Semiconductor supply chain include all kinds of semiconductor manufacturing and design industries, such as IC manufacturing, IC packaging and testing, IC design, and discrete component manufacturing.

In 2020, Taiwan manufacturing output will decline by about 5%, but the semiconductor industry will maintain positive growth. Semiconductor refers to a material whose conductivity can be controlled. The upstream of the semiconductor industry chain is IP and IC design, the midstream is IC, wafer, mask or chemical manufacturing, and the downstream is the packaging and testing industry.
