LG Innotek eyes top spot in FC-BGA substrate market

Supply shortages of the high-density semiconductor substrates are expected to continue through 2027

South Korea’s LG Innotek Co. will boost the production of its flip chip ball grid array (FC-BGA) packages, or high-density package substrates, "to a meaningfully high level” from the second half of this year, its Chief Executive Jeong Cheol-dong said.

“We will increase our share in the FC-BGA market to 30% or more within the next few years and become No. 1 player in the sector,” he told The Korea Economic Daily last Saturday on the sidelines of CES 2023 in Las Vegas.

To that end, the camera module maker will make aggressive investments to mass produce sophisticated semiconductor substrates so as to crack the market dominated by Japanese rivals. 

Jeong is upbeat about its FC-BGA business, saying it would take less than 10 years for the company to take the lead in the sector. 

“Despite being a latecomer, we will upend the market, where Japanese companies control 60%,” he said. "The FC-BGA market has huge growth potential. We’ll make it our key revenue source.”

An FC-BGA is used to produce semiconductor modules, on which memory chips, a central processing unit and a graphic processing unit are assembled. They employ state-of-the-art technologies for smaller circuits and layer build-ups.

The high-performance substrate is called the Hermes of the semiconductor sector because of its high price tag.

The market is now controlled by a handful of companies such as Japan’s Ibiden Co. and Shinko Denki Co. and Taiwan’s Unimicron.

LG Innotek has been spending 413 billion won ($331 million) to build FC-BGA facilities since last year. During CES 2023, it displayed its FC-BGA prototypes.

“We’ve already secured a major customer,” Jeong said. “We will speed up efforts to increase our customer base.”

LG Innotek is not alone in pushing into the FC-BGA market. Its domestic rival Samsung Electro-Mechanics Co., and Taiwanese and Chinese competitors are also rushing to secure their footholds in the segment.

An industry official said that CPU manufacturers such as Intel Corp. and AMD Inc. recommended substrate makers to boost FC-BGA output. 

Chip designing companies are now seeking to buy FC-BGAs even before they hit the market, he added. 

Supply shortages of FC-BGAs are expected to continue through 2027, driven by the growth in artificial intelligence and cloud server markets.

Apple Car, an electric vehicle under development, is expected to adopt the FC-BGA.
