Description
The present invention relates to a nail beauty instrument and a method of manufacturing the same. More particularly, the present invention relates to a nail beauty instrument and a method of manufacturing the same. More particularly, By providing a center groove portion having a diameter smaller than that of the circular groove portion, the polishing efficiency is improved because the polishing is also performed at the centers of the respective arrays, and the photosensitive resin is formed so as to stick to the surface of the substrate well, And a method of manufacturing the same.
In general, nail care equipment consists mostly of sandpapers. The nail surface is polished by using sand paper with alternate particle sizes, and then polished with a polisher, or a separate polish is applied to protect the surface. However, a lot of hair salon or nail art shop that deals with many customers needs to clean up many customers' nails in a short period of time. However, when using different types of sand filters with different grain sizes, it takes a long time to clean the nails. There is a disadvantage that washing and drying time are additionally required since the nail should be polished and then washed with water to clean the nails of other customers in a clean state.
In view of this, the prior art No. 723456 is a cutting structure that is repeatedly arranged in the same shape repeatedly on a plate-shaped glass surface so that the nail surface and the end thereof can be cut and polished at a time. The cutting structure has a polygonal shape, And a flat surface portion in the form of a square in four sides of the corrosion groove is formed on the surface so that the boundary line between the flat portion and the corrosion groove portion on the surface is formed by the cutting edge so that the polishing and polishing of the nail are simultaneously performed. I have proposed a nail beauty instrument.
In the conventional technique, a nail is cut in a cut groove portion and is polished while being polished in a flat portion.
However, since the flat portion is formed in a square shape and the cutting groove is surrounded by the flat portion, there is a technical problem that the nails beauty instrument has directionality so that the nails are only caught and not polished when the nails are trimmed in diagonal directions. That is, when the nail-beauty instrument is moved in a square shape, the cutting and polishing are performed at the same time, since the flat portion and the cutting groove are alternately arranged in a state in which the flat portion is placed in a square form. On the contrary, when the flat portion is moved in the diagonal direction, There was a problem that it was not polished because it was so sharp, and it only had to be cut.
In the prior art, the photoresist and the etching process of the semiconductor manufacturing process are used. In this case, since the photosensitive resin to which the glass surface is smoothly applied is easily dropped, chromium is first coated on the glass surface so that the photosensitive resin is coated on the glass surface A pretreatment technique was used. However, since the equipment according to the chromium coating is expensive and the coating time is long, the manufacturing cost is increased. Further, the patterned portion of the photosensitive resin after exposure is chemically treated to remove the chromium, The glass surface must be finally etched back, which complicates the process.
The prior art No. 846444 also discloses that the recessed portion and the planar portion are formed on the surface of the substrate in a repeated irregular pattern alternating with each other in the length and width direction of the substrate so that the boundary between the recessed portion and the planar portion becomes the cutting edge.
However, when the concave portion is formed in a rectangular shape, the corner portions of the concave portions are adjacent to each other, and when the nail is trimmed in the adjacent direction, there is a disadvantage in that the nail is only caught by the corners and is not polished. In addition, even if the concave portion is formed in a circular shape, if the circular concave portion and the concave groove portion are too close to each other, the area of the planar portion is reduced to degrade the polishing performance. On the other hand, if the concave portion is separated from the concave portion, There is a problem that the number of the recesses is reduced in a substrate having a limited area, resulting in poor cutting performance.
In addition, prior art No. 846444 uses a photoresist and an etching process in a semiconductor manufacturing process. However, there has been a technical problem in that chromium should be coated so that the photosensitive resin adheres well to the surface of the substrate.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a method of manufacturing a semiconductor device, which comprises etching the substrate surface to form circular recesses in a rectangular or triangular arrangement, By providing a center groove portion having a diameter smaller than that of the circular groove portion, the polishing efficiency is improved because the polishing is also performed at the centers of the respective arrays, and the photosensitive resin is formed so as to stick to the surface of the substrate well, And a method of manufacturing the same.
In order to achieve the above object, the present invention provides a method of polishing a surface of a substrate by etching a circular groove to repeatedly form the nail, thereby grinding the nail cut at the non-etched flat portion between the circular grooves, Wherein a central groove portion having a diameter smaller than that of the circular groove portion is formed in an etching process in a plane portion of the center of the arrays so that the nail is formed in the center of the arrays, .
According to the present invention, a circular groove portion is formed by etching on the surface of a substrate, and an unetched flat portion is formed between the circular groove portions so that the surface of the nail is cut by the circular groove portion and polished by the plane portion . At this time, the circular groove portion is formed of any one of a rectangular array, a rhombic array, or a triangular array. The centers of these arrays have a larger planar portion between adjacent circular grooves, resulting in non-uniformity of the planar portions.
If the area of the planar portions is non-uniform, there is a difference in the amount of polishing between the adjacent planar portions of the circular groove and the planar portions located at the center of the arrangement, so that the uniform polishing is not performed, The problem is that there is more gloss than the lesser one.
In an embodiment of the present invention, a center groove portion having a diameter smaller than that of the circular groove portion is formed at the center of the arrangement of the circular groove portions so as to solve the problem, and a flat portion positioned at the center of the arrangement, By preventing the difference from occurring, the polishing is performed even at the center of the array. Thereby, the directionality of polishing is eliminated and homogeneous polishing can be performed.
And a composition in which the photosensitive resin adheres well to the surface of the substrate and the portion exposed to ultraviolet rays after exposure is removed and the remaining portion has acid resistance resistant to acid in the etching process. Accordingly, since the chromium coating process used for the pretreatment on the surface of the conventional substrate is omitted, the manufacturing process is simplified and the productivity is improved. Moreover, since there is no need to provide chromium coating equipment, the manufacturing cost can be reduced.

The photosensitive resin of one embodiment of the present invention was developed for the purpose of coating a glass material to protect the material during physico-chemical processing and to stick to the surface of the material. The above-mentioned photosensitive resin has a property of being able to realize a photosensitive property with an epoxy resin such as urethane long-chain polyol or bisphenol type or phenol type. By the addition polymerization method as follows to synthesize a photosensitive resin.
The primary reaction is preferably carried out in the presence of an acid anhydride having reactivity with urethane long chain polyol (polyethylene glycol, polypropylene glycol, PC, PCD) or epoxy resin (bisphenol type, phenol type, etc.) Acrylic acid and the like) and a reactive monomer (acrylate monomer such as 2-HEMA, HEA, GMA, N-vinylpyrrolidone, etc.) were sequentially subjected to addition polymerization.
Each reaction sequence was 1 ~ 4HR by addition of acid anhydride, 1 ~ 4HR by addition of reactive monomer, or addition reaction by acid anhydride and reactive monomer. As a reaction for giving the photoreactivity, 10 parts by weight of the photo-initiator was added to 100 g of the reactant, and the photosensitivity was tested using an 8 kw photocoupler for a printed circuit board (PCB).
Photoreactive initiators were subjected to photosensitization tests using commercially available photocuring initiators such as acetophenone, 2.2.-methoxy-2-phenylacetophenone, dichloroacetone phenone, trichloroacetophenone and the like.
TPO (Photoinitiator): Mono Acyl Phosphine (Hydroxylcetoe series), and Photoinitiator are photoinitiators that help make the oligomer and monomer chemically bond to the desired resin.
DPHA (monomer): dipentaerythritol hexaacrylate.
Barium sulphate (Baso4) solid additive: Function of resin filler (Pattern formation).
BYK-333: Polyether-modified polydimethylsiloxane series Solvent-free, solvent-free, waterborne coatings with strong surface tension reducing effect and additives for silicone surfaces for printing inks.
YDCN: Cresol novolak type epoxy resin. Due to its high curing density due to its multifunctional nature, it has excellent physical, chemical and electrical properties and can be used as EMC and epoxy.
KD-404: Bisphenol-A type epoxy resin with mechanical and chemical properties.
Primary test results
100 parts by weight of a photosensitive resin reaction product and 5 to 20 parts by weight of a photoinitiator were mixed and stirred, and then the mixture was stirred at 300 meshes to be applied with a coating film thickness of 10 to 30 탆 and exposed to an exposure dose of 100 to 1000 mj.
(?: Very good,?: Good,?: Fair, X: poor)
The photoreactivity was different depending on the kind of photoinitiator, and the difference in the film formability was observed, but the above results were obtained at 500 ~ 1000mj.
The above first photosensitive reactive material can be used as an additive capable of imparting acid resistance to an epoxy resin or a phenolic resin.
In the second reaction, the addition reaction of the acid anhydride and the reactive monomer to the first reaction proceeded as described above. The reaction products obtained by the second reaction were increased in molecular weight and photoreactivity and the following results were obtained.
Second test result
100 parts by weight of a photosensitive resin reaction product and 5 to 20 parts by weight of a photoinitiator were mixed and stirred, and then the mixture was stirred at 300 meshes to be applied with a coating film thickness of 10 to 30 탆 and exposed to an exposure dose of 100 to 1000 mj.
(?: Very good,?: Good,?: Fair, X: poor)
The second photosensitive reactive material acts to increase light sensitivity and impart acid-resistant properties when attached to epoxy resins, phenolic resins, and other photosensitive reactive oligomers.
The light-sensitive resin synthesized over the first and second order has properties such as adhesion, chemical resistance and acid resistance, and is thermally cured by a photoreaction and a curing agent such as an amine-based thermal curing agent, an acid anhydride curing agent, dicyanediamide and melamine It can be coated on electronic parts material to achieve acid resistance.
The tertiary reaction is a synthesis that adds light sensitivity and film forming ability to the second reactant, thereby maintaining photoreactivity and facilitating workability. The third reaction was carried out by addition polymerization or addition of an acid anhydride and an epoxy resin to the second reaction product. Unlike the first and second reactions, the third reaction is a reaction process for developing, photocuring, chemical resistance, and film formation (when hot air is dried in a box oven at 80 ° C).
In the first and second synthesis, a photocuring film was formed to determine the film formation, chemical resistance and acid resistance. However, the third reaction was able to blow off the volatile matter by a hot air dryer and to confirm other properties after the film formation.
Third test result
100 parts by weight of a photosensitive resin reaction product and 5 to 20 parts by weight of a photoinitiator were mixed and agitated and printed at 300 mesh to coat a film thickness of 10 to 30 占 퐉 and irradiate an exposure amount of 100 to 1000 mj.
(?: Very good,?: Good,?: Fair, X: poor)
The reaction results confirmed that the tertiary reactant is formed as a coating film and that the solvent resistance, acid resistance, heat resistance and mechanical properties are realized during light irradiation.
The quaternary reaction is a process for realizing photolithography (photographic development type resist) as a process for imparting developability to a reactant having a coating film obtained in the above third reaction without inhibiting photoreactivity. An acid anhydride and a reactive monomer may be added to the tertiary reactant, or a melt reaction may be carried out.
The reaction product obtained as a result of the quaternary reaction can obtain a final resist having developability, light reactivity, solvent resistance, adhesion and mechanical properties.
Fourth test result
100 parts by weight of the photosensitive resin reactant and 5 to 20 parts by weight of the photoinitiator were mixed and stirred and printed in 300 mesh. The coating was applied in a thickness of 10 to 30 占 퐉, dried in a hot air drier at 80 占 폚 for 30 to 60 minutes, Respectively.
(?: Very good,?: Good,?: Fair, X: poor)
As a result of the test of the fourth reactant, it was found that the photoreactivity was slightly reduced but the developability was excellent. At low light exposure, the developability is excessively high and the film itself disappears due to the developer. If the light amount is appropriate, the range of pattern implementation when used as a development resist is wide.
Based on the results of the experiment, the following photosensitive resin composition was obtained.
