Phil Nyborg, a veteran chief executive officer at two other semiconductor firms, is the new CEO at RTP-based Ziptronix.

Ziptronix is developing chips incorporating three-dimensional integrated circuit (3DIC) solutions. The company is a spinout of RTI International, having launched in 2000. It has raised more than $23 million in venture capital, including $17 million in May of 2003.

“Phil brings an outstanding record of successfully commercializing semiconductor technology and we are thrilled that he is on board,” said Mitch Mumma, a member of Ziptronix’ board of directors and a partner at venture capital firm Intersouth Partners in Durham. “He brings the strategic vision and operating skills needed to drive Ziptronix’ technology into production and establish it as the de facto standard for 3DIC integration.”

Nyborg comes to Ziptronix from JAM Technologies in Boston, where he was CEO. JAM is a producer of digital audio integrated circuits. According to Ziptronix, Nyborg changed JAM’s business model from being a provider of intellectual property into a producer of circuits.

Nyborg also was president and a founder of ONEX Communications, which focused on high-speed integrated ciruits for use in telecommunications.

Doug Milner, the previous CEO, left Ziptronix in January of 2004 after two years in the job. Bill Knapp, the vice president of engineering, had served as CEO on an interim basis, according to The Triangle Business Journal.
