 Cadence Design Systems has acquired Invarium, a DFM pattern synthesis specialist, for an undisclosed amount. The acquisition is seen as a further move by major EDA companies to boost their DFM offerings for designs targeted at the 45nm node and below.
"Invarium's layout-to-mask solution is in use by manufacturers of custom and memory designs at advanced process nodes, where the highest level of accuracy and widest process latitudes are required," said Roy Prasad (pictured), President and CEO of Invarium. "Augmenting the Cadence design-side DFM leadership with Invarium's manufacturing technology will allow us to provide global customers a comprehensive DFM solution, from design implementation through silicon signoff and manufacturing."
"At 45 nanometers and below, the semiconductor industry is looking at a new set of patterning challenges that include double patterning, printability and scaling of very fine features, and the margin for error is extremely small," said Jim Miller, Executive Vice President of Products and Technologies Organization for Cadence. "The acquisition of Invarium will enhance Cadence's ability to address these challenges head-on."
Invarium had only recently boosted its sales and marketing efforts with the addition of Wolfgang Straud, who left Cadence for the DFM start-up. Dr. Chris A. Mack, ‘Lithography Guru and Gentleman Scientist,' had accepted a role as advisory scientist to the company.
