July 3, 2007—Japan’s Sumitomo Precision Products Co. Ltd. has completed the acquisition of Primaxx Inc., an Allentown, PA-based venture-funded manufacturer of MEMS etch release equipment, in an all-cash transaction. Primaxx manufactures reduced pressure, residue-free MEMS dry etch release, a critical buried oxide etch step that “releases” the moving components of challenging MEMS device designs. SPP will continue to maintain Primaxx operations in Allentown and retain all current employees.
Primaxx complements the advanced deep silicon etch and deposition business of Surface Technology Systems, a manufacturer of Deep Silicon Etch technology, in which SPP owns a majority stake.
