Description

Technical Field

[0001] This application relates to the field of glass technology, and in particular to glass compositions, chemically strengthened glass, their applications and manufacturing methods. Background Technology

[0002] As semiconductor chip devices become increasingly integrated, carrier materials are needed in the chip packaging process to prevent wafer deformation and improve chip packaging yield. Currently, commonly used materials for chip packaging carriers include monocrystalline silicon wafers, metals, and ceramics. Monocrystalline silicon wafers have the advantage of a thermal expansion coefficient comparable to that of the monocrystalline silicon substrate being packaged, resulting in high mechanical strength and improved packaging yield, making them widely used. However, their fatal flaw lies in the temporary bonding between monocrystalline silicon wafers, which, while strong, makes peeling after packaging extremely difficult. While metals also possess high strength, bonding them to monocrystalline silicon substrates requires high-temperature temporary bonding, which can easily damage the circuit layers on the silicon wafer surface. Ceramic materials, although also strong, also require high-temperature bonding. Glass, due to its good mechanical stability, high light transmittance, and ability to achieve ultra-large sizes at a relatively low cost, is a material with great development potential for semiconductor chip packaging carriers. As a packaging carrier, glass is often manufactured into large-sized glass sheets. The higher the Young's modulus of the glass, the less prone it is to deformation during application. In particular, the higher the Young's modulus, the less likely the glass is to warp or break under stress during the packaging process, thereby improving the yield. Patent document CN113661148A discloses a glass that can be used for semiconductor packaging, but its Young's modulus needs further improvement. Summary of the Invention

[0044] <Essential and Optional Components>

[0045] SiO2 is a network-forming component that can improve the anti-crystallization properties and chemical stability of glass compositions and chemically strengthened glasses. It can also improve the mechanical properties and ultraviolet light transmittance of glass compositions and chemically strengthened glasses, and adjust the coefficient of thermal expansion. However, if the SiO2 content is too high, the meltability of the glass decreases, the high-temperature viscosity increases, and inclusions such as bubbles or stones are easily formed in the glass, reducing the intrinsic quality of the glass composition and chemically strengthened glass. Its refractive index is also difficult to meet design requirements. At the same time, the glass needs to be melted at higher temperatures. Higher melting temperatures lead to an exponential increase in the erosion of the crucible by the molten glass. The content of ions with strong absorption in the ultraviolet band, such as iron (Fe) ions and platinum (Pt) ions, rises rapidly, which in turn leads to a rapid decrease in the ultraviolet light transmittance of the glass composition and chemically strengthened glass. Therefore, in this application, the SiO2 content is 46.5% to 59%, optionally 48% to 57%, or optionally 50% to 55%.

[0046] B2O3 forms a network structure within the glass, promoting stable glass formation and improving the devitrification resistance of the glass composition and chemically strengthened glass, while also adjusting optical constants and the temperature coefficient of refractive index. However, excessively high B2O3 content leads to decreased chemical stability in the glass composition and chemically strengthened glass, and increased volatilization during glass melting. Therefore, the B2O3 content in this application is 4%–14%, optionally 6%–12%, and optionally 7%–11%. In some embodiments, the B2O3 content can be 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, etc., as well as all ranges and sub-ranges between these values.

However, if its content is too high, the optical constants of the glass compositions and chemically strengthened glasses will be difficult to reach the desired range, and the chemical stability will deteriorate. Therefore, the CaO content is 0-4%, optionally 0-3%, optionally 0.5%-2%. In some embodiments, the CaO content can be 0, greater than 0, 0.01%, 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2%, 2.3%, 2.5%, 2.7%, 3%, 3.3%, 3.5%, 3.7%, 4%, etc., as well as all ranges and sub-ranges between the above values.

[0052] ZnO can adjust the optical constants of glass compositions and chemically strengthened glasses, improve the melting point and ultraviolet light transmittance of the glass, and lower the transition temperature of the glass compositions and chemically strengthened glasses. However, if the ZnO content is too high, the dispersion of the glass compositions and chemically strengthened glasses increases significantly, making it difficult to achieve the desired optical constants, and is also detrimental to improving the mechanical properties of the glass compositions and chemically strengthened glasses, and results in excessively low high-temperature viscosity. Therefore, the ZnO content is 8.5% to 20%, optionally 11% to 18%, optionally 12.5% ​​to 16%. In some embodiments, the ZnO content can be 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 15%, 15.5%, 16%, 16.5%, 17%, 17.5%, 18%, 18.5%, 19%, 19.5%, 20%, etc., as well as all ranges and subranges between the above values.

Therefore, a SiO2 / (Al2O3+ZnO) ratio of 1.2 to 3.0 is optional, a SiO2 / (Al2O3+ZnO) ratio of 1.3 to 2.5 is optional, and a SiO2 / (Al2O3+ZnO) ratio of 1.5 to 1.9 is further optional.

[0055] Li₂O can lower the transition temperature and density of glass compositions and chemically strengthened glasses, and reduce high-temperature viscosity.

[0072] <Components that should not be present>

[0073] Fe2O3 can cause coloration in glass compositions and chemically strengthened glass, which is detrimental to achieving excellent light transmittance in glass compositions and chemically strengthened glass. Therefore, in some embodiments, it is optional to exclude Fe2O3.

[0074] Fluorine (F) volatilizes during glass melting, causing instability in the glass composition and reducing the quality of the glass composition and chemically strengthened glass. Therefore, in some embodiments, it is optional to omit F.

[0075] Oxides of transition metals such as V, Cr, Mn, Co, Ni, Cu, Ag, and Mo, even when contained individually or in small amounts in combination, can color glass compositions and chemically strengthened glass, causing absorption at specific wavelengths in the visible light region. This weakens the property of this application in improving visible light transmittance. Therefore, for glass where transmittance in the visible light region is required, it is preferable to omit the aforementioned components.

Environmental protection measures are essential not only in glass manufacturing but also in processing and post-product disposal. Therefore, given the importance of environmental impact, it is preferable to eliminate these substances, except where their contamination is unavoidable. Consequently, the glass composition and chemically strengthened glass become virtually free of pollutants. Therefore, even without specific environmental countermeasures, the glass composition and chemically strengthened glass of this application can be manufactured, processed, and disposed of.

After the raw materials are prepared according to conventional methods, the prepared furnace charge is put into a melting furnace (such as a platinum or platinum alloy crucible) at 1300-1600℃ for melting. After clarification and homogenization, a homogeneous molten glass without bubbles and undissolved substances is obtained. This molten glass is then cast in a mold and annealed. Those skilled in the art can appropriately select raw materials, process methods, and process parameters according to actual needs.

[0151] The glass composition of this application can also be formed by well-known methods. In some embodiments, the glass composition described herein can be manufactured into glass preforms by various processes, including but not limited to sheets, lenses, prisms, etc. These processes include, but are not limited to, slot drawing, float glass, roll forming, and other processes known in the art for forming sheets, lenses, and prisms. Alternatively, the glass composition can be formed by float glass or roll forming methods known in the art. The glass composition and glass preforms of this application can have any reasonably useful thickness, shape, or structure, such as 2D, 2.5D, or 3D.

[0152] The glass composition of this application can be used to manufacture sheet glass preforms by methods such as grinding or polishing, but the method of manufacturing glass preforms is not limited to these methods.

[0153] Glass preforms can be manufactured from the prepared glass composition using methods such as grinding, hot pressing, or precision stamping. Specifically, glass preforms can be manufactured by machining the glass composition, such as grinding and polishing; or by using a preform made from the glass composition for molding, then hot pressing and grinding the preform; or by precision stamping a preform made through grinding. It should be noted that the methods for preparing glass preforms are not limited to the methods described above.

[0154] Manufacturing methods for chemically strengthened glass:

[0155] The chemically strengthened glass of this application is obtained by chemically strengthening the glass composition or glass preform of this application. The manufacturing method of the chemically strengthened glass of this application includes the following steps: 1) forming a glass composition; 2) chemically strengthening the glass composition, or processing the glass composition into a glass preform and then chemically strengthening it. The chemical strengthening treatment described in this application includes immersing the glass composition or glass preform in molten sodium and / or potassium salts at a certain temperature (i.e., the chemical strengthening temperature) for a certain period of time. The sodium salt can be NaNO3, Na2SO4, NaCl, Na2CO3, etc., and the potassium salt can be KNO3, K2SO4, KCl, K2CO3, etc.

[0156] The glass composition or glass preform of this application can be used to manufacture chemically strengthened glass using a one-step chemical strengthening method (i.e., one-step chemical strengthening treatment) or a multi-step chemical strengthening method (i.e., multi-step chemical strengthening treatment). The one-step chemical strengthening method refers to immersing the glass composition or glass preform in molten sodium and / or potassium salts once; the multi-step chemical strengthening method refers to immersing the glass composition or glass preform in molten sodium and / or potassium salts two or more times, specifically, it can be a two-step chemical strengthening treatment, a three-step chemical strengthening treatment, a four-step chemical strengthening treatment, a five-step chemical strengthening treatment, etc.

[0157] In some embodiments, the chemical strengthening treatment of the glass composition or glass preform of this application may employ a one-step chemical strengthening method. The glass composition or glass preform is immersed in a molten salt containing sodium salt, which can be pure NaNO3 molten salt or a mixed molten salt composed of NaNO3 and KNO3 or other known common salt bath components and salt bath additives. This chemical strengthening method can achieve ion exchange with a high strengthening layer depth in the glass composition described in this application, increasing the glass composition's resistance to fracture, puncture, and crack propagation, and improving its four-point bending strength. For chemical strengthening, the higher the temperature, the faster the ion diffusion in the glass and the deeper the strengthening layer. However, excessively high chemical strengthening temperatures can easily cause stress relaxation, and the glass composition may suffer surface damage due to salt bath corrosion at high temperatures, affecting subsequent application performance; low chemical strengthening temperatures result in slow ion diffusion, a shallow strengthening layer, and an insignificant strengthening effect. Therefore, the chemical strengthening temperature in this application may be selected from 380–500°C, 420–490°C, and further from 440–480°C. In some embodiments, the first-step chemical strengthening temperature can be 380℃, 385℃, 390℃, 395℃, 400℃, 405℃, 410℃, 415℃, 420℃, 425℃, 430℃, 435℃, 440℃, 445℃, 450℃, 455℃, 460℃, 465℃, 470℃, 475℃, 480℃, 485℃, 490℃, 495℃, 500℃, etc., as well as all ranges and sub-ranges between the above values. Appropriately increasing the chemical strengthening time can increase the strengthening layer depth and improve the strengthening effect. However, if the chemical strengthening time is too long, it can easily lead to the volatilization and decomposition of the salt bath, causing impurities to adhere to the surface of the glass composition, and significantly reducing the salt bath life. Therefore, the chemical strengthening time of this application can be selected from 0.5 to 6 hours, from 0.5 to 4 hours, and further from 1 to 2 hours. In some implementations, the chemical fortification time can be 0.5 hours, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 4.5 hours, 5 hours, 5.5 hours, 6 hours, etc., as well as all ranges and subranges between the above values.

[0158] In some embodiments, the chemical strengthening treatment of the glass composition or glass preform of this application may employ a multi-step chemical strengthening method, more preferably a two-step chemical strengthening method, and further preferably, the glass composition or glass preform may be immersed in molten salt containing sodium salt and / or potassium salt for a two-step chemical strengthening treatment. The sodium salt may be NaNO3, and the potassium salt may be KNO3.

[0159] The first step of chemical strengthening involves Li-Na exchange, in which the glass composition or glass preform is immersed in a molten salt containing sodium salt. This molten salt can be pure NaNO3 molten salt or a mixed molten salt composed of NaNO3 and KNO3, or other known common salt bath components and salt bath additives. This first step of chemical strengthening achieves ion exchange with a high strengthening layer depth in the glass composition described in this application, increasing the glass composition's resistance to fracture, puncture, and crack propagation, and improving its four-point bending strength. For chemical strengthening, the higher the temperature, the faster the ion diffusion in the glass and the deeper the strengthening layer. However, excessively high chemical strengthening temperatures can easily cause stress relaxation, and the glass composition may suffer surface damage due to salt bath corrosion at high temperatures, affecting subsequent application performance. Conversely, low chemical strengthening temperatures result in slow ion diffusion, a shallow strengthening layer, and insignificant strengthening effect. Therefore, the first step of chemical strengthening in this application can be selected from 380–500℃, 420–490℃, and further from 440–480℃. In some embodiments, the first-step chemical strengthening temperature can be 380℃, 385℃, 390℃, 395℃, 400℃, 405℃, 410℃, 415℃, 420℃, 425℃, 430℃, 435℃, 440℃, 445℃, 450℃, 455℃, 460℃, 465℃, 470℃, 475℃, 480℃, 485℃, 490℃, 495℃, 500℃, etc., as well as all ranges and sub-ranges between the above values. Appropriately increasing the chemical strengthening time can increase the strengthening layer depth and improve the strengthening effect; however, excessively long chemical strengthening times can easily lead to the volatilization and decomposition of the salt bath, causing impurities to adhere to the surface of the glass composition, and significantly reducing the salt bath life. Therefore, the first-step chemical strengthening time in this application can be selected as 0.5 to 6 hours, 0.5 to 4 hours, and further selected as 1 to 2 hours. In some implementations, the first step of chemical strengthening time can be 0.5 hours, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 4.5 hours, 5 hours, 5.5 hours, 6 hours, etc., as well as all ranges and subranges between the above values.

[0160] The second step of chemical strengthening involves Na-K exchange. The glass composition or preform, after the first step of chemical strengthening, is immersed in a molten salt containing potassium salts. This molten salt can be pure KNO3 molten salt or a mixed molten salt composed of KNO3 and NaNO3, or other known common salt bath components and salt bath additives. Between the first and second steps of chemical strengthening, the glass composition or preform can be cleaned and annealed. This second step of chemical strengthening allows for ion exchange with high surface stress in the glass composition described in this application, increasing the drop resistance and impact resistance of the chemically strengthened glass. For Na-K chemical strengthening, the lower the temperature, the slower the ion diffusion in the glass, resulting in a lower strengthening layer, higher surface ion concentration, and easier achievement of high surface compressive stress. However, if the chemical strengthening temperature is too low, the ion exchange coefficient of the glass decreases, making it impossible to achieve a usable strengthening layer. If the chemical strengthening temperature is too high, stress relaxation easily occurs, the surface compressive stress decreases, and the salt bath is prone to volatilization and decomposition, leading to impurities adhering to the surface of the glass composition and significantly reducing the salt bath life. Therefore, the second-step chemical strengthening temperature in this application can be selected as 420–520°C, 430–500°C, or even 440–490°C. In some embodiments, the second-step chemical strengthening temperature can be 420°C, 425°C, 430°C, 435°C, 440°C, 445°C, 450°C, 455°C, 460°C, 465°C, 470°C, 475°C, 480°C, 485°C, 490°C, 495°C, 500°C, 505°C, 510°C, 515°C, 520°C, etc., as well as all ranges and sub-ranges between the above values. The shorter the chemical strengthening time, the shallower the strengthened layer and the greater the surface compressive stress. However, if the chemical strengthening time is too short, the strengthening effect will be insignificant, and an effective strengthened layer will not be obtained. If the chemical strengthening time is too long, it can easily lead to stress relaxation, as well as surface damage and surface deposits caused by severe salt bath volatilization and decomposition. Therefore, the glass described in this application is expected to have a lower strengthening time to obtain a larger surface compressive stress and prevent salt bath deterioration. The second chemical strengthening time in this application can be selected from 10 minutes to 2 hours, or from 20 minutes to 2 hours. In some embodiments, the second chemical strengthening time can be 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, 40 minutes, 45 minutes, 50 minutes, 55 minutes, 1 hour, 1 hour 10 minutes, 1 hour 20 minutes, 1.5 hours, 1 hour 40 minutes, 1 hour 50 minutes, 2 hours, etc., as well as all ranges and subranges between the above values.

[0161] During the chemical strengthening process, some Li ions in the glass composition / glass preform are replaced by Na ions and / or K ions, resulting in chemically strengthened glass containing one or both of Na₂O and K₂O. Therefore, the total content of Na₂O and K₂O in chemically strengthened glass (Na₂O + K₂O) is greater than 0 but less than or equal to 6%, and can be selected from 0.1% to 0.5%, or from 0.5% to 3.5%. In some embodiments, the total content of Na₂O and K₂O in the chemically strengthened glass (Na₂O + K₂O) can be greater than 0, 0.01%, 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2%, 2.3%, 2.5%, 2.7%, 3%, 3.3%, 3.5%, 3.7%, 4%, 4.3%, 4.5%, 4.7%, 5%, 5.3%, 5.5%, 5.7%, 6%, etc., as well as all ranges and sub-ranges between the above values. It should be understood that, in embodiments, any of the above ranges can be combined with any other range.
