strengthened its next-generation semiconductor tools line with the acquisition Thursday of privately held Invarium.

Terms of the acquisition, announced Thursday, were not disclosed.

Invarium, founded in 2003, gives Cadence additional "mask manufacturing"tools capabilities for integrated circuits at 45 nanometers and below. Both companies are based in San Jose, Calif.

Shares of Cadence were recently off 4 cents to $21.61.

Invarium's DimensionPPC technology solves some of the process challenges as semiconductor features shrink to ever smaller dimensions.

In April, Invarium reported that one of the top 10 semiconductor tools designers had begun to deploy its technology. With annual revenue of $1.5 billion, Cadence is one of the largest providers of IC design tools.
