ASE Technology Holding Co., Ltd.

Every finished chip still has to be packaged and tested before it reaches a device, and ASE Technology Holding is the largest independent company doing that work. Based in Kaohsiung, Taiwan, it takes bare silicon from fabs like TSMC and turns it into usable, protected components, then confirms they function, a slice of the industry known as OSAT, for outsourced assembly and test. The holding company was formed in 2018 to combine Advanced Semiconductor Engineering, founded in 1984, with rival Siliconware Precision Industries. As chips push against the physical limits of shrinking transistors, advanced packaging, stacking and connecting multiple dies in one module, has become where a lot of performance gains now come from, which plays to ASE's strengths. Its customers include most of the big names in chip design.
