resolution than that obtained by the conventional oven drying method.
- the reason for this is not clear yet, the continuous film formation by heating and melting is performed in a short time, and there is almost no dark reaction of the photosensitive resist due to the heat that has progressed by conventional long-time heating and drying. It is presumed that the developability improved and the resolution increased.
- the rolls 4 and 4 used in the roll press drying method may be resin-coated rolls in order to flatten the pressure and prevent the resist film 2 from being picked up (transferred to the roll side) on the rolls 4 and 4. desirable.
- Covered tree As the grease material, a flexible material having a JIS hardness (spring hardness test A type of JISK6301) having a heat resistance to withstand the use heating temperature of 10 to 100 is preferable. If the hardness is higher than this range, it is difficult to average the pressure, and drying cannot be uniform. On the other hand, those with low hardness have severe cracking and wear of the coating material, and may not be able to withstand repeated use.
- Materials that can be used include, for example, fluorine rubber, silicon rubber, urethane rubber and the like. In order to prevent pick-up of the resist on the surface of the mouth, it is also effective to apply release processing (for example, fluororesin processing) or release material application (for example, release agent or surfactant). It is.
- the roll temperature at the time of the roll breath is 60 to 200. C (preferably 100 to 160 ° C.). At temperatures lower than this range, the melting of the resist is not sufficient and a continuous film is not formed. On the other hand, on the high-temperature side, the resist undergoes a dark reaction due to heat, which not only lowers the resolution but also makes the removal of volatile components insufficient, and generates bubbles in the film.
- the roll passing speed should be set within such a condition that this bubble is not generated and drying is sufficient. Generally, 0.1 to 10 mZmin, preferably 0.5 to 2 niZniin is suitable.
- the resist film after electrodeposition can be dried and formed in a short period of time, and high productivity can be realized, and at the same time, drying of a thin plate of 0.4 mm or less, which has been conventionally difficult, can be easily performed. It became so. Furthermore, since a resist film with higher resolution can be formed than by the conventional drying method, it is suitable for high density and high precision printed wiring boards.
- a laminator dry film laminator
- a common inexpensive film material can be dried and laminated on both front and back surfaces of the laminated board 1 as a cover film 3.3 simultaneously with drying.
- reference numeral 7 denotes a region of the resist film 2 obtained by laminating the cover film 3.
- a light-transmissive and inexpensive material such as polyethylene, polypropylene, PET, cellophane, nylon, or PVC can be used.
- a laminate film of a cover film resist / substrate having the same structure as a general film-type resist (dry film resist) stuck on a substrate can be manufactured at low cost.
- This structure is effective in preventing dust adhesion and scratching during storage, and in stacking storage, but when used, be sure to remove the cover film 3.3 before the exposure or development process. You need to peel it off.
- a light-impermeable material such as a paper-colored plastic or metal foil can be used.
- a resist coated plate with a cover film was obtained in the same manner as in Example 1, except that roll press drying was performed using the apparatus shown in Fig. 2 while laminating a commercially available 20-thick polyethylene terephthalate film (PET film).
- PET film polyethylene terephthalate film
- Table 1 shows the results of obtaining a printed wiring board under the same conditions as in Example 1 except that a mask film was applied from above the cover film to irradiate ultraviolet rays, and then the cover film was peeled off and developed. Show.
- the resist film after the adhesion can be dried and formed in a short time, and high productivity can be realized, and at the same time, drying of a thin plate having a thickness of 0.4 mm or less, which has been conventionally difficult, can be easily performed. You can now. Furthermore, since a resist film can be formed with a higher resolution than the conventional drying method, it is suitable for high density and high precision printed wiring boards.
