cascade_infinityquadMulti-Contact Probe for 30 um x 50 um Device Pads

21 October 2011 — Cascade Microtech announced InfinityQuad, the only multi-contact probe head capable of automatically probing aluminum, copper or gold pads as small as 30 µm x 50 µm. The InfinityQuad probe uses a patented technology to address cutting-edge mixed-signal device manufacturing requirements in emerging markets such as automotive radar and wireless HDMI.

Analog automotive application-specific devices lead the growth segments in the IC industry, according to a recent report by IC Insights stating systems and features such as 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 60-80 GHz. Up until now, it has been difficult to probe these frequencies on very small pads and deliver accurate measurements.

The new InfinityQuad probe uses a unique lithographically-defined probe tip 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 110 GHz, and enables probing of 30 µm x 50 µm pads at fine pitches over a temperature range of -40 to +125°C 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 probe is the only probe technology that allows automated testing of automotive radar and other advanced devices with multiple mm-wave signals as well as many 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, Inc. "As the market moves to smaller and smaller footprints for high-frequency test, precision measurement becomes critical. Cascade Microtech is pleased to offer our customers a truly innovative, high-performance multi-contact probe solution to meet the challenges of device test today and in the future."
