Quartz plates play a crucial role in the semiconductor industry, serving as one of the key raw materials for manufacturing semiconductor chips. They are widely utilized not only in semiconductor manufacturing but also in the photovoltaic industry and liquid crystal display manufacturing. This article will detail the application of quartz plates in the semiconductor industry.

1. Semiconductor fabrication

Quartz plates are primarily used as substrates in semiconductor manufacturing, providing the foundation for wafer growth. Semiconductor wafers are essential components of electronic devices. During the manufacturing process, various materials are deposited on these quartz substrates and subsequently processed to produce final products. Quartz plates exhibit excellent chemical stability, thermal stability, and optical properties, which meet the stringent requirements of semiconductor manufacturing. Additionally, the surface smoothness and optical characteristics of quartz plates significantly influence the quality of semiconductor chips.

2.Photoetching field

Photoetching technology represents a pivotal process in the realm of semiconductor manufacturing, with quartz plate constituting a primary material in the fabrication of lithography masks. The formation of a pattern on the surface of the semiconductor is enabled by the optical properties of the photoresist, thereby facilitating the fabrication of the device. Quartz plates boast high optical transparency, mechanical strength and chemical stability, which makes them ideal for the lithography process. This ensures the successful application of lithography technology in the semiconductor manufacturing industry.

3. Ion implantation

Ion implantation is a pivotal process in the manufacture of semiconductors. It involves the injection of various impurities into semiconductor wafers to regulate the conductive and other properties of semiconductor materials. In the ion implantation process, quartz is used as the target for impurity injection. This ensures the stability and accuracy of the injection process, and in turn, the quality and performance of semiconductor wafers.

4. Cleaning process

Semiconductor manufacturing processes require multiple stages of cleaning of the semiconductor wafers to ensure a consistently reliable production process. In the cleaning process, quartz plates can be used as cleaning vessels, pipes or cleaning media. This ensures the cleanliness and stability of the process. The quartz plate itself exhibits high corrosion resistance and chemical stability, making it suitable for the treatment of various cleaning solutions.

5. Other applications

In addition to the aforementioned applications, quartz plates play a crucial role in several key industries, including photovoltaics, liquid crystal display manufacturing, and laser technology. In the photovoltaic sector, quartz plates serve as substrates for silicon wafers, facilitating the growth of silicon crystals essential for solar cells. In liquid crystal display manufacturing, quartz plates function as the foundation for liquid crystal materials and optical transparent materials, aiding in the preparation of liquid crystal display substrates. In laser manufacturing, quartz plates are utilized as substrates for laser optical components, used for mirrors and optical lenses of lasers.

Overall, quartz plates are indispensable raw materials in the semiconductor industry. Their superior properties and versatile applications ensure smooth semiconductor manufacturing processes and enable extensive use across other fields. As the semiconductor industry continues to advance and technology progresses, the application scope and demand for quartz plates will steadily increase, providing critical support for the development of the semiconductor industry.
