Objective:Objective: Change the rules of display manufacturingChange the rules of display manufacturing Simple interface Reduced system complexity Combined display and electronics manufacturing in one process Improved reliability (fewer interconnections) Non-breakable plastic Result: Reduced cost
Approach:Approach: Conventional silicon foundries to fab circuits Proprietary etching to form silicon NanoBlockTM IC’s Proprietary FSA™ process to distribute NanoBlock IC’s on flexible
substrate Conventional roll-to-roll (web) display manufacturing• .
Alien Technology Flexible Displays
Technical Capabilities
Proprietary, patented process to separate electronics fabrication from display fabrication
Allows Alien to leverage existing foundries
Allows Alien to design display electronics in single crystal silicon
Allows Alien to drive any and all display materials
Permits, for the first time, active electronics on plastic substrates
4 patents issued, 1 allowed, 22 more filed/in process Lowers display factory capital investment from ~$1 billion to under
$100 million
Modular factory capacity increase ($25 million increments)

Conclusion
Alien is not a niche manufacturer... Alien is going after major display markets...A little bigger, a little more resolution, a little more value-added each year... Alien is not inventing, but combining modern manufacturing with IP...Alien has the cost advantages, the features & the IP protection...
Alien has:management experience
sustainable advantagesand scalable manufacturing processes
Alien Technology…….can become the next Intel
