Abstract
Description
本發明係關於玻璃技術領域，特別是有關一種提升玻璃之機械強度的方法。This invention relates to the field of glass technology, and more particularly to a method of increasing the mechanical strength of glass.
目前許多產業，例如液晶顯示器產業，需要利用玻璃作為基板，藉由在基板上形成元件，例如薄膜電晶體，完成電子產品的製造。At present, many industries, such as the liquid crystal display industry, need to use glass as a substrate to complete the manufacture of electronic products by forming components, such as thin film transistors, on the substrate.
為了製程上的方便及成本考量，通常會先製作一大型尺寸玻璃，然後再根據需求將該大型尺寸玻璃以適當方式，例如以雷射切割成複數個中小型尺寸玻璃。For ease of processing and cost considerations, a large size glass is usually produced first, and then the large size glass is cut into a plurality of small and medium sized glass in an appropriate manner, for example, by laser.
請參閱第1圖，其係繪示玻璃10在切割後之側視圖，玻璃10之側表面100為切割面，其呈現如圖所示的微結構，即側表面100並非為一平坦的表面，整體呈現上下突出而中間內凹的形狀，更明確地說，玻璃10之上表面102與側表面100之交界處為尖銳的形狀，而玻璃10之下表面104與側表面100之交界處也為尖銳的形狀。Please refer to FIG. 1 , which is a side view of the glass 10 after cutting. The side surface 100 of the glass 10 is a cutting surface, which presents a microstructure as shown, that is, the side surface 100 is not a flat surface. The shape of the upper and lower projections is generally concave, and more specifically, the interface between the upper surface 102 of the glass 10 and the side surface 100 is sharp, and the boundary between the lower surface 104 of the glass 10 and the side surface 100 is also Sharp shape.
由於上表面102與側表面100之交界處、下表面104與側表面100之交界處非常尖銳，因此在後續製程，例如薄化製程中，遇到碰撞時會發生應力集中的情況，使得玻璃10產生裂紋或缺角，甚至造成玻璃10破裂的情況發生，進而導致玻璃10的生產良率不佳。Since the interface between the upper surface 102 and the side surface 100 and the boundary between the lower surface 104 and the side surface 100 are very sharp, in a subsequent process, such as a thinning process, stress concentration occurs when a collision occurs, so that the glass 10 is caused. Cracks or nicks are generated, and even the rupture of the glass 10 occurs, resulting in poor production yield of the glass 10.
此外，以玻璃10製成電子產品，例如手持式裝置螢幕時，也容易因為側表面100的機械強度脆弱，導致電子產品的品質不佳。In addition, when the electronic product is made of the glass 10, such as a hand-held device screen, it is also easy to cause the quality of the electronic product to be poor due to the weak mechanical strength of the side surface 100.
是以，確有需要對上述玻璃之側表面在切割後導致機械強度脆弱的問題提出解決方法。Therefore, it is indeed necessary to propose a solution to the problem that the side surface of the above glass causes the mechanical strength to be weak after cutting.
本發明之一目的在於提供一種提升玻璃之機械強度的方法，其能避免玻璃產生裂紋或缺角的問題。It is an object of the present invention to provide a method of increasing the mechanical strength of a glass which avoids the problem of cracking or missing corners of the glass.
本發明之另一目的在於提供一種提升玻璃之機械強度的方法，其能提升玻璃的生產良率。Another object of the present invention is to provide a method of increasing the mechanical strength of a glass which can increase the production yield of the glass.
為達成上述目的，本發明提供一種提升玻璃之機械強度的方法，該玻璃具有一上表面、一下表面以及至少一側表面，該方法包括：形成一保護層於該上表面及該下表面上，該保護層係曝露該上表面鄰近該側表面的區域及曝露該下表面鄰近該側表面的區域；蝕刻該玻璃之該側表面及該保護層之一側表面；以及移除該保護層。In order to achieve the above object, the present invention provides a method for improving the mechanical strength of a glass having an upper surface, a lower surface, and at least one side surface, the method comprising: forming a protective layer on the upper surface and the lower surface, The protective layer exposes a region of the upper surface adjacent to the side surface and a region exposing the lower surface adjacent to the side surface; etching the side surface of the glass and a side surface of the protective layer; and removing the protective layer.
本發明另一方面提供一種提升玻璃之機械強度的方法，該玻璃具有一上表面、一下表面以及至少一側表面，該方法包括：形成一保護層於該上表面及該下表面上，該保護層係覆蓋該上表面及該下表面；移除該保護層之一部分以曝露該上表面鄰近該側表面的區域以及曝露該下表面鄰近該側表面的區域；蝕刻該玻璃之該側表面及該保護層之一側表面；以及移除該保護層。Another aspect of the invention provides a method of enhancing the mechanical strength of a glass having an upper surface, a lower surface, and at least one side surface, the method comprising: forming a protective layer on the upper surface and the lower surface, the protection a layer covering the upper surface and the lower surface; removing a portion of the protective layer to expose a region of the upper surface adjacent the side surface and exposing a region of the lower surface adjacent the side surface; etching the side surface of the glass and the One side surface of the protective layer; and the protective layer is removed.
本發明之提升玻璃之機械強度的方法藉由蝕刻玻璃之側表面來使側表面從尖銳形狀變成平坦形狀，當側表面受到碰撞時不會有應力集中的情況，增強了玻璃的機械強度而不會在後續製程中產生裂紋或缺角的問題，進一步能提升玻璃的生產良率。The method for improving the mechanical strength of the glass of the present invention changes the side surface from a sharp shape to a flat shape by etching the side surface of the glass, and does not have stress concentration when the side surface is subjected to collision, thereby enhancing the mechanical strength of the glass without The problem of cracks or corners will be generated in the subsequent process, which further improves the production yield of the glass.
以下結合附圖對本發明的技術方案進行詳細說明。The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
請參閱第2A-2C圖，其係繪示根據本發明第一實施例之提升玻璃之機械強度的方法示意圖。Please refer to FIG. 2A-2C, which is a schematic view showing a method for improving the mechanical strength of the glass according to the first embodiment of the present invention.
要說明的是，第2A-2C圖所示為玻璃20之側視圖。It is to be noted that the 2A-2C diagram shows a side view of the glass 20.
於第2A圖中，玻璃20具有一上表面202、一下表面204以及至少一側表面200、206。玻璃20係從一大型尺寸玻璃經過切裂製程而得之小型尺寸玻璃。側表面200、206即為切裂製程中的切割面。In FIG. 2A, the glass 20 has an upper surface 202, a lower surface 204, and at least one side surface 200, 206. The glass 20 is a small-sized glass obtained by a slitting process from a large-sized glass. The side surfaces 200, 206 are the cutting faces in the dicing process.
於本步驟中，形成一保護層22於上表面202及下表面204上，於本實施例中，保護層22係曝露上表面202鄰近該側表面200的區域及曝露下表面204鄰近該側表面200的區域，也就是說，上表面202鄰近該側表面200的區域並未形成有保護層22，同樣地，下表面204鄰近該側表面200的區域也未形成有保護層22。In this step, a protective layer 22 is formed on the upper surface 202 and the lower surface 204. In this embodiment, the protective layer 22 exposes the area of the upper surface 202 adjacent to the side surface 200 and the exposed lower surface 204 is adjacent to the side surface. The region of 200, that is, the region of the upper surface 202 adjacent to the side surface 200 is not formed with the protective layer 22, and likewise, the region of the lower surface 204 adjacent to the side surface 200 is also not formed with the protective layer 22.
要說明的是，後續步驟需進行蝕刻製程，保護層22之作用在於避免保護層22所覆蓋之玻璃20之上表面202及下表面204被蝕刻，因此保護層22必須為具有抗酸鹼侵蝕能力的材料，才能防止蝕刻過程中產生的側蝕或保護層22剝離的現象。於一實施例中，將一膠膜貼附於上表面202及下表面204以形成保護層22。於另一實施例中，將有機材料、高分子材料或金屬材料塗佈或鍍膜於上表面202及下表面204以形成保護層22。It should be noted that the etching process is performed in the subsequent step, and the protective layer 22 functions to prevent the upper surface 202 and the lower surface 204 of the glass 20 covered by the protective layer 22 from being etched, so the protective layer 22 must have the resistance to acid and alkali corrosion. The material can prevent the side etching or the peeling of the protective layer 22 generated during the etching process. In one embodiment, a film is attached to the upper surface 202 and the lower surface 204 to form the protective layer 22. In another embodiment, an organic material, a polymeric material, or a metallic material is coated or coated on the upper surface 202 and the lower surface 204 to form the protective layer 22.
於第2B圖中，蝕刻玻璃20之側表面200及保護層22之側表面220，保護層22之側表面220為與玻璃20之側表面200相同側的一面。由於上表面202與側表面200交界處最為凸出，亦即上表面202與側表面200交界處最接近蝕刻液24，因此被蝕刻液24蝕刻的部分最多，而側表面200中點最為內凹，因此被蝕刻液24蝕刻的部分最少。In FIG. 2B, the side surface 200 of the glass 20 and the side surface 220 of the protective layer 22 are etched, and the side surface 220 of the protective layer 22 is the same side as the side surface 200 of the glass 20. Since the interface between the upper surface 202 and the side surface 200 is most convex, that is, the interface between the upper surface 202 and the side surface 200 is closest to the etching liquid 24, the portion etched by the etching liquid 24 is the most, and the midpoint of the side surface 200 is the most concave. Therefore, the portion etched by the etchant 24 is the least.
本發明之提升玻璃之機械強度的方法用於超薄玻璃時，經實驗可知，以低蝕刻率噴灑蝕刻液24來蝕刻側表面200及側表面220較易控制蝕刻程度且蝕刻效果較好。於一較佳實施例中，蝕刻率的範圍為1微米/分鐘(μm/min)至5微米/分鐘(μm/min)。When the method for improving the mechanical strength of the glass of the present invention is used for ultrathin glass, it has been experimentally found that the etching of the etching liquid 24 at a low etching rate to etch the side surface 200 and the side surface 220 is easier to control the etching degree and the etching effect is better. In a preferred embodiment, the etch rate ranges from 1 micrometer per minute (μm/min) to 5 micrometers per minute (μm/min).
此外，對於超薄玻璃而言，於一較佳實施例中，側表面200中點的水平方向蝕刻深度D1為20微米(μm)至60微米(μm)，保護層22曝露上表面202及下表面204的範圍則可視側表面200中點的水平方向蝕刻深度D1而定。In addition, for the ultra-thin glass, in a preferred embodiment, the horizontal etching depth D1 of the midpoint of the side surface 200 is 20 micrometers (μm) to 60 micrometers (μm), and the protective layer 22 exposes the upper surface 202 and the lower surface. The extent of surface 204 may depend on the horizontal etch depth D1 of the point in side surface 200.
至於側表面206也可以利用與蝕刻側表面200相同的方式進行蝕刻，此不多加贅述。As for the side surface 206, etching can also be performed in the same manner as the etching side surface 200, which will not be described again.
於第2C圖中，移除第2B圖之保護層22。如圖所示，上表面202與側表面200交界處變成圓弧狀，因此側表面200在受到碰撞時不會有應力集中的情況，增強了玻璃20的機械強度而不會在後續製程中產生裂紋或缺角的問題。In Figure 2C, the protective layer 22 of Figure 2B is removed. As shown in the figure, the boundary between the upper surface 202 and the side surface 200 becomes an arc shape, so that the side surface 200 does not have stress concentration when subjected to a collision, and the mechanical strength of the glass 20 is enhanced without being generated in a subsequent process. Crack or missing corner problem.
請參閱第3A-3D圖，其係繪示根據本發明第二實施例之提升玻璃之機械強度的方法示意圖。Please refer to FIG. 3A-3D, which is a schematic diagram showing a method for improving the mechanical strength of a glass according to a second embodiment of the present invention.
要說明的是，第3A-3D圖所示為玻璃30之側視圖。It is to be noted that the 3A-3D diagram shows a side view of the glass 30.
於第3A圖中，玻璃30具有一上表面302、一下表面304以及側表面300、306。玻璃30係從一大型尺寸玻璃經過切裂製程而得之小型尺寸玻璃。側表面300、306即為切裂製程中的切割面。In FIG. 3A, the glass 30 has an upper surface 302, a lower surface 304, and side surfaces 300, 306. The glass 30 is a small-sized glass obtained by a slitting process from a large-sized glass. The side surfaces 300, 306 are the cutting faces in the dicing process.
於本步驟中，形成一保護層32於上表面302及下表面304上，要注意的是，本實施例之保護層32係完整覆蓋上表面302及下表面304，而第一實施例之保護層22係曝露上表面202的一部分及下表面204的一部分。In this step, a protective layer 32 is formed on the upper surface 302 and the lower surface 304. It should be noted that the protective layer 32 of the embodiment completely covers the upper surface 302 and the lower surface 304, and the protection of the first embodiment. Layer 22 exposes a portion of upper surface 202 and a portion of lower surface 204.
要說明的是，後續步驟需進行蝕刻製程，保護層32之作用在於避免保護層32所覆蓋的範圍被蝕刻，因此保護層32必須為具有抗酸鹼侵蝕能力的材料，才能防止蝕刻過程中產生的側蝕或保護層32剝離的現象。於一實施例中，將一膠膜貼附於上表面302及下表面304以作為保護層32。於另一實施例中，將有機材料、高分子材料或金屬材料塗佈或鍍膜於上表面302及下表面304以作為保護層32。It should be noted that the subsequent step requires an etching process, and the protective layer 32 functions to prevent the range covered by the protective layer 32 from being etched. Therefore, the protective layer 32 must have a material resistant to acid and alkali corrosion to prevent the etching process from occurring. The phenomenon of side etching or peeling of the protective layer 32. In one embodiment, a film is attached to the upper surface 302 and the lower surface 304 as the protective layer 32. In another embodiment, an organic material, a polymer material, or a metal material is coated or coated on the upper surface 302 and the lower surface 304 as the protective layer 32.
於第3B圖中，移除保護層32之一部分以曝露上表面302鄰近該側表面300的區域以及曝露下表面304鄰近該側表面300的區域，移除的方法例如切割或其他習知方式，此不多加贅述。In FIG. 3B, a portion of the protective layer 32 is removed to expose an area of the upper surface 302 adjacent the side surface 300 and an area where the lower surface 304 is exposed adjacent to the side surface 300, such as cutting or other conventional means, This is not to be repeated.
於第3C圖中，蝕刻玻璃30之側表面300及保護層32之側表面320，保護層32之側表面320為與玻璃30之側表面300相同側的一面。由於上表面302與側表面300交界處最為凸出，亦即上表面302與側表面300交界處最接近蝕刻液34，因此被蝕刻液34蝕刻的部分最多，而側表面中點最為內凹，因此被蝕刻液34蝕刻的部分最少。In FIG. 3C, the side surface 300 of the glass 30 and the side surface 320 of the protective layer 32 are etched, and the side surface 320 of the protective layer 32 is the same side as the side surface 300 of the glass 30. Since the interface between the upper surface 302 and the side surface 300 is most convex, that is, the interface between the upper surface 302 and the side surface 300 is closest to the etching liquid 34, the portion to be etched by the etching liquid 34 is the most, and the midpoint of the side surface is the most concave. Therefore, the portion etched by the etchant 34 is the least.
如同上述第一實施例，以低蝕刻率噴灑蝕刻液34來蝕刻側表面300及側表面320較易控制蝕刻程度且蝕刻效果較好。於一較佳實施例中，蝕刻率的範圍為1微米/分鐘(μm/min)至5微米/分鐘(μm/min)。As with the first embodiment described above, it is easier to control the degree of etching and the etching effect by spraying the etching liquid 34 at a low etching rate to etch the side surface 300 and the side surface 320. In a preferred embodiment, the etch rate ranges from 1 micrometer per minute (μm/min) to 5 micrometers per minute (μm/min).
對於超薄玻璃而言，於一較佳實施例中，側表面300中點的水平方向蝕刻深度D2為20微米(μm)至60微米(μm)，保護層32曝露上表面302及下表面304的範圍則可視側表面300中點的水平方向蝕刻深度D2而定。For ultra-thin glass, in a preferred embodiment, the horizontal etch depth D2 of the midpoint of the side surface 300 is 20 micrometers (μm) to 60 micrometers (μm), and the protective layer 32 exposes the upper surface 302 and the lower surface 304. The range may be determined by the horizontal etching depth D2 of the point in the side surface 300.
側表面306也可以利用與蝕刻側表面300相同的方式進行蝕刻，此不多加贅述。The side surface 306 can also be etched in the same manner as the etched side surface 300, which is not described in detail.
於第3D圖中，移除第3C圖之保護層32。如圖所示，上表面302與側表面300交界處變成圓弧狀，因此側表面300在受到碰撞時不會有應力集中的情況，增強了玻璃30的機械強度而不會在後續製程中產生裂紋或缺角的問題。In FIG. 3D, the protective layer 32 of FIG. 3C is removed. As shown in the figure, the boundary between the upper surface 302 and the side surface 300 becomes an arc shape, so that the side surface 300 does not have stress concentration when subjected to a collision, and the mechanical strength of the glass 30 is enhanced without being generated in a subsequent process. Crack or missing corner problem.
上述第一及第二實施例中，蝕刻液24、34至少包含氫氟酸(HF)，也可以使用氫氟酸並調配適量的硫酸(H2SO4)、鹽酸(HCl)或硝酸(HNO3)作為該蝕刻液。In the above first and second embodiments, the etching liquids 24, 34 contain at least hydrofluoric acid (HF), and hydrofluoric acid may be used and an appropriate amount of sulfuric acid (H 2 SO 4 ), hydrochloric acid (HCl) or nitric acid (HNO) may be formulated. 3 ) As the etching solution.
本發明之提升玻璃之機械強度的方法藉由蝕刻玻璃之側表面來使側表面從尖銳形狀變成平坦形狀，當側表面受到碰撞時不會有應力集中的情況，增強了玻璃的機械強度而不會在後續製程中產生裂紋或缺角的問題，進一步能提升玻璃的生產良率。The method for improving the mechanical strength of the glass of the present invention changes the side surface from a sharp shape to a flat shape by etching the side surface of the glass, and does not have stress concentration when the side surface is subjected to collision, thereby enhancing the mechanical strength of the glass without The problem of cracks or corners will be generated in the subsequent process, which further improves the production yield of the glass.
綜上所述，雖然本發明已用較佳實施例揭露如上，然其並非用以限定本發明，本發明所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。In view of the above, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the invention, and the present invention may be made without departing from the spirit and scope of the invention.
