SK Hynix to build new chip packaging plant in S Korea

SK hynix Inc. is set to establish a new semiconductor back-end process plant in Cheongju, South Korea.

The company will demolish an existing building at its Cheongju factory site, about 110 kilometers south of Seoul, to make space for the new facility named “Package & Test (P&T) 7.”

The demolition is expected to be completed by September.

Once completed, this will be SK hynix’s seventh P&T plant, joining other sites in South Korea and China.

These plants handle back-end semiconductor processes, which include finalizing chips from processed wafers and packaging them into finished products.

However, the specific purpose of the new facility has not yet been finalized.

🧠 Food for thought

1️⃣ Advanced packaging emerges as new battleground beyond miniaturization

SK hynix’s investment in a new P&T facility reflects a broader industry shift where competition is increasingly focused on packaging innovation rather than just miniaturization.

The global semiconductor back-end equipment market is projected to grow from $113 billion in 2025 to $157.7 billion by 2030, representing a 6.89% CAGR as manufacturers race to develop more sophisticated packaging solutions 1.

This strategic pivot comes as traditional performance gains through process miniaturization have become increasingly difficult and costly, pushing companies to find alternative methods to enhance chip performance and efficiency.

Advanced packaging is particularly crucial for memory manufacturers competing in the high-bandwidth memory (HBM) market, where stacking multiple DRAM chips requires sophisticated technologies to address heat dissipation and warping challenges.

The timing of SK hynix’s investment aligns with industry forecasts showing the semiconductor market growing to $697 billion in 2025, with memory technologies for AI applications being a significant growth driver 2.

2️⃣ Memory makers reposition for AI-driven growth through strategic investments

SK hynix’s expansion of packaging capabilities directly targets the booming AI chip market, where high-bandwidth memory has become essential infrastructure.
