SAN FRANCISCO—Ultratech Inc., a supplier of lithography and laser-processing systems used to manufacture semiconductors, said Thursday (June 28) it acquired the rights to a collection of chip packaging patents from IBM Corp. The purchase price was not disclosed.
The acquired patents include fundamental packaging such as C4 bumping, ball grid arrays, lead-free solders and 3-D packaging, Ultratech (San Jose, Calif.) said. The portfolio includes U.S. and foreign patents, the firm said.
Arthur Zafiropoulo, Ultratech's chairman and CEO, said in a statement that Ultratech has periodically purchased patents it views as key to its business.
