【Standard News】Led 1 Standard, Participated in 2 | Garen Semiconductor Further Advances Gallium Oxide Group Standard Development

      From June 16 to 17, the 2026 China Semiconductor Materials Group Standard Review Meeting (first half of the year) was held in Tianjin. The meeting was organized by the Semiconductor Materials Branch of the China Electronic Materials Industry Association, bringing together authoritative experts, leading enterprises, and research institutions in China’s semiconductor materials sector to conduct centralized reviews of multiple proposed group standards.

      As a leading company in the fourth-generation semiconductor gallium oxide field, Hangzhou Garen Semiconductor Co., Ltd. (hereinafter referred to as “Garen Semiconductor”) led the initiation of the group standard “Zirconia Fiber Thermal Insulation Products for Gallium Oxide Crystal Growth”. The company also actively participated in the development of two additional standards: “Non-destructive XRT Inspection of Defects in Gallium Oxide Materials” and “X-ray Diffraction Method for Twin Content Measurement in Gallium Oxide Materials”. The parallel advancement of these three standards fully demonstrates Garen Semiconductor’s strong sense of corporate responsibility and its commitment to advancing industry standardization.

Focusing on thermal field materials and filling standardization gaps

      Zirconia fiber thermal insulation products are key thermal field materials used in the crystal growth process of gallium oxide. They feature excellent ultra-high-temperature resistance (up to 2400°C), outstanding thermal insulation performance, and high thermal stability without volatilization at elevated temperatures. These properties directly affect temperature gradient control and crystal quality stability during growth.

      The group standard led by Garen Semiconductor will define classification, technical requirements, testing methods, and inspection rules for these products, aiming to establish a unified evaluation framework for thermal field materials and fill a domestic standardization gap in this field.

      In May 2026, Garen Semiconductor signed a strategic cooperation agreement with Shandong Liangji Wendu New Materials Co., Ltd., further strengthening collaboration in materials R&D and thermal field design. The initiation of this group standard represents an important step for Garen Semiconductor in transforming its technical expertise into shared industry resources and promoting coordinated development across the supply chain.

Active participation in standard system development

      In addition to its leading project, Garen Semiconductor is also actively involved in two gallium oxide-related standards.

      The “Non-destructive XRT Inspection Method for Defects in Gallium Oxide Materials”, led by China Resources Microelectronics Co., Ltd., aims to establish a standardized non-destructive defect characterization method based on X-ray topography (XRT).

      The “X-ray Diffraction Method for Twin Content Measurement in Gallium Oxide Materials”, led by Shenzhen Pingshan Laboratory, focuses on twins—a key defect affecting single-crystal quality and device performance—and promotes standardization of measurement methodologies.

      In the development of both standards, Garen Semiconductor leverages its technical expertise in gallium oxide single-crystal growth to provide strong support for the scientific validity and practical applicability of the methods.

Fulfilling leading enterprise responsibility and strengthening industrial foundation

      As a core leading enterprise in the fourth-generation gallium oxide semiconductor field, Garen Semiconductor relies on its in-house production lines and strong independent R&D capabilities. The company has achieved a globally leading technology platform featuring 8-inch gallium oxide substrates and 8-inch homoepitaxial wafers, establishing a full-chain capability covering equipment, crystal growth, substrates, and epitaxy.

      Garen Semiconductor recognizes that leading enterprises must not only drive technological innovation but also take an active role in shaping industry standards. From leading two group standards—“β-phase Gallium Oxide Homoepitaxial Wafer” (T/CEMIA 050-2025) and “Test Method for Dislocation Density in Gallium Oxide Single Crystals” (T/CEMIA 051-2025)—to proposing two national standards, and now advancing a new round of group standards with a “1 leading, 2 participating” structure, Garen Semiconductor continues to contribute its technological strength to the standardization and healthy development of the gallium oxide industry.

      The company will continue to uphold its mission of advancing standard system development and supporting high-quality industrial growth, contributing to a robust and sustainable industrial ecosystem.

      Garen Semiconductor is committed to providing high-quality gallium oxide products and solutions. Its product portfolio includes VB crystal growth equipment dedicated to gallium oxide, commercial 6-inch gallium oxide homoepitaxial wafers, custom substrates for photoconductive switches, and 2-inch (011)-oriented gallium oxide substrates.

      The company warmly welcomes partners across the industry chain to explore cooperation opportunities, jointly expand the application boundaries of gallium oxide in power electronics and optoelectronic devices, and accelerate the transformation of cutting-edge research into industry standards, thereby promoting the high-quality development of the gallium oxide sector.
