LED packaging companies have emerged in time in what could be simplistically summarized as 4 waves:

• 1st wave: The technology pioneers which developed GaN chips and white LED technologies through the 1990’s are usually referred to in theindustry as the big 5.

• 2nd wave: A large group of LED companies later appeared in Taiwan composed of start ups leveraging technologies developed by the IndustrialTechnology Research Institute (ITRI) as well as existing optoelectronic components manufacturers leveraging on their existing competences andinfrastructure to enter the high brightness LED business.

• 3rd wave: After year of R&D and strong IP activities, both LG and Samsung invested massively in LED chip and packaging capacity in order topartially supply internal needs for LCD TV backlight and positioning themselves for future growth in the lighting business.

• 4th wave: The strong focus on energy and technology in the China’s 12th 5-year plan made vast amount of subsidies available in order to develop astrong LED supply chain from chips to systems.This resulted in the emergence of 100’s of new LED packaging and luminaire companies.

Smart lighting will provide a further boost to lighting applications.

We expect “planned obsolescence” to become part of the luminaire maker strategy in consumer application.

LED Market Trends - General Lighting

STATUS OF THE LED INDUSTRY

• General lighting will drive LED demand.

• Strong penetration in outdoor and architectural lighting.

• Accelerating penetration in residential lighting.

• Better prospects than initially expected for LED as replacement of fluorescent tubes.

• Better prospects than expected in industrial lighting.

• Socket saturation won’t occur as fast as initially anticipated!

• Models usually assumed that because of the long lifetime of LEDs, the market will saturate once the majority of the light sockets havebeen converted… BUT:

• Actual lifetime is not as long as initially anticipated: 20,000-25,000 hours (or less) rather than 50,000 to 100,000 hours (initially quoted bythe industry).

• Smart lighting will trigger obsolescence in some markets.

• The availability of efficient, cheap and versatile light sources (LED) will increase the average consumption of artificial light per capita.

Overall utilization rate stands at 74% in Q3-2016 after Epistar decreased its capacity.

GaN MOCVD Capacity Supply vs. Demand Trends

LED EPITAXY CAPACITY TRENDS

Highlights:

Wafer consumption dropped significantly in Q3- and Q4-2015 but recovered rapidly in the first half of 2016 and reached record high inearly Q3. We expect demand to show some seasonal weakness in Q4 as LED makers adjust their inventory but not at the scaleexperienced in 2015.

Capacity increase over the last 12 months reflects mostly process efficiency improvement and new reactor procurement at San’an.However, not all reactors have been started yet

More and more packaged LED manufacturers moving to module level!

Vertical Integration - Module Level

RECENT TRENDS IN THE PACKAGED LED INDUSTRY

• Packaged LED manufacturers master LED binning strategy which represent a strong competitive advantage for LED lighting moduleassembly.

• Process manufacturing variability creates multiple binning of LED parameters: Color control / Flux control /VF control.

• Good binning strategy helps to select the LEDs for:

• Reaching the product specification.

• Guarantying the supportability.

• Minimizing the stocks.

• Control of LED production allows to stabilize value at module level using variable LEDs.

While a dedicated supply chain has emerged, sapphire filaments are often produced from rejected LED wafers.

Manufacturing Process (1/2)

LED FILAMENT

• The filament substrates typical dimension is: 30 (L) * 0.8 (W) * 0.4 to 0.8 (thickness) mm.

• They were initially cut with wire saws from 2” sapphire wafers (in many cases, reject from production for LED substrates).

• As demand increased, a dedicated supply chain emerged: many suppliers now start from a rectangular brick which is then sliced intoindividual window blanks before double side polishing. Laser cutting has replaced diamond wire saws.

• The filaments are then assembled onto a lead frame to facilitate subsequent processing for the manufacturing of the COB-typefilament (silver electrode metallization, die attach, interconnect, phosphor coating…).

Compared to MESA and vertical structures, Flip Chip LED can offer advantages toward reliability and lifetime, luminous output, package size and manufacturing cost.

Benefits (1/2)

FLIP CHIP LED

• Flip Chip (FC) LED manufacturing process use (in most case) a gold-tin eutectic direct bonding method where the chip is “stuck” onto the package substrate.

• Such structure of package allow for several features compared to MESA and vertical LEDs which have some unavoidabledisadvantages, such as faulty wire weld, surge strike, insufficient resistance to high current, bond wire breakage caused by the thermalexpansion and contraction of packaging silicone, yield affected by bond wire in manufacturing process (…).

• Nichia has developed a CSP architecture to enable light output only on top of the LED contrary to other LED manufacturers.

• It allow to place the LEDs close to each other on the PCB because there is no side emission of the light and therefore no mutual absorption of light.

• Gap between LED can be reduced to 0.2mm compared to 1mm for conventional CSP LEDs.

• Following Nichia statement, there is no color shifting contrary to other CSP LEDs.

Differences in CSP Architectures / Packages

CSP LED

Difference between Nichia and conventional CSP architecture

Source: Nichia

• Seoul Semiconductor has developed its own CSP architecture that is simpler than conventional CSPdesign since there is no ceramic substrate.

• WICOP (Wafer Level Integrated Chip on PCB) is designed to directly connect the chip to the PCB as thereis no intermediate substrate.

• As the LED chip is directly connected onto the PCB, hence its thermal dissipation channel is especiallyshort, and has low thermal resistance. As a result, the driving current is double that of the average LEDpackage.

• Even if there are some differences between CSP LED manufacturers in the architecture of the “package”,all CSP LEDs have no need for main parts such as package or wire bonding.

For both GaAs-based and Sapphire-based LEDs, wafer bonding enables improved thermal, electrical and/or optical properties.

Introduction (2/2)

WAFER BONDING

• In such designs (i.e.:VTF and TFFC LEDs), Sapphire is replaced by another carrier that offers higher thermal conductivity:

• Silicon-based LEDs involve also the transfer to a silicon carrier (i.e.: bonding step) and removal of the original Siliconsubstrate. Indeed, unlike Sapphire which is transparent, Silicon re-absorbs most of the light emitted toward the substrate.This significantly decreases the efficiency of the LED. The most common solution to the problem is to use a vertical LED structure:

• Regarding GaN-based LEDs (i.e.: GaN-on-GaN LEDs), no wafer bonding process is required.

LLO is the most common substrate removal technique used for volume manufacturing. However, IP constraints, cost, performance limitations and damage caused to the epilayer provide incentive for the development of alternatives.

Other Techniques

SUBSTRATE REMOVAL

• We have identified 3 new techniques for substrate removal but current performance (development status) are not sufficient yet todirectly compete with LLO.

Technique Developer Comments

Chemical Mechanical

PlanarizationASTRI

• The process uses standard grinding and polishing combined with “polish stops”

structures made of hard material embedded into the structure to protect the

epi layers.

• Potentially, multiple wafers can be processed in batch.Also, there is less patent

issues than for LLO. And an increase of yield in terms of reverse current

specification can be achieved compared to LLO.

Electrochemical EtchingYale

University

• Substrate removal technique based on the creation of a nanoporous layer of

GaN using an electrochemical etcher. Further nitride layers are then grown. A

new substrate can then be applied to the top of the structure and the growth

substrate removed at the weakened nanoporous region.

Mechanical TransferNTT

• NTT has developed a technique for growing high-quality layered BN thin films

on sapphire substrates, and also growing high-quality GaN-based thin films on

BN. Since in this structure the cleavable BN plays the role of a release layer, one

can easily detach the GaN-based thin-film devices from the sapphire substrates

and transfer them to the other substrate.

• White light from packaged LEDs is generated by combining blue photons from LED chips with photons of other colors from phosphor material(s).However, as phosphors are mostly produced as powders, LED manufacturers have to blend it the encapsulant to suspend the phosphor powderand allow for simple deposition onto the blue LED chip.

• Many encapsulating materials are available on the market with a wide variety of physical and performance characteristics. LED packagers evaluateperformance of such materials along optical, mechanical, chemical and thermal metrics (with some figures of merit bearing more importance tothe overall package performance than others).

• Additionally, they have to make sure that such material will have the best fit with the phosphor used.

• Below are presented key parameters to consider for encapsulant and potential associated interactions with phosphor materials.

Phosphor quantity can vary significantly from one type of package to another.

On-Chip Configuration - Overview

PHOSPHORS

• Downconverters are usually mixed with a binder (Silicone, Epoxy) and deposited on the device. Alternatively, they can be in a ceramicform or embedded into a solid-state binder that is paired with phosphor chips afterwards (e.g.: glass).The major types are:

Silicates were developed as an alternative to YAG and will lose ground as YAG IP falls into public domain.

Material / Compositions - Focus on Silicates

PHOSPHORS

• M2SiO4:Eu2+ (M=Ba, Sr, Ca) phosphors were originally studied in the 60’s.

• Compositions for LEDs silicate phosphors and the associated intellectual property has beenasserted by a group called the BOSE consortium, consisting of Tridonic, LeuchtstoffwerkBreitungen (LWB) and Litec (now part of Merck) all assignees on the fundamentalUS6809347 silicate patent. The consortium later added Toyoda Gosei which extended theclaims.

• The BOSE consortium later signed a cross licensing agreement with Intematix. Attempt bythe consortium to trademark the name BOSE for phosphors was denied after a complaintby electronic audio company Bose.

• Other companies like GE and Osram also own some IP on silicate phosphors for LEDs.

• Compositions have been developed to cover the green and red portions of the spectra,from 500 to more than 610 nm. However, thermal quenching and chemical instability areoften issues for the most extreme wavelength.

• Significant progress has been made on those aspects. Various types of coating have beenused to improve stability and performance have improved on a continuous basis.Performance of the best silicates are now approaching those of Yellow/Green YAGphosphors. However, those higher performance silicates come at a cost premium.

• Yellow silicates are being quickly displaced by YAG. Green silicates remain used in displayapplications. Orange silicates offer a cheaper alternative to some nitride for mid power LEDwhere photon flux and operating temperature are not too high.
