SK Hynix Inc is ramping up its spending on advanced chip packaging, in hopes of capturing more of the burgeoning demand for a crucial component in artificial intelligence (AI) development: high-bandwidth memory (HBM).
The Icheon-based firm is investing more than US$1 billion in South Korea this year to expand and improve the final steps of its chip manufacture, said Lee Kang-wook, a former Samsung Electronics Co engineer who now heads up packaging development at SK Hynix.
Lee specializes in advanced ways of combining and connecting semiconductors, which has grown in importance with the advent of modern AI and its digestion of vast troves of data via parallel processing chains. While SK Hynix has not disclosed its capital expenditure budget for this year, the average analyst estimate puts the figure at 14 trillion won (US$10.5 billion). That suggests advanced packaging, which could take up a 10th of that, is a major priority.

“The first 50 years of the semiconductor industry has been about the front-end,” or the design and fabrication of the chips themselves, Lee said in an interview. “But the next 50 years is going to be all about the back-end,” or packaging.
Being first to achieve the next milestone in this race could now catapult companies into industry-leading positions. SK Hynix was chosen by Nvidia Corp to provide the HBM for its standard-setting AI accelerators, pushing the South Korean firm’s value up to 119 trillion won. Its stock gained about 1 percent in Seoul on Thursday, adding to a nearly 120 percent increase since the start of last year. It is now South Korea’s second most valuable company, outperforming Samsung and US rival Micron Technology Inc.
Lee, now 55 years old, helped pioneer a novel method to packaging the third generation of the technology, HBM2E, which was quickly followed by the other two major makers. That innovation was central to SK Hynix winning Nvidia as a customer in late 2019.
HBM is a type of high-performance memory that stacks chips on top of one another and connects them with through-silicon via (TSV) technology for faster and more energy-efficient data processing.
ChatGPT’s release in November 2022 was the moment Lee had been waiting for. By that time, his team had developed a new packaging method called mass reflow-molded underfill (MR-MUF), aided by his contacts in Japan. The process, which involves injecting and then hardening liquid material between layers of silicon, improved heat dissipation and production yields. SK Hynix teamed up with Namics Corp in Japan for the material and a related patent, a person familiar with the matter said.
SK Hynix is pouring the bulk of its new investment into advancing MR-MUF and TSV technologies, Lee said.
Samsung, which has for years been distracted by a succession saga at its very top, is now fighting back. Nvidia last year gave the nod to Samsung’s HBM chips, and the Suwon-based company said on Feb. 26 that it has developed the fifth generation of the technology, HBM3E, with 12 layers of DRAM chips and the industry’s largest capacity of 36 gigabytes.
On the same day, Boise, Idaho-based Micron surprised industry watchers by saying it had begun volume production of 24GB, eight-layer HBM3E, which would be part of Nvidia’s H200 Tensor Core units shipping in the second quarter.
With its big commitment to expanding and enhancing technology at home and a multibillion-dollar advanced packaging facility planned for the US, Lee remains bullish about SK Hynix’s prospects in the face of intensifying competition. He sees the present investment as laying the groundwork to meet more demand to come with future generations of HBM.
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday said that its investment plan in Arizona is going according to schedule, following a local media report claiming that the company is planning to break ground on its third wafer fab in the US in June. In a statement, TSMC said it does not comment on market speculation, but that its investments in Arizona are proceeding well. TSMC is investing more than US$65 billion in Arizona to build three advanced wafer fabs. The first one has started production using the 4-nanometer (nm) process, while the second one would start mass production using the
A TAIWAN DEAL: TSMC is in early talks to fully operate Intel’s US semiconductor factories in a deal first raised by Trump officials, but Intel’s interest is uncertain Broadcom Inc has had informal talks with its advisers about making a bid for Intel Corp’s chip-design and marketing business, the Wall Street Journal reported, citing people familiar with the matter. Nothing has been submitted to Intel and Broadcom could decide not to pursue a deal, according to the Journal. Bloomberg News earlier reported that Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) is in early talks for a controlling stake in Intel’s factories at the request of officials at US President Donald Trump’s administration, as the president looks to boost US manufacturing and maintain the country’s leadership in critical technologies. Trump officials raised the
‘SILVER LINING’: Although the news caused TSMC to fall on the local market, an analyst said that as tariffs are not set to go into effect until April, there is still time for negotiations US President Donald Trump on Tuesday said that he would likely impose tariffs on semiconductor, automobile and pharmaceutical imports of about 25 percent, with an announcement coming as soon as April 2 in a move that would represent a dramatic widening of the US leader’s trade war. “I probably will tell you that on April 2, but it’ll be in the neighborhood of 25 percent,” Trump told reporters at his Mar-a-Lago club when asked about his plan for auto tariffs. Asked about similar levies on pharmaceutical drugs and semiconductors, the president said that “it’ll be 25 percent and higher, and it’ll
CHIP BOOM: Revenue for the semiconductor industry is set to reach US$1 trillion by 2032, opening up opportunities for the chip pacakging and testing company, it said ASE Technology Holding Co (日月光投控), the world’s largest provider of outsourced semiconductor assembly and test (OSAT) services, yesterday launched a new advanced manufacturing facility in Penang, Malaysia, aiming to meet growing demand for emerging technologies such as generative artificial intelligence (AI) applications. The US$300 million facility is a critical step in expanding ASE’s global footprint, offering an alternative for customers from the US, Europe, Japan, South Korea and China to assemble and test chips outside of Taiwan amid efforts to diversify supply chains. The plant, the company’s fifth in Malaysia, is part of a strategic expansion plan that would more than triple
