Qualcomm and Samsung invested $8 million in Shanghai-based chip equipment maker Advanced Micro-Fabrication Equipment (AMEC) on Wednesday, closing last October’s $35 million Series B investment led by Walden International, Lightspeed Venture Partners, and Interwest Partners.

The investment is part of Qualcomm’s commitment it made in 2003 to invest up to $100 million in early to mid stage Chinese companies.

AMEC is developing manufacturing technologies and equipment for 65-nanometer and 45-nanometer chips, the most advanced processes currently available or under development by its competitors. Smaller chips increase performance and use less energy by preventing power leakage.

Some chips, such as Intel’s latest microprocessors, are manufactured using a 65-nm process. But most chipmakers are still using a 90-nm process technology.
