Wushi Microelectronics Raises $14.9M Series A

Wushi Microelectronics has raised $14.9 million in a Series A round to scale its wafer bonding tools, according to Dealroom.

The financing gives the semiconductor equipment maker fresh capital at a moment when demand for advanced packaging and bonding technology is rising across the chip supply chain. Wafer bonding — the process of joining semiconductor wafers or dies into a single structure — has become a critical step in producing 3D-stacked chips, advanced sensors and memory devices.

Dealroom reported the round but did not name the participating investors, disclose a valuation or detail the intended use of proceeds. Series A funding at this scale typically supports product development, manufacturing capacity and early customer deployment.

Wushi Microelectronics develops wafer bonding equipment, a category of capital tools that chipmakers and packaging houses rely on to build multi-layered device architectures. As chipmakers push beyond traditional planar scaling, bonding tools have moved from a niche process step to a central enabling technology for high-bandwidth memory, CMOS image sensors and heterogeneous integration.

The $14.9 million check size places Wushi Microelectronics among a cohort of Chinese semiconductor equipment startups attracting venture capital as the country's domestic chip tool sector expands. Beijing has made localizing semiconductor manufacturing equipment a policy priority, and investors have followed with funding for companies across lithography-adjacent, deposition, etch and bonding segments.

The round signals continued investor appetite for semiconductor hardware despite a broader slowdown in venture funding across other sectors. Equipment makers with defensible process technology and qualified customers have remained attractive targets because demand tracks fab construction and capacity expansion rather than consumer electronics cycles.

Wushi Microelectronics has not disclosed how the new capital will be deployed. If the company follows the pattern of peers in the bonding equipment segment, the funding would likely support tool development, pilot production and qualification with domestic fabs — a process that can take a year or more per customer but tends to lock in long-term supply relationships once completed.

The company's next test will be converting its Series A capital into qualified production tools and repeat orders from chipmakers.
