about us

Introduction of Hangzhou Haiqian Semiconductor Co., Ltd.

      Hangzhou Haiqian Semiconductor Co., Ltd. is a high-tech enterprise focusing on the R&D, production and sales of the third-generation semiconductor silicon carbide epitaxial wafers.

      Haiqian has a senior technical team in the industry, most of the team members have more than 11 years of experience in the semiconductor industry, based on years of technical precipitation and rich experience in the industry. The team has mastered the world wide leading silicon carbide epitaxial wafer mass production technology. Haiqian adheres to the "quality shapes the future" for the purpose and strives to contribute to the development of the third generation semiconductor industry.

      Haiqian Semiconductor started the construction of first-phase plant in September 2022. Twelve international advanced 6 inch silicon carbide epitaxial production lines have been put into operation since September 2023. The throughput of qualified 1200V MOSFET grade epitaxial wafers has reached 3,900 pieces per month and 46,800 pieces per year. The second-phase plant has started construction of production workshops containing 120 high-quality 6/8 inch silicon carbide epitaxial reactors in May 2023,which can supply more than 510,000 high-quality 1200V grade epitaxial wafers per year.

      Haiqian adheres to the business philosophy focusing on technology-centered, quality-based and customer satisfaction-oriented. Haiqian provides customers with high-quality product supply and value-added services and provides employees a broad space for self-development. We create wealth for the industry with the fruits of our labor.

  • Double laser precise defect scanning

    The chip defect scanning and detection equipment of Haiqian Semiconductor has adopted dual laser scanning technology, which not only accurately detects the morphology defects on the crystal surface, but also accurately scans and detects the lattice defects inside the material.

  • Self developed process flow to ensure high yield

    The production processes of Haiqian semiconductor epitaxial wafers are independently developed, achieving high yield while being independently controllable, without any issues of being stuck.

  • Innovative mass production technology for preventing device failure

    In addition to conventional measurement and control methods, Haiqian Semiconductor has added special control methods to ensure that mass-produced silicon carbide epitaxial wafers will not fail due to abnormal epitaxial material quality. This technology is an original creation of Haiqian Technology Team.

  • High uniformity epitaxial technology

    After a series of process optimizations and equipment upgrades, the Haiqian Semiconductor Technology Team has achieved an epitaxial layer thickness non-uniformity of less than 0.5% for silicon carbide epitaxial wafers and a carrier concentration non-uniformity of less than 1.5% for epitaxial layers.

  • Low defect density control technology

    The Haiqian Semiconductor Technology Team relies on years of epitaxial process experience and current technological development to continuously optimize and iterate its own silicon carbide epitaxial technology. At the same time, it develops substrates from different manufacturers, and epitaxial growth on substrates from different manufacturers can achieve low defect density, providing strong guarantee for device reliability.
