In 2018，the US integrated circuit industry maintained a relatively stable development trend. Although the market size is still significantly behind the Asia-Pacific region，it continues to grow. The US continues to lead the development of the integrated circuit industry，with a leading global output value. Among the top 10 global giants，US companies occupy six seats and contribute nearly half of the global market share. The US integrated circuit design capability is far ahead，and it has monopoly position in the world of high-end integrated circuit products. The outward migration of manufacturing capacity is the weakness of the US integrated circuit industry，and the US government is taking various measures to vigorously promote the return of manufacturing. In the future，driven by the demand of 5G，artificial intelligence，and national security，the US will accelerate innovation and change in the fields of integrated circuit advanced technology and security chip technology，and will continue to play an important role in promoting the development of the global integrated circuit industry.
