Jinhong Gas: Electronic-grade dichlorosilane successfully completed trial production
Jinhong Gas issued an investor relations activity record announcement stating that electronic-grade dichlorosilane is the core planned product of the company's convertible bond-funded project, "New High-end Electronic Special Materials Project." Currently, the product has successfully entered the trial production stage, and the project is expected to have an annual production capacity of 200 tons after reaching full capacity. The company is making every effort to promote the testing, certification, and subsequent implementation of this product by semiconductor clients.
In the semiconductor industry, nitrous oxide is typically used as a deposition dielectric material in key thin-film deposition processes; high-purity carbon dioxide is mainly used in cleaning technologies and immersion lithography. To date, the company's nitrous oxide and high-purity carbon dioxide have been successfully adopted by some leading semiconductor companies, and the company will continue to work towards adopting them with high-quality semiconductor clients.
Qinghe Crystal and Tiantong Technology join forces to pave a breakthrough in the high-end development of piezoelectric heterogeneous integration.
In a landmark move to accelerate innovation in the post-Moore’s Law era, Qinghe Crystal and Tiantong Jingmei (a subsidiary of Tiantong Technology, global leader in piezoelectric materials) have entered a deep strategic collaboration to pioneer piezoelectric heterogeneous integration.
Combining Tiantong Jingmei’s world-class piezoelectric single crystal and wafer technologies with Qinghe Crystal’s proprietary low-damage surface activation and high-precision bonding processes, the partnership bridges the critical gaps between materials, equipment, and application development — solving long-standing industry bottlenecks.
Together, they are building a fully integrated value chain:
Piezoelectric Crystal → Wafer → Heterogeneous Integration Equipment → Functional Thin-Film Wafer
The collaboration aims to significantly improve yield, performance, and stability of next-generation piezoelectric devices for 5G/6G RF systems, high-frequency MEMS, medical ultrasound, and quantum sensors while establishing core IP and manufacturing standards.
This is the first end-to-end industrial alliance of its kind in China, setting a new benchmark for cross-domain synergy in advanced semiconductors. The partners will establish a joint R&D center to drive commercialization and position China at the forefront of globally competitive, independent piezoelectronics.
