Through the acquisitions of Cambridge Nanotech’s atomic layer deposition solutions and IBM’s patents for packaging, we have extended our market reach and solidified our technology leadership. With the introduction of four new laser processing products - LSA101LP, LSA101HP, LSA201LP, and LSA201HP - and our Superfast 3G CGS Inspection System, we have leveraged our existing technology to broaden our product portfolio and enter new and exciting markets.”

“In 2013 we look forward to building upon this momentum as we ramp sales of our new products, expand our leadership position and continue to deliver strong financial performance and value to our shareholders. We believe these objectives are achievable with the dedication and loyalty of our employees and customers worldwide," Zafiropoulo concluded.
