According to reports, Samsung Electronics is ramping up construction efforts at its Pyeongtaek Campu' Fourth Complex (P4), with work on Phase 2 (PH2) and Phase 4 (PH4) expected to begin in earnest during the second half of this year. According to industry reports, external construction worth approximately KRW 7 trillion (around USD 5 billion) is set to officially commence soon.
Construction orders for PH2 and PH4 have already been issued, with major groundwork anticipated to begin within two to three months. Insiders revealed that while formal construction is scheduled for November, preparatory work could start as early as September.
Originally, Samsung intended for PH2 and PH4 to be dedicated foundry production lines. However, in light of the recent downturn in foundry demand, the company has reconsidered its strategy. PH2 is now under internal review for potential conversion into a hybrid facility that could support a mix of DRAM, NAND, foundry, and advanced packaging operations. Discussions are ongoing about whether PH2 will serve as a DRAM-focused fab or be optimized for multi-functional semiconductor manufacturing. PH4, currently planned as a DRAM production line, is still in its final construction phase, with no immediate production activity confirmed.
Meanwhile, progress on PH1 and PH3 continues steadily. PH1, initially intended as a dedicated NAND flash facility, has evolved into a hybrid plant that will produce both NAND and fourth-generation (1a) 10nm-class DRAM. Equipment installation for PH1 is nearing completion. PH3, also designated for DRAM production, began receiving production equipment starting in June.
The Pyeongtaek P4 complex is a cutting-edge semiconductor hub composed of four development stages—blending both memory and logic manufacturing capabilities. Samsung's phased approach initially prioritized PH1 for memory, followed by PH2 for logic, then PH3 for memory, and finally PH4 for logic, representing one of the most ambitious chip production infrastructures in South Korea.
