## Significant milestones

[edit]

In 2003, UTAC established its wholly owned Shanghai operations in Waigaoqiao – a free trade zone in Shanghai. It also formed an alliance with Amkor Technology Inc. in China, combining the strengths of both companies to create a powerful turnkey assembly and test supplier capable of supporting as well as Integrated Device Manufacturers looking to service their end customers in the China market. This partnership was further enhanced in 2007 when both companies announced that they had entered into a multi-year cross-licensing agreement under which Amkor would license its MicroLeadFrame patents to UTAC, and UTAC would license its QFN patents to Amkor. The agreement covers the license of intellectual property rights and transfer of associated packaging technologies.
