MicroSense Acquires SigmaTech

June 14, 2012

The acquisition adds leading-edge wafer inspection tools to MicroSense’s portfolio of metrology products.

LOWELL, MA /PRNewswire/ -- MicroSense LLC, a worldwide leader in high-resolution capacitive position sensors, metrology modules, and high-sensitivity magnetic metrology tools, announced the acquisition of SigmaTech Inc., of Tempe, AZ. SigmaTech has developed award-winning, high-sensitivity metrology tools for LED, MEMS, and semiconductor manufacturing. With this acquisition, MicroSense adds leading-edge wafer inspection tools to its portfolio of innovative metrology solutions. SigmaTech systems integrate multiple sensing technologies, such as optical spectrometry, interferometry, and SigmaTech's patented auto-positioning back pressure technology. MicroSense will integrate its capacitance sensors into SigmaTech metrology platforms.

"This acquisition makes excellent sense as it marries our leading capacitance sensing technology with SigmaTech's field-proven, highly reliable metrology platform to provide highly stable and repeatable wafer metrology systems for targeted applications," according to James Pelusi, Chairman and CEO of MicroSense. "SigmaTech's customers and prospects will continue to be supported by the existing SigmaTech employees, all of whom will stay with the combined business, and will also benefit from the additional resources, infrastructure, and the decades of metrology experience that MicroSense will bring to the business."

"We are excited to join the MicroSense team as their high-resolution capacitive sensor technology provides an ideal path to increasing throughput of our metrology systems and expanding the field of applications," said Jacques Fauque, semiconductor industry veteran and founder of SigmaTech, who will remain with the business and continue to lead its development.
