Growing investment in 5G infrastructure
The growing investment in 5G infrastructure is expected to propel the market growth during the projection period. The deployment of 5G networks requires semiconductor substrates that can support the high-frequency and high-speed characteristics of these networks. Substrates used in base stations, antennas, and network equipment must provide low signal loss, high thermal performance, and compatibility with advanced modulation techniques. For instance, according to the most recent Omdia data, 157 million additional worldwide 5G connections were established between Q4 2022 and Q1 2023, with the number of worldwide 5G connections expected to surpass 2 billion. This corresponds to roughly one billion additional connections added yearly, demonstrating the tremendous scope and significance of 5G technology. Thus, driving the market revenue growth.
Complex manufacturing process
Semiconductor substrates often require sophisticated manufacturing processes involving intricate deposition, patterning, and etching techniques. The complexity of manufacturing can lead to production challenges, yield issues, and increased costs. The development of advanced semiconductor substrates requires expertise in materials science, nanotechnology, and semiconductor manufacturing. The technical expertise required to overcome these barriers may limit market entry for some companies. Thus, the complex manufacturing process is expected to limit the market growth during the forecast period.
Growing collaboration
The increasing collaboration among the key market players is expected to propel the market growth over the forecast period. For instance, in March 2023, Infineon Technologies AG and GaN Systems Inc. announced a formal agreement under which Infineon would purchase GaN Systems for $830 million. GaN Systems is a global technical leader in the development of GaN-based power conversion technologies. With unmatched R&D resources, application expertise, and a client project pipeline, the purchase of GaN Systems will considerably speed up their GaN vision. Furthermore, the merger will boost Infineon's position in Power Systems by allowing it to master all-important power technologies. Thus, propelling the market penetration.
Based on the product type, the global semiconductor substrate market is segmented into GaSb, InSb, GaN, Ga2O3, AlN, Diamond, Engineered Semiconductor Substrates and Others. The diamond semiconductor substrate is expected to hold a significant market share over the forecast period. The primary factors for the diamond Semiconductor substrates segment are strong thermal conductivity, improved high-frequency handling capability, and great energy efficiency and flexibility. Diamond semiconductor substrates boost the usage of multiple electromagnetic spectrums, which improves the performance of military and defense cellular phones, as well as satellite and wireless technologies.
Based on the application, the global semiconductor substrate market is segmented into photonics and electronics. The electronics segment is expected to capture the largest market share over the forecast period. The semiconductor substrate market is a dynamic and multi-faceted sector that serves various segments within the electronics industry.
These segments encompass a wide range of applications and technologies, each with unique requirements for semiconductor substrates. This segment includes devices like smartphones, tablets, laptops, gaming consoles, and wearables. Consumer electronics demand high-performance semiconductor substrates that support fast processing, energy efficiency, and compact designs. The substrates used in these devices need to be able to handle complex integrated circuits and provide efficient heat dissipation. Thereby, driving the segment expansion over the forecast period.
Based on the application, the global semiconductor substrate market is segmented into automotive, telecommunication, consumer electronics and others. The automotive segment is expected to grow at the highest CAGR over the forecast period owing to the growing demand for advanced features in the vehicles. Modern vehicles incorporate a wide range of electronic systems, including infotainment, navigation, ADAS, electric powertrain and autonomous driving technologies.
These systems rely on semiconductor devices, which in turn require suitable semiconductor substrates. On the other hand, the telecommunication segment is expected to hold a significant market share over the forecast period. The telecommunications sector is characterized by continuous technological evolution and growing demands for faster and more reliable communication. Semiconductor substrates are integral to achieving these goals, as they enable the creation of high-performance components that form the backbone of modern communication networks. As new communication standards and technologies emerge, the demand for specialized semiconductor substrates that can support higher frequencies, faster data rates, and enhanced connectivity will remain strong. Therefore, this is expected to drive the segmental growth during the forecast period.
Asia Pacific is expected to dominate the market over the forecast period. The market growth is attributed to the growing consumer electronics industry and the rising automotive sector. For instance, according to secondary analysis, Foreign direct investment (FDI) into the defense electronics sector is permitted up to 49% under the automatic method, and up to 51% with government permission. To encourage investors, including original equipment manufacturers (OEMs) and integrated device manufacturers (IDMs), the government of India has established an automated path for 100% FDI in the ESDM business.
Riding the green mobility wave, India has experienced a rapid surge in automobile electrification. In FY2022, India's EV sales climbed by more than 200 percent over FY2021. By 2030, the government hopes to have a 30% market share in the passenger automotive industry. Furthermore, the increasing investment by the market players is expected to drive the market growth during the forecast period.
For instance, in March 2023, Mitsubishi Electric Corporation stated that it would more than double its previously disclosed investment plan to roughly 260 billion yen during the five years ending March 2026, mostly for the construction of a new wafer factory to enhance the production of silicon carbide (SiC) power semiconductors. Thus, the aforementioned facts are expected to propel the market growth over the forecast period.
North America is expected to hold a significant market share over the forecast period. North America hosts a substantial number of semiconductor substrate manufacturers, semiconductor fabrication facilities (fabs), and research centers focused on semiconductor materials and processes.
