Taiwan’s Unimicron Seeks Up to $1.4bn as AI Lifts Chip-Substrate Makers
The circuit-board and substrate supplier is tapping the market at a moment when anything attached to the AI build-out can raise money cheaply.

Unimicron Technology is planning to raise as much as $1.4bn through a sale of global depositary shares, joining the growing list of companies capitalizing on investors’ enthusiasm for AI-related ventures. The Taiwanese firm is offering 50 million shares at a price range of $26.96 to $27.76 each, which represents a discount of approximately 3% to 6% compared to its recent closing price in Taipei, according to Bloomberg. This type of funding opportunity is only feasible in a market where AI chip development has significantly boosted valuations across the supply chain.
Unimicron, while not a household name for most consumers, plays a crucial role in the complex web of the semiconductor industry. It specializes in manufacturing printed circuit boards and IC substrates, which connect chips to these boards—an essential yet often overlooked component as processors become larger and more intricate. As chipmakers advance towards advanced packaging techniques, the substrate becomes a critical element, no longer an afterthought.
The link between Unimicron and AI lies in the high-end packaging modules that power today’s most powerful accelerators. These modules require substrates of superior quality, driving demand for Unimicron’s products. The company’s planned use of proceeds is relatively unglamorous—to source raw materials in foreign currencies—but it reflects the practical reality of manufacturing input costs.
The decision to offer global depositary shares instead of a full foreign listing is strategic. It allows Unimicron to reach international investors while maintaining its primary listing in Taiwan, and raising in US dollars helps offset currency mismatches for a company that buys significant raw materials in foreign currencies.
Timing is crucial here. Taiwanese semiconductor suppliers have witnessed their share prices soar due to AI-driven capital inflows, and Unimicron’s move to raise funds during this favorable market window follows similar actions by memory suppliers. However, there is a word of caution: as sentiment shifts, the window may close, leaving companies wishing they had acted earlier.
