SK-1300 Glass Wafer Features
1. High purity:
SK-1300 Glass Wafer uses high-purity synthetic fused quartz material, which is much purer than materials produced by traditional direct methods. This high purity property enables it to effectively reduce impurity contamination during semiconductor manufacturing and improve chip yield and performance stability. For example, in the photolithography process, high-purity wafers can avoid photolithography defects caused by impurities and ensure accurate pattern transfer.
2. Low hydroxyl content:
The hydroxyl content of this wafer is extremely low, less than 200ppm. Low hydroxyl content helps improve the optical performance of the wafer, especially the transmittance in the ultraviolet region. This is critical for semiconductor manufacturing that requires high-precision optical measurement and photolithography processes, ensuring uniform exposure and precise patterning of photoresists.
3. Excellent thermal stability:
The thermal expansion coefficient of SK-1300 Glass Wafer is only 5.5×10⁻⁷, which is much lower than that of ordinary glass materials. This low thermal expansion coefficient enables it to maintain dimensional stability during high-temperature processing and reduce deformation and cracks caused by thermal stress. For example, during the high-temperature diffusion and annealing process of semiconductor chips, the wafer can remain flat, ensuring the smooth progress of subsequent processes.
4. High hardness:
The Vickers hardness of this wafer reaches 55, which has high wear resistance and scratch resistance. In the semiconductor manufacturing process, the wafer needs to be handled and processed many times. High hardness can effectively prevent scratches and damage on the surface of the wafer, extend the service life of the wafer, and reduce production costs.
5. High density:
The density of SK-1300 Glass Wafer is 2.2g/cm³. This high density property gives it good mechanical strength and stability. In semiconductor manufacturing, high-density wafers can better withstand mechanical stress during processing, reduce damage caused by vibration and impact, and ensure the smooth progress of the production process.
6. Low Poisson's ratio:
The Poisson's ratio of this wafer is 1.1, which means that the lateral deformation of the wafer is small when subjected to external force. This feature is very important in semiconductor manufacturing, especially in lithography and etching processes, which can ensure the precise alignment and transfer of patterns and improve the yield and performance consistency of chips.
7. High strain point and annealing point:
The strain point of SK-1300 Glass Wafer is 1700°C and the annealing point is 1060°C. These high-temperature characteristics enable it to maintain good mechanical and optical properties in high-temperature environments, and are suitable for semiconductor manufacturing processes that require high-temperature processing, such as high-temperature diffusion and annealing.
8. Customized service:
This product supports customization and can provide wafers of different sizes (2/3/4/5/6/8/12 inches or customized sizes) and different surface treatments (DSP, SSP, DSL) according to customer needs. This customized service can meet the specific needs of different customers and improve the market competitiveness of products.

Packaging and Transportation
The packaging should be able to withstand the impact, vibration, stacking and extrusion that may be encountered during transportation, while also it has to easy to load, unload and handle.
We use professional wafer box packaging. The wafer box is protected by a double layer bag, the inside is a PE bag that can be dust-proof, and the outside is a aluminum foil bag that can be isolated from the air. The two-layer bags are vacuum-packed.
We will choose carton models according to different sizes of products. And between the product and the carton filled with shock-proof EPE foam, play a comprehensive protection.
Finally choose air transport to reach the customer's hands. This allows customers in any country and region to receive the product in the fastest time.
We comply with the Material Safety Data Sheet (MSDS) rules to ensure that the products transported are free of harmful substances and will not cause environmental pollution and explosion and other possible hazards.
