SAN JOSE -- Numerical Technologies Inc. today said it has completed its acquisition of design software supplier Cadabra Design Automation Inc., which is expected to help accelerate mainstream use of phase-shifting mask technology. At the time of the announced acquisition, the stock purchase was valued at $130 million (see Sept. 5 story).
"As the industry continues to follow Moore's Law deeper into the subwavelength realm, it's not enough to incorporate phase-shifting technology into photomask manufacturing and the lithography process," said Y.C. (Buno) Pati, president and CEO of Numerical Technologies. "IC design and layout must also change to leverage the benefits of phase-shifting technology."
Pati said the combination of combining products, technologies, and expertise from Numerical and Cadabra will enable his company to address the needs of mainstream chip manufacturing and accelerate adoption of its phase-shifting technology. The use of phase-shifting photomasks enables existing lithography tools to print feature sizes smaller than the wavelength of exposure light. As a result, expensive steppers and scanners can be used longer and next-generation deep-submicron chips can be introduced sooner.
According to Numerical Technologies, the merger will significantly increase the number of ICs produced using its phase-shifting technology. Last year, Numerical Technologies rolled out its iN-Phase software to extend the use of 248-nm lithography systems (see May 3 story).
Faysal Sohail, former president and CEO of Cadabra, joins Numerical senior vice president of worldwide technology licensing and sales. He will oversee technology licensing, product sales and field applications engineering. Martin Lefebvre, founder of Cadabra and former chairman and chief technology offier, is also joining Numerical. Lefebvre has become a member of Numerical's office of the chief technology officer (CTO) and will be responsible for integrating Numerical's technology with Cadabra's products.
