LED Configurations for TVs

Edge vs. Direct vs CCFLs
 Direct LEDs were implemented first and were believed to be the ultimate
winner due to their excellent contrast, black level and power performance.
 However, Samsung shocked the display and TV industry with the launch of
edge-lit LED TVs. Few people was thinking about edge lighting after the
Luminus/GLT approach failed.
 Although edge lighting has trade-offs relative to CCFLs and Direct in power, cost
and contrast, it has the best mix of features and a nice cost reduction roadmap.
12

Edge vs. Direct Share
 Edge to continue to dominate through the forecast, but direct share to
rise as LED prices fall.
 Direct penetration led by the largest sizes.

Edge-lit Cost Reduction Roadmap
 First generation edge-lit designs used as many as 6 LED modules.
 Second generation has already been reduced to 4 with 2 modules
expected in the near future.
 This is occurring due to:
– Larger die reducing total # of die and packaging costs
– More efficient lightguides
– Significant increases in panel transmissivity
– Increases in LED and packaging efficiency
14

LED Backlighting Demand by Application
 LEDs to grow at a 30% CAGR to 100B die led by TVs from 2011.

LEDs in General Lighting
 Determined TAM for LEDs in general lighting by determining the number of
lighting sockets by application – commercial, industrial, residential and outdoor.
Created 3 scenarios – base, bull and bear.
 Over 40% CAGR projected from 2010 to 2020 in base case with # of LED die
rising to 40B.
 In addition to falling costs and power and lifetime advantages, LEDs will also
benefit from incandescent bulbs being phased out around the world and
government national/city subsidy programs. However, long lifetimes will affect
the replacement market leading to some annual declines.

costs all determined by MOCVD
performance.
• MOCVD is also the slowest process in the
fab @ 7-8 hours per run, and is the
largest contributor to yield loss.

MOCVD Trends
 Boosting throughput to meet demand through:
– Larger process chambers
– Larger wafer sizes
– Faster deposition rates
– Minimizing downtime by improving chamber/injector cleanliness.
Eliminating bake step for cleaning
– Improving/implementing automation – robots and loadlocks becoming
more common to maximize runs per day.
 Improving yields through:
– In-situ monitoring of temperature, film thickness and film uniformity
– Improving film and wavelength uniformity, maximizing gas flow
uniformity without complex tuning
– Keeping process chamber/injector clean
– Larger/thicker wafers
– Improving tool to tool and wafer to wafer repeatability

MOCVD Supply/Demand
 Supply forecast assumes no additional tools installed after Q4’10.
 2010 - 760 units are not sufficient to meet demand. 164 additional units needed,
shifted to 2011.
 2011 - 208 tools needed to meet demand plus the 164 from 2009 resulting in 372.
However, due to subsidies in China, an additional 450 tools are expected to be
installed resulting in a forecast of 818 tools.
 2012 – 867 tools necessary to meet demand excluding the non-demand driven
tools in China. Given lower yields and utilization, expect those tools to only
reduce 2012 demand by 120 tools with another 225 installed resulting in nearly
1000 tools.
 2013 – Only 147 tools necessary to meet demand. However, oversupply will likely
lead to lower prices and higher lighting demand resulting in higher than
projected tool volumes in 2013.

Summary
 LED demand is surging led by TVs and general lighting with a 38% CAGR
forecasted between 2009 and 2015.
 MOCVD equipment is the most important tool in the LED line.
 MOCVD shipments are expected to grow by over 4X to 760 tools in 2010, nearly
50% of the cumulative installed base.
 Due to MOCVD equipment subsidies in China and continued strong LED
demand, MOCVD shipments are expected to continue to grow in 2011 and
2012.
 The large growth in MOCVD supply will lead to additional pricing pressure in
the lighting market, boosting LED demand and tool shipments in 2013.
Nonetheless, a significant decline is expected in MOCVD shipments in 2013.
 Veeco and Aixtron should enjoy an impressive 3-year run, unlike in any other
equipment field.
