What is a quartz wafer?
The biggest feature of quartz wafer is its high chemical purity. Its wafers made of semiconductor grade quartz are widely used in solar energy, industrial applications and thin film coatings.
It is also widely used in semiconductor processing, and its mechanical and optical properties are widely recognized by the public. In general, quartz is a single crystal material with different crystal directions. Typical cutting methods include x cut and y cut,AT cutting, and ST cutting.
In terms of diameter, it can be divided into two inches, three inches and 10 inches. We can also customize the dimensions of other diameters according to the specific requirements of customers.Mosa
we have achieved double-sided polishing. After our experiment was formed, we were afraid that it would be cut into essence and finally polished.
We provide high quality transparent quartz substrates.In terms of thickness, from 0.4、0.5、0.7、1.1 to 3mm.We can provide sizes from one inch to 12 inches, and we also provide chips and packaging compatible with ultrasonic cleaning and cleanroom.
The high-quality transparent quartz substrates | Quartz wafer provided by us include including fused silica wafer and fused quartz wafer in UV grade , optical grade and semiconductor grade . They are widely used in microwave filters, optical lenses and optical fiber applications. They are also widely used in lighting. From the perspective of shape, we can provide circular and square shapes.
The characteristics of synthetic quartz glass substrate include high degree and chemical resistance. It has excellent thermal shock resistance. The quartz glass has chemical inertia to most elements and compounds, heat resistance, high transparency, fluorescence and smooth surface.
Applications of Synthetic Quartz Glass Substrates include photomask substrates in the semiconductor industry, poly-Si-TFT substrates for LCDs, micro lens substrates
for LCDs and fiber optics, substrates for high frequency (RF) applications, microfluidic substrates, Nano-Imprint Templates, and DNA chip substrates.
