【Member News】Powerhouse Collaboration, Opening New Horizons丨Shandong Extreme Temperature and Hangzhou GAREN SEMI Forge Deep Strategic Partnership

      On the afternoon of May 13, Shandong Extreme Temperature New Materials Co., Ltd. (hereinafter “Shandong Extreme Temperature”) and Hangzhou GAREN Semiconductor Co., Ltd. (hereinafter “GAREN SEMI”), a leading core enterprise in the fourth-generation semiconductor gallium oxide (Ga₂O₃) sector, officially signed a deep strategic cooperation agreement, with the signing ceremony successfully concluded.

      Building on years of collaboration, both parties reached a consensus on key topics including industrial development, technology iteration, and coordinated layout. With this strategic upgrade as a milestone, Shandong Extreme Temperature will no longer serve merely as a supplier of thermal-field products, but will become a close partner with GAREN SEMI in jointly establishing a “materials–thermal-field” collaborative R&D system. This integration will leverage Shandong Extreme Temperature’s advantages in zirconia-based thermal insulation materials—such as high-temperature stability, thermal-field uniformity, and ultra-low thermal conductivity—together with Hangzhou GAREN’s R&D and mass-production capabilities, achieving true synergy from “supporting” to “co-evolving.” This collaboration is expected to drive the expansion of Ga₂O₃ production capacity, technological iteration, and deeper industrial coordination.

      This marks a significant step in the rapid rise of the Ga₂O₃ industry, as domestic key consumables and core processes move from “cooperative support” toward “strategic co-evolution.”

Defining Industry Standards through Global Breakthroughs

Hangzhou GAREN SEMI

      As a leading force in the gallium oxide (Ga₂O₃) field, GAREN SEMI has consistently pushed the boundaries of R&D, redefining the global benchmark for technological innovation in the Ga₂O₃ industry. In 2025, the company successfully developed the world’s first—and to date, only—8-inch Ga₂O₃ substrate, completely breaking the longstanding technological monopoly. At the same time, GAREN SEMI became the first to integrate the full Ga₂O₃ industry chain, from single-crystal growth and precision processing to epitaxial fabrication. Multiple key performance indicators have reached world-class levels, establishing the company as a core engine driving the global Ga₂O₃ industry forward.

Completing the Critical Puzzle of the Industry Chain with Core Materials

Shandong Extreme Temperature

      The large-scale production of high-quality Ga₂O₃ single crystals heavily relies on a precise, stable, and ultra-pure thermal environment tailored to the process. Leveraging its long-term expertise in zirconia-based thermal insulation materials, Shandong Extreme Temperature has built formidable technical barriers and continues to serve leading companies across industries, with its products’ critical value in the semiconductor sector well established.

      This upgraded collaboration not only represents a powerful alliance across the upstream and downstream of the industry chain but also signifies a deep integration of “key consumables” with “core processes.”

Building a Closed-Loop Collaboration to Drive the Industry Ecosystem

      The two parties will establish a deep collaborative mechanism, using frontline process data to continuously inform materials R&D and systematically address the common challenges of thermal field adaptation that constrain industry expansion. This initiative will directly accelerate cost reduction, efficiency improvement, and large-scale production in the Ga₂O₃ industry, injecting strong momentum into trillion-yuan downstream markets such as new energy vehicles, photovoltaic energy storage, and smart grids.

      From “collaborative support” to “strategic symbiosis,” Shandong Extreme Temperature, leveraging its core technological capabilities, is joining hands with industry leaders to jointly write a new chapter of independent and controllable development in China’s fourth-generation semiconductor industry.
