Glass Core packaging emerges as AI chips drive shift from wafers to panels

The semiconductor industry is undergoing a structural shift driven by the physical demands of modern AI processors. Traditional 300 mm wafer-based packaging, which has dominated for decades, is increasingly ill-suited to chips that exceed the practical bounds of that form factor. Square panels offer a more efficient geometry for larger die, but the industry cannot rely on a single technology to bridge this transition. The parallel development of glass core, FOPLP, and CoPoS suggests manufacturers are hedging their bets while the market sorts out which approach will deliver both performance and manufacturability. For glass core specifically, Manz Asia's emphasis on yield underscores a hard economic reality: a novel packaging technology, no matter how promising, is worthless at scale if it cannot be produced reliably and cost-effectively. Yield—the percentage of functional units from a production run—is the metric that separates viable manufacturing from laboratory success.
