University of Tokyo Researchers Fabricate Red, Blue, and Green InGaN LEDs on Glass Substrates with Sputtering
LIGHTimes News Staff
June 26, 2014...Researchers from the University of Tokyo have used a sputtering
method transcribing GaN LEDs on glass substrates. The new
fabrication technique may eventually help reduce manufacturing costs
or help develop OLED light panels. The researchers have not yet
measured external quantum efficiency or luminous efficiency for any
single color. The team is currently testing the internal quantum
efficiency at low temperatures.
The researchers note that InGaN LEDs are limited to applications in
small devices because InGaN LED fabrication involves expensive metal
organic vapor phase epitaxy on single-crystal wafers. However, the
researchers successfully employed sputtering, a less expensive
epitaxial growth process, on large-area substrates to fabricate
large-area InGaN LED displays.
The use of multilayer graphene buffer layers allowed the growth of
highly c-axis-oriented GaN films even on amorphous substrates.
The team fabricated blue, red, and green InGaN LEDs. The
researchers believe that their method of sputtering to produce
full-color LEDs on amorphous substrates could be adapted to
fabricate large-area inorganic LED displays on glass substrates.
Already, sputtering is frequently used in the LCD industry.
The researchers point out that advances in the glass industry can
offer roll-to-roll processing of flexible glass foils. Furthermore,
the team contends that a combination of these methods may lead to
the development of large-area flexible inorganic devices.

New 3M LED Chip Packaging Substrate Provides Economical Substitute for Ceramic
LIGHTimes News Staff
June 2, 2014...3M Electronics Materials Solutions Division in Austin, Texas,
launched its new LED Chip Packaging Substrate that provides a
cost-effective alternative to ceramic substrates. The company says
that the new substrate, which combines copper and polyimide,
can meet the thermal and electrical performance that high-power LED
chips need at a competitive price compared to ceramic substrates.
The substrate comes either in a tray or reel format. According to
the company, the reel format will help the industry evolve to
reel-to-reel manufacturing that is expected to lower manufacturing
cost. The company will showcase the chip packaging substrate at
Lightfair International, June 3-5, 2014 in Las Vegas, NV at the 3M
booth (# 4821).
The LED chip can sit directly on top of a large conduit area, which
a polyimide frame holds without adhesives. 3M says that substrate
assembly does not require adhesives. Therefore, the substrate can be
used at higher temperatures. The substrate can
also reportedly work with wire bond and flip chip
“LED chip manufacturers now have an alternative to ceramic
substrates,” said Terry Noronha, global business manager, 3M
Electronics Materials Solutions Division. “3M has harnessed more
than 40 years in the circuit industry and 50 years in light
management to find a new way to move the LED lighting industry
forward. Not only does the 3M substrate meet LED requirements at
reduced cost, but it enables reel-to-reel manufacturing with
precision engineering – what we believe to be the future of
efficient high-volume manufacturing.”

LIGHTimes News Staff
May 28, 2014...Plessey Semiconductors Ltd reported that the company has ordered another
CRIUS II-XL MOCVD system to expand its production capacity for fabricating
Gallium Nitride LEDs on Silicon wafers (GaN-on-Si). The Close Coupled
Showerhead system, which was recently delivered with a 7x6-inch configuration,
will supplement the Aixtron production system that the company already owns.
Dr. Keith Strickland, chief technology officer for Plessey said,
“Our MaGICTM (Manufactured onGaN-on-Si I/C) LED product in particular
has been successfully launched this past year. As a result, we now plan to step
up our production. To this end, and given our positive experience with
Aixtron’s CRIUS II-XL system, we have purchased a further system of this
type and are thus maintaining our successful cooperation with
“CRIUS II-XL convinced us with its high throughput rates and low
operating costs for GaN layer growth on 6-inch silicon substrates. Moreover,
Aixtron is actively supporting us in further optimizing our production
processes," added Mike Snaith, Operations Director for Plessey.
“We are delighted by the renewed order from Plessey," said
Dr. Frank Schulte, Vice President Aixtron Europe. “It offers further
confirmation that Gallium Nitride-on-Silicon, a high-performance, efficient
epitaxy process, is becoming increasingly established as an alternative to
growth on sapphire. The associated potential production cost savings will
further promote the establishment of LED as a light source. Aixtron is well
prepared for this market development and will also be supporting Plessey in
further optimizing its GaN-on-Silicon technology.”
Substrates are Impacting LED Front-end Business, According to Yole Development
LIGHTimes News Staff
May 1, 2014...Market Research Firm Yole Development says that substrates are clearly
impacting LED fabrication throughout the LED industry. "New LED substrate is
one of the key topics impacting the LED front-end industry," said Pars Mukish,
technology & market analyst at Yole Development (Yole). “Substrates
are clearly shaping this industry with the start of the use of Silicon and bulk
GaN as a potential replacement of sapphire," he added.
In Yole Development's latest report about the influence of substrates on the
LED manufacturing business, Pars Mukish explains the need for cost reduction in
LED fabrication and evaluates emerging substrates and related technologies
including GaN-on-GaN LEDs and GaN-on-Si LEDs. Yole says that LED makers have
looked to reduce costs to be competitive with other substrate technologies.
According to Yole, companies are switching to larger size 6" sapphire
wafers, and Taiwanese companies are switching to 4” wafers to be
competitive in terms of the bill of materials. Additionally, companies are
increasing their use of patterned sapphire substrates. Yole says increased
demand for patterned sapphire substrates has made PSS mainstream in the market
(87% share as of Q1-2014). Despite the increased demand, some questions remain
concerning key patent holders’ strategies.
Yole points out that certain companies have developed and have begun mass
production of GaN-on-Si and GaN-on-GaN LEDs. For example, Soraa has begun mass
producing GaN LEDs on bulk GaN substrates, , and Toshiba has begun mass
production of LEDs on silicon.
“However, market penetration of these alternative substrates will
be secondary to future improvements in terms of performance and cost,"
said Pars Mukish indicated that GaN-on-GaN and GaN-on-Silicon LEDs have to
improve in performance and cost to fully compete with sapphire-based LEDs.
Otherwise, GaN-on-Si and GaN-on-GaN LEDs will not be able to fully compete with
Yole notes that GTAT and Apple have partnered to set up a large sapphire
manufacturing plant to produce sapphire components for more rugged smart phone
lenses and screens. Yole expects the impact of the sapphire industry on the LED
industry to become bigger in the future because of the recent partnership
between GTAT and Apple (Q4-2013) to set up a large sapphire production plant
($1 billion). The plant, which has a rough capacity of 2 times the current
qualified sapphire capacity for the entire world market could totally modify
the structure and evolution of the sapphire and LED industries in the next few
