On December 23, "Weidao Nano," a portfolio company invested in by Junlian Capital—the sub-fund backed by the mother fund managed by Yuanhe Chenchun—was listed on the STAR Market, with stock code: 688147.

Founded in 2015, Weidao Nano focuses on Atomic Layer Deposition (ALD) technology and is primarily engaged in the research, development, manufacturing, and sales of advanced micro- and nanoscale thin-film deposition equipment. The company provides cutting-edge thin-film deposition systems, along with complementary products and services, to customers across various downstream industries. Its business spans semiconductor-related fields such as integrated circuits, photovoltaics, LEDs, and MEMS, as well as the rapidly growing flexible electronics sector. Notably, Weidao Nano became the first domestic Chinese company to successfully deploy a mass-produced High-k ALD system—specifically tailored for 28nm node integrated circuit manufacturing—in an actual production line. The overall performance and key process metrics of its equipment have reached international benchmarks, effectively filling a critical gap in China’s semiconductor equipment landscape.

Since its establishment, Weidao Nano has continuously built and strengthened its technological barriers in cutting-edge fields such as atomic layer deposition reactor design technology, high-throughput vacuum coating technology, advanced process gas control technology for vacuum coating equipment, nano-laminated thin-film deposition techniques, high-quality film manufacturing technologies, process equipment energy control systems, and ALD-based efficient battery technologies. Building on these achievements, the company is further deepening its technical expertise in ALD applications for next-generation photovoltaic cells, integrated circuits, and advanced storage solutions—providing customers with a broader range of premium thin-film deposition products.

Leveraging the core competitive advantages of ALD technology, Weidao Nanomaterials has earned widespread recognition from several renowned solar cell manufacturers, including Tongwei Co., Ltd., LONGi Green Energy Technology, JA Solar Technology, Trina Solar, and Tianhe Solar Energy.
