On January 16, 2026, Yantai Wanhua Electronic Materials Co., Ltd. (hereinafter referred to as Wanhua Electronic Materials) held a "Press Conference on Mass Production of Ethylsilane," where guests including shareholders, industry associations, and core partners in the industrial chain witnessed the achievement of large-scale and stable mass production of high-purity ethylene silane independently developed by Wanhua Electronic Materials. This breakthrough marks another "bottleneck" key technology that my country has overcome in the field of high-end electronic specialty gases.
On the day of the event, the attendees first visited the production plant of Wanhua Electronic Materials Co., Ltd., located in Yantai Development Zone, to gain a close understanding of the complete system and quality control process for the industrial production of silane. Following this, a press conference was officially held at the Westin Hotel.

At the press conference, Wang Yaoxi, Chairman of Wanhua Electronic Materials Co., Ltd., delivered the opening remarks. Wang Yaoxi stated that the company's initial goal was to achieve domestic substitution of key materials for the integrated circuit industry, using silane as a starting point. After arduous exploration from small-scale trials to pilot production and industrialization, the company has ultimately developed a process package with completely independent intellectual property rights and successfully achieved large-scale stable production of high-purity silane in 2025. Wang Yaoxi proposed that Wanhua Electronic Materials Co., Ltd.'s strategy clearly focuses on three aspects: deeply rooted in silane, deepening and strengthening its position; expanding into electronic specialty gases, enriching its product matrix; and building a "one-stop" service platform to develop into a comprehensive electronic gas service provider. The company will continue to be customer-centric and become a trustworthy long-term partner.
▲ Meng Xiangjiu, Secretary-General of Shandong Semiconductor Industry Association
In his speech, Meng Xiangjiu, Secretary-General of Shandong Semiconductor Industry Association, highly praised Wanhua Electronic Materials Co., Ltd.'s mass production achievements: "Silane, as a key material in advanced processes below 14 nanometers, especially in memory chip stacking, has long relied on imports. Wanhua Electronic Materials Co., Ltd.'s achievement of independent mass production is an important step in solving the 'bottleneck' link in the industrial chain." Meng Xiangjiu, combining the recent policy guidance issued by the province, pointed out that Wanhua Electronic Materials' complete practice from technological breakthroughs to industrial transformation and then to market application is a vivid example of the successful connection of the "technology-industry-market" link. Meng Xiangjiu stated that the association will continue to leverage its platform role to support more enterprises in seizing opportunities and jointly enhancing the regional industrial chain's self-controllability.
▲ Chen Gangjun, General Manager of Wanhua Electronic Materials Co., Ltd.
Chen Gangjun, General Manager of Wanhua Electronic Materials Co., Ltd., explained how the company transforms its strategic blueprint into mass production results. He showcased Wanhua Electronic Materials' core advantages through three key figures: "30%+", "4.8N", and "50 tons." These achievements represent the company's relentless pursuit of independent intellectual property rights, its efficient industrial operation system, and the pragmatic and dedicated culture of its team. Chen Gangjun stated that the company will adhere to the basic principles of "safe, stable, reliable, and continuous" supply, supporting customers' most demanding processes with excellent operations, and becoming the most reliable link in the semiconductor industry chain.
▲ Tan Huiming, Vice General Manager of Wanhua Electronic Materials Co., Ltd.
Tan Huiming, Vice General Manager of Wanhua Electronic Materials Co., Ltd., provided an in-depth analysis of the product value and market prospects of silane. Tan pointed out that in the current era where the explosive growth of AI computing power is driving the iteration of advanced processes, silane, with its significant advantages in deposition temperature, rate, and film quality, has become a core material for advanced chip structures such as 3D NAND and FinFET. Facing the strategic opportunities of rapid growth in the global and Chinese markets in the coming years, Wanhua Electronic Materials has made comprehensive preparations and will create value with customers and partners through three major strategies: an integrated "technology + service" model, building a collaborative ecosystem across the industrial chain, and expanding into the global market.
At the conclusion of the press conference, witnessed by the guests, the key leaders jointly launched a ceremony symbolizing achievements and the future, bringing the atmosphere to a climax.
The successful mass production of high-purity silane has solidified Wanhua Electronic Materials Co., Ltd.'s leading technological position in China's electronic specialty gases industry. With the establishment of the Zhuhai Lihua plant and the advancement of its "one-stop" service strategy, Wanhua Electronic Materials Co., Ltd. is steadily moving towards becoming an internationally competitive integrated electronic gas service provider, contributing to the development of new quality productivity and the prosperity of the semiconductor industry in China.
