Diamond Semiconductor Substrates Market Size Projection (2024 - 2030)

The global diamond semiconductor substrates market, valued at USD 1.73 billion, is anticipated to expand to USD 4.02 billion by 2030, indicating a compound annual growth rate (CAGR) of 12.81% during the forecast period spanning 2024 to 2030.

Diamond Semiconductor Substrates Overview

Diamond semiconductor substrates consist of single diamond crystals. The manufacturing process involves creating a base structure that yields pillar-shaped diamonds made of single diamond crystals on one side of the substrate. Each pillar-shaped diamond facilitates the growth of a single crystal from its tip. Subsequently, the diamond substrate layer is separated from the base substrate to produce a diamond substrate, typically circular with a diameter exceeding two inches. Diamond stands out as an exceptional semiconductor substrate due to its remarkable properties, including high thermal conductivity, elevated electron/hole mobility, substantial dielectric breakdown field strength, low dielectric loss, and wide bandgap, rendering it unparalleled among semiconductor materials.
