A iteração tecnológica das máquinas de moagem de bolachas de silício está a acelerar e as realizações inovadoras de muitas empresas estão concentradas na aterragem
May 20, 2025 - Recently, China's semiconductor equipment field has made a series of breakthroughs in the silicon wafer grinding process. The new single-crystal silicon wafer grinder developed by Ai Pang Semiconductor Technology (Sichuan) Co., Ltd. has achieved a production efficiency improvement of more than 30% through the alternating operation design of double grinding frames, and the use of buffer components effectively reduces the risk of silicon wafer edge damage. At the same time, the double-sided grinder integrated with dust collection device launched by Chengdu Qingyang Electronics solved the problem of grinding dust pollution of traditional equipment. Its synchronous double-sided grinding technology can optimize the surface roughness of silicon wafers to nanometer level.
Anhui Ge Nan Machinery focuses on environmental protection needs. Its grinding waste liquid filtration equipment achieves a 99.7% removal rate of large particle impurities in waste liquid through a multi-stage treatment system, providing the industry with green production solutions. Experts pointed out that these innovations indicate that domestic equipment is upgrading from single processing to the full-chain technology system of "precision grinding-waste recycling".
Market data shows that with the accelerated expansion of companies such as Sany Silicon Energy, China's annual silicon wafer production capacity is expected to exceed 80 billion pieces in 2025, and the demand for high-precision and low-loss grinding equipment will continue to increase. The popularity of third-generation semiconductor materials such as silicon carbide has further promoted the development of double-sided grinding technology towards ultra-thinness and intelligence. At present, the R&D investment of leading companies accounts for more than 15% of revenue, and the localization rate of core components has increased by 40 percentage points compared with 2020.
