Regulatory and Policy Support

The U.S. CHIPS and Science Act, signed in 2022, is a significant tailwind for domestic semiconductor production, offering incentives for fabs and R&D in both integrated and discrete domains. Additional efforts by the Department of Energy and the Department of Defense are supporting innovation in power electronics and ruggedized components.

Challenges

Despite its positive trajectory, the U.S. discrete semiconductor market faces a few challenges:

• Global Competition: Asia-Pacific countries, particularly China and Taiwan, dominate volume manufacturing, putting pressure on U.S. cost structures.

• Raw Material Dependency: Supply chain disruptions and limited access to critical raw materials like SiC wafers or GaN substrates can affect production.

• Workforce and Skill Gaps: Advanced manufacturing of discrete devices requires skilled labor in semiconductor process engineering, which remains in shortage domestically.

Future Outlook

The U.S. discrete semiconductor market is expected to grow steadily through 2030, supported by rising electrification trends, government policy, and technological advancements in materials and packaging. As energy efficiency and power density become even more critical across sectors, discrete devices—particularly those using wide bandgap materials—will be essential enablers of next-gen electronic systems.

Key growth opportunities will arise from:

• SiC and GaN-based power semiconductors
