Against the backdrop of rapid development in the global semiconductor industry, the importance of silicon dioxide materials in chip manufacturing is becoming increasingly prominent. As the most commonly used insulating material in semiconductor devices, silicon dioxide plays an indispensable role in the manufacturing process of integrated circuits.
In chip manufacturing, silicon dioxide is mainly used to form gate oxide layers and interlayer dielectrics. Its excellent insulation performance and thermal stability ensure the reliability and performance of the transistor. With the continuous reduction of chip manufacturing processes, the quality requirements for silicon dioxide films are also increasing. At present, advanced process chips require the thickness of silicon dioxide films to be controlled within a few atomic layers, and the uniformity to reach the sub nanometer level.

Recently, a domestic semiconductor material company has successfully developed ultra-high purity electronic grade silicon dioxide, with a purity of 99.9999%, fully meeting the requirements of 5nm and below processes. This breakthrough broke the monopoly of foreign enterprises and provided important support for the development of China's semiconductor industry.
However, as the chip manufacturing process enters the 3nm and below node, the limitations of traditional silicon dioxide materials begin to emerge. Therefore, researchers are exploring new high-k dielectric materials to replace traditional silica. But experts say that silicon dioxide will remain an indispensable key material in semiconductor manufacturing for a considerable period of time in the future.
Market data shows that the global market size of silicon dioxide for semiconductors will reach 2 billion US dollars in 2022, and is expected to exceed 3 billion US dollars by 2025. With the rapid development of emerging technologies such as 5G and artificial intelligence, the demand for high-performance chips will continue to grow, which will further drive the development of the silicon dioxide material market.
