FormFactor unveils 300-mm TouchMatrix probe card for NAND Flash devices

FormFactor has unveiled the TouchMatrix probe solution, a 300-mm full-wafer contact probe card for NAND Flash devices. This TouchMatrix probe card is designed for cost sensitive test flows and enables testing of Flash devices down to sub 32-nm process nodes, including those integrating three-bit and four-bit memory cell architectures.

TouchMatrix cards utilize FormFactor's MicroSpring technology that provides low noise and stable contact resistance enabling reliable testing of small Flash device architectures and ensuring high-test yield. The MicroSpring contacts are manufactured using semiconductor lithography processes, making them high scalable to Flash manufacturers' roadmaps as they migrate to small device features. FormFactor's self-cleaning MEMS probe tips also require less maintenance.

The TouchMatrix solution features an architecture that improves the efficiency and reduces the delivery lead-time for the TouchMatrix probe card and determines the type and volume of product to ramp at a given time. The TouchMatrix architecture does not require the full wafer map to initiate production. Probe card repair is also made easy, where the card can be disassembled and reassembled without planarity or x/y position adjustments.

The TouchMatrix probe card is designed for improved thermal performance that enables to quick reach and maintains test temperatures, improving throughput and extending uptime. The card can also be enhanced with FormFactor's RapidSoak technology to achieve near-zero soak time and better scrub performance.

"While under enormous manufacturing cost pressures, Flash memory manufacturers must test each device to ensure its functional performance and quality," stated Adrian Wilson, general manager of the Flash Business Unit at FormFactor. "Our Flash customers need innovative solutions that can lower their cost of test and this was the focus and goal of our TouchMatrix solution. Cost and performance are equally important to them. Our TouchMatrix solution provides superior electrical and probe contact performance, and its new architecture also has the benefit of manufacturing efficiency, which allows us to pass savings along to our customers."

Availability: Now in qualification testing at several Flash device manufacturers and are available for shipping.
