SINGAPORE – Kulicke and Soffa Industries, Inc. (NASDAQ: KLIC) ("Kulicke & Soffa", "K&S", "we" or the "Company") announced its collaboration with TSMT (Taiwan Surface Mounting Technology Corp), a worldwide leading LCD SMT (Surface Mount Technology) solutions provider, to advance mini LED backlight and direct emissive displays for high-volume adoption.
Mini LED technology in displays is anticipated to increase rapidly over the coming years, providing new opportunities for Kulicke & Soffa's advanced display portfolio. TrendForce, a world leading market intelligence provider, anticipates mini LED wafer shipments will increase at a CAGR of 38%, to over 8M four-inch equivalent wafers, through 2027. During this period, LED die size is expected to be reduced significantly in both backlighting and direct emissive applications, accelerating the transition from more typical semiconductor die-attach approaches, to dedicated advanced display approaches. The Company's dedicated advanced display solutions – PIXALUX™ and LUMINEX™ – support demanding market requirements with new-levels of throughput and high-accuracy placement capabilities. Leveraging these innovative dedicated solutions as well as the collective process knowledge of both K&S and TSMT, this collaboration seeks to overcome today's process challenges to accelerate the mass adoption of advanced display technology.
PIXALUX™ quickly became the largest installed base of ultra-fast dedicated mini LED placement equipment shortly after its 2018 introduction. Today, LUMINEX™ extends K&S leadership by providing a dedicated laser-based mini and micro LED transfer solution that enhances flexibility, yield and productivity for panel and display manufacturers. LUMINEX is designed to transfer small die with high accuracy and throughput.
"We are excited to enhance our long-term relationship with K&S to deliver high-volume manufacturing solutions for mini LED backlighting and direct emissive displays. Through joint efforts, LUMINEX™ has achieved an impressive production throughput of 540K units per hour (UPH) at 15µm 3-sigma accuracy, broadening the market reach for this technology. We are currently working on improving the yield from 99.99% to 99.999%," said John Wu, TSMT's President.
"Our comprehensive advanced display portfolio directly serves the technology needs of major display markets rapidly transitioning to advanced display technology. Key markets transitioning include high-volume televisions, IT displays, as well as both large and small format direct-emissive displays. Today, LUMINEX™ is the most compelling high-volume manufacturing solution for mini-LED transfer and we are extending its capability to micro LED," said Chan Pin Chong, Kulicke and Soffa's Executive Vice President, Products and Solutions.
The throughput of LUMINEX™ is scalable through its various modes of operations – Precision Correction Mode (PCM), Multi-pattern Placement (MPP) and SCAN Mode. In the scan mode, it is capable of throughput of over 30M UPH. While LUMINEX™ is preparing to move into high-volume adoption for mini-LED applications, initial micro LED development results are encouraging and the Company has achieved 4µm 3-sigma accuracy for direct die placement of 40µm x 80µm die. This solution is also suitable for Micro LED in Package (MIP) applications.
