Business environment

Semiconductor manufacturers have shown caution in

assessing economic impact of Japanese earthquake on

their supply chain and end-product markets

Although direct impact to the electronics industry world-

wide seems limited, it has caused some of our customers

to review their existing equipment delivery and order plans

Resulting adjustments are only affecting potential litho

system demand above what is currently the analyst’s

consensus

We continue to expect a total revenue level for 2011 clearly

above €

5 billion

/ Slide 12

Device complexity drives litho opportunity due to a 

growing number of critical litho layers
