On September 14, 2023, the first national integrated circuit and photovoltaic quartz materials industry development conference was grandly held in Lianyungang City, Jiangsu Province. At the meeting, Song Bo, deputy mayor of Lianyungang Municipal Government and secretary of the Donghai County Party Committee, fully affirmed and provided professional guidance for the future development of the integrated circuit and photovoltaic quartz material industries. Zhang Qibing, deputy secretary of the Donghai County Party Committee and county magistrate, also spoke actively at the opening ceremony of the conference and had high hopes for the entire industry chain. At the warm invitation of the organizer of the conference, our general manager Liu Yingquan was also honored to participate in the conference.

   An integrated circuit is a miniature electronic device or component. Using a certain process, the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit are interconnected, made on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a tube shell , becoming a micro structure with the required circuit functions; all the components in it have structurally formed a whole, making electronic components a big step towards miniaturization, low power consumption, intelligence and high reliability. It is represented by the letters "IC" in circuits. The inventors of the integrated circuit are Jack Kill by (germanium (Ge)-based integrated circuits) and Robert Noyce (silicon (Si)-based integrated circuits). Most applications in today's semiconductor industry are silicon-based integrated circuits.

  Quartz materials for photo lataics are widely used in high-tech silicon material fields such as integrated circuits and photovoltaics due to their excellent properties such as high purity, high temperature resistance, low thermal expansion, and strong chemical stability. They are irreplaceable in the development of national strategic industries and pillar industries. of high-purity basic materials. In the integrated circuit chip manufacturing process, quartz materials are used as devices required for semiconductor etching, diffusion, oxidation and other processes. It is estimated that for every US$100 million of electronic information products produced, an average of US$500,000 worth of high-purity quartz material is consumed. In the field of photovoltaics, high-purity quartz materials are mainly used as consumable auxiliary materials such as quartz crucibles and diffusion furnace tubes. In recent years, global photovoltaic installed capacity has continued to rise, and the demand for high-purity quartz materials in the photovoltaic industry has also grown rapidly.
