Samsung plans to spend $1.9 billion on a new chip plant in Korea.
The plant will churn out mobile processors to meet growing demand for tablets and smartphones.
The new line will use 300mm wafer and 20nm and 14nm production technology, Reuters reports.
At the moment Samsung's most advanced Exynos chips, like the Exynos 4 quad of Galaxy S III fame, rely on the 32nm process. Even the upcoming Exynos 5 dual, based on ARM's next generation A15 core will stick to 32nm.
Samsung recently announced plans to construct a massive NAND plant in mainland China, at a purported cost of between $3.4 and $4.2 billion.
