16 LEDS IN DISPLAYS Traditional SMD or CSP packaged LEDs are commonly used as the illumination source for the backlighting of LCD panels. LEDs are also commonly used in large direct emissive video billboards used in stadium, advertising and video facades. In those devices, discrete packaged LED containing red, green and blue chips form the individual pixels with pitches typically ranging from 1 to 40 mm depending on display size and resolution. Packaged LEDs are commonly used in large video displays and LCD backlight. MicroLEDs could be at the center of a new display revolution As of Q1-2017, there is no other format of commercial displays using LEDs as a direct emissive element to constitute individual pixels or sub-pixels. The reasons for this limitation are multiple and include cost and manufacturability. Nevertheless, the idea of µled displays with high resolution and sub millimetric pixel pitch is almost as old as the invention and commercialization of LEDs themselves. Over the last 3-4 years it has generated a lot of excitement and development as well as investment and M&A activity. Packaged LED LED Video display Illustration: 16

17 MICROLED APPLICATION ROADMAP Now (2017) Soon) (2-3 years) Mid term (3-5 year) Longer term (>5 years) or out of reach? Small pitch (<2 mm) large video displays. Brings significant performance improvement (contrast) and potential cost reduction (eliminates LED package) Large die OK (30 µm) but low transfer efficiency.

18 LEADING PATENT HOLDERS 140+ players have filed patents related to microled.the 500+ microled inventions are held by a lot of different patent applicants. Some players have filed their own patents (XXX, XXX, XXX, XXX, XXX, XXX, XXX, XXX, XXX, XXX, XXX ), while other ones have acquired IPs through patent licensing agreements (XXX, XXX, XXX) or M&A (Apple/LuxVue, Oculus/InfiniLED). Many R&D Labs are present in the microled patent landscape (University of Illinois, ITRI, CEA-LETI, CIOMP, Fraunhofer, Sejong University ). * A patent family is a set of patents filed in multiple countries by a common inventor(s) to protect a single invention.

20 MicroLED DISPLAY ASSEMBLY The art of making µled displays consists in processing a bulk LED substrate into an array of micro-leds which are poised for pick up and transfer to a receiving substrate for integration into heterogeneously integrated system: the display (which integrates, LEDs, transistors, optics etc ). The micro-leds can be picked up and transferred individually, in groups, or as the entire array of 100,000 s of µleds: MicroLED chips can be singulated and transferred individually or as large monolithic arrays. Massively Parallel Transfer ( Pick and Place ) Individual µled dies or small chips comprising small amounts of µled emitters (<10) are singulated and individually picked up, transferred, positioned and assembled to a backplane containing the pixel driving circuitry (typically TFT on glass or flexible substrate). The pitch on the display is typically lower than that of the donor wafer. µled chips Arrays Monolithic Integration Large chips comprising large quantities of µled emitters (>10,000 s to millions) are hybridized onto a backplane (typically Si CMOS). Individual pixels are not physically singulated. The pitch of the donor array matches the pitch of the display. µled array Backplane Epiwafer or carrier with pre-singulated die Transfer Tool Backplane Hybridization Display Backplane Epiwafer 20

21 BACKPLANE AND PIXEL BANK STRUCTURE Backplane Frontplane The TFT backplane can be essentially identical to that of an OLED display all the way through the planarization layer. The front plane structure including the interconnects and the pixel banks can be built directly upon the backplane. The bank layer thickness and angle can be used to adjust the display viewing angle. µled dies are positioned into the pixel bank by the transfer tool and connected by solder reflow or other processes. More than 1 µled of the same color can be placed in each bank if redundancy is required to mitigate risks of dead/malfunctioning pixels (see Defect Management section of this report) Drain Bank layer Electrode to pixel Passivation Channel (semiconductor) Gate Insulator Gate (metal) Gate Insulator (Dielectric) Light Source Bottom electrode Backplane substrate (Glass, metal, plastic) Cross section of a microled display subpixel Sub pixel Transparent electrode Passivation Planarization Layer (Also known as Interlayer Dielectric: ILD) Other circuitry (not detailed): switch transistors, compensation transistors, capacitors, Subpixel bank Simplified top view of the pixel bank Pixel bank 21

23 PICK AND PLACE PROCESSES Dozens of transfer technologies have been proposed. The major technology options identified by screening more than 450 are shown here Die Stabilization and release: How to provide enough force to hold the die onto the donor wafer but allow its release to the pick up heads Release Die Selection: The pitch of the µleds on the donor wafer is usually smaller than that on the display. Some die need to be picked up while others remain on the donor wafer Die Pick Up: Provide enough force to overcome the bonding force of the die to the donor wafer to allow pick up. Die Placing Provide enough force to overcome the bonding force of the die to the transfer array and drop it off on the receiving substrate Stabilization Donor wafer Donor wafer Donor wafer Display backplane 23

24 KEY IP HOLDERS AND CONCLUSION More than 20 companies have patented massively parallel transfer processes for µleds. Many more processes could be inferred by combining the different technology bricks described in this section. Main patent applicants involved in massively parallel pick and place technology (according to the number of their patent families*) Mass transfer is a cornerstone of µled display technologies. Luxvue and X- Celeprint have solid IP portfolio on the topic. Most are probably just concepts that haven t yet reached the stage of prototypes. None has yet been fully validated in volume production to the exception of the PDMS stamp process developed by the team of Prof. Rogers at the University of Illinois and used by startup Semprius for photovoltaic applications. X-Celeprint is developing and commercializing the technology for µleds and other micro-devices. Beside X-Celeprint, the most advanced company in the field of massively parallel transfer of µleds is likely to be Apple via its acquisition of Luxvue in We believe their the technology to be more complex (MEMS vs polymer stamp) but deliver higher throughputs and be capable of handling smaller size of µleds. Both companies however remains secretive about actual performance of their technology. Another issue not developed in this report is that of the transfer equipment which must ensure very high positioning accuracy at both the pick up and drop off steps. Multiple patents describing transfer tools have been filed by XXX, XXX, XXX etc. Source: * A patent family is a set of patents filed in multiple countries by a common inventor(s) to protect a single invention. 24

25 DEFECT MANAGEMENT STRATEGIES Added epi cost Added epi cost Illustrations: reducing die size to a level where redundancy becomes cost effective, i.e. when decrease in repair cost offsets epiwafer cost increase. The graph shows our simulation for various applications of the epiwafer cost thresholds and corresponding die size at which redundancy becomes cost effective For displays with high pixel counts and pixel density, pixel repair dominates the transfer cost. Pixel redundancy becomes efficient if die size can be reduced. Die size $XX Die size $XX $XX $XX Die size Die size 25

29 MOCVD REQUIREMENT Assuming displays realized with XX x XX µm size µleds, about XXx multiwafer (Veeco s Epik 700 type) or XXX single-wafer reactors would be needed to supply Apple needs. If the µled size can be reduced to XX x XX µm, the numbers drop to XX and XX respectively. Note however that those numbers assume a production run rate averaged throughout the year. Higher numbers (+20~30%) would be needed to absorb the higher run-rates typically experienced in the few the months preceding a product launch.
