Epistar Corp (晶電), the nation’s leading LED chip manufacturer, yesterday announced it is taking aim at the growing micro-LED display industry, saying that over the next one to two years the next-generation chips would start to be used in virtual and augmented reality devices and wearables.
“We are confident, as Epistar and Osram Licht AG are the only two companies in the world that are capable of simultaneously producing red, green, and blue LED, an essential capability in the development of self-luminous micro-LED displays,” Epistar chairman Lee Biing-jye (李秉傑) told reporters before the company’s annual general meeting in the Hsinchu Science Park.
Over the next two years, micro-LED technology will start to be used in devices such as wearables and smartphones, while in three to five years it would be employed in larger devices such as TVs, Lee said.
The technology is expected to start generating significant revenue for Epistar in five years because penetration rates and shipments would take time to grow, Lee said.
Epistar is reportedly co-developing the technology with Apple Inc at a plant in Taoyuan’s Longtan District (龍潭).
Epistar does not give specific information about its clients, Epistar president M.J. Chou (周銘俊) said, but added that it is collaborating with more than one client to develop micro-LED technology.
The development of micro-LED displays involves epitaxial wafers and chips, mass transfer technology and bonding technology, Chou said, adding that the company’s main focus is on producing the epitaxial products.
Epistar is focusing research and development on the development of mass transfer technology, which is important in the fast and accurate mounting onto a display of large numbers of micro-LED chips, Chou said.
“We think that there is potential for micro-LED technology to become the future of the LED industry if it becomes used in smartphones, because every year around the world tens of millions smartphones are shipped,” Chou said.
He declined to disclose the scale of Epistar’s investment in the technology.
Epistar is positive about the company’s business outlook next quarter on increasing orders for the blue/white LED chips used in lighting products and four-element LED products, Chou said.
Citing clients’ order forecasts, Chou said that overall demand for blue/white LED chips has outstripped supply, but added that the situation might change after Chinese peers expand production capacity in the fourth quarter.
Epistar continues to increase the added-value of its products and improve its product portfolio and operational efficiency in an effort to swing its operations back into the black this year, he said.
Epistar last year reported a net loss of NT$3.54 billion (US$116.18 million at the current exchange rate), or NT$3.33 per share.
With this year’s Semicon Taiwan trade show set to kick off on Wednesday, market attention has turned to the mass production of advanced packaging technologies and capacity expansion in Taiwan and the US. With traditional scaling reaching physical limits, heterogeneous integration and packaging technologies have emerged as key solutions. Surging demand for artificial intelligence (AI), high-performance computing (HPC) and high-bandwidth memory (HBM) chips has put technologies such as chip-on-wafer-on-substrate (CoWoS), integrated fan-out (InFO), system on integrated chips (SoIC), 3D IC and fan-out panel-level packaging (FOPLP) at the center of semiconductor innovation, making them a major focus at this year’s trade show, according
DEBUT: The trade show is to feature 17 national pavilions, a new high for the event, including from Canada, Costa Rica, Lithuania, Sweden and Vietnam for the first time The Semicon Taiwan trade show, which opens on Wednesday, is expected to see a new high in the number of exhibitors and visitors from around the world, said its organizer, SEMI, which has described the annual event as the “Olympics of the semiconductor industry.” SEMI, which represents companies in the electronics manufacturing and design supply chain, and touts the annual exhibition as the most influential semiconductor trade show in the world, said more than 1,200 enterprises from 56 countries are to showcase their innovations across more than 4,100 booths, and that the event could attract 100,000 visitors. This year’s event features 17
EXPORT GROWTH: The AI boom has shortened chip cycles to just one year, putting pressure on chipmakers to accelerate development and expand packaging capacity Developing a localized supply chain for advanced packaging equipment is critical for keeping pace with customers’ increasingly shrinking time-to-market cycles for new artificial intelligence (AI) chips, Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) said yesterday. Spurred on by the AI revolution, customers are accelerating product upgrades to nearly every year, compared with the two to three-year development cadence in the past, TSMC vice president of advanced packaging technology and service Jun He (何軍) said at a 3D IC Global Summit organized by SEMI in Taipei. These shortened cycles put heavy pressure on chipmakers, as the entire process — from chip design to mass
Germany is to establish its first-ever national pavilion at Semicon Taiwan, which starts tomorrow in Taipei, as the country looks to raise its profile and deepen semiconductor ties with Taiwan as global chip demand accelerates. Martin Mayer, a semiconductor investment expert at Germany Trade & Invest (GTAI), Germany’s international economic promotion agency, said before leaving for Taiwan that the nation is a crucial partner in developing Germany’s semiconductor ecosystem. Germany’s debut at the international semiconductor exhibition in Taipei aims to “show presence” and signal its commitment to semiconductors, while building trust with Taiwanese companies, government and industry associations, he said. “The best outcome
