Cascade Microtech Inc. has announced the release of its InfinityQuad, a multicontact probe head capable of probing 3050?m copper, gold and aluminum pads. Built on the company's Infinity Probe technology, the device addresses manufacturing requirements of mixed-signal device in the automotive radar and wireless HDMI markets.

Analog automotive application-specific devices lead the growth segments in the IC industry, according to IC Insights. The firm stated that systems and features such as GPS navigation, anti-roll, and collision-avoidance/adaptive cruise control are expected to help this segment achieve 32 percent growth in 2011. The high-frequency devices found in today's collision-avoidance radar and wireless HDMI are made up of complex mixed-signal integrated circuits containing RF, DC and logic with frequencies of 60 to 80GHz. Up until now, it has been difficult to probe these frequencies on very small pads and deliver accurate measurements.

The new InfinityQuad uses a unique lithographically defined architecture to probe small pads and enable high-frequency test. This probe technology enables customization of up to 25 contacts for ground, power, logic, RF or mm-wave contacts to 110GHz. It enables probing of 3050?m pads at fine pitches over a temperature range of -40 to +125C with minimal pad damage. The InfinityQuad delivers repeatable, accurate measurement of ICs, transistor or device arrays and test structures with low contact resistance on aluminum, copper or gold pads. The InfinityQuad is the only technology that allows automated testing of automotive radar and other devices with multiple mm-wave signals as well as lower frequency signals, power and control lines.

"The unique design of the InfinityQuad allows our customers to stay ahead of the technology curve for testing complex device geometries," said Michael Burger, president and CEO, Cascade Microtech.
