| INCREASE IN ANALOG PRODUCTION CAPACITY |
|
TI recently purchased more than 100 tools from Qimonda North America and Qimonda Dresden, Germany as the first step in launching the Phase II expansion of RFAB, the industry’s first 300-mm analog wafer fab, located in Richardson, Texas. When complete, Phase II of RFAB will double the analog manufacturing capacity in the facility, bringing its revenue capability to about $2 billion. The Phase II expansion will give TI a head start in providing our customers access to significant analog capacity to fuel their growth.
