The compound semiconductor market is fraught with challenges, more notably manufacturing complexity and cost, which are serious deterrents against widespread adoption and scalability. Devices made from compound semiconductor materials such as gallium arsenide, gallium nitride, and indium phosphide, with respect to properties compared to silicon, include efficiency, greater frequency and power applications, and heat endurance.  Since the production route for these compounds is far more complex and resource-consuming compared to any silicon material alternatives, they face some challenges. One of the main contributing factors to a more complex production route is the requirement for specialized processing techniques and equipment.

For instance, gallium nitride semiconductors are generally grown on sapphire or silicon carbide substrates, where the conditions for crystal growth are so stringent for maximum perfection. These processes are extremely sensitive; even tiny deviations can lead to a faulty end product in terms of performance. Moreover, the wafers of compound semiconductors are mostly costlier than silicon wafers, which is generally due to the lack of availability and expensive raw materials. For example, a 4-inch gallium nitride wafer is several times costlier than the same-size silicon equivalent. Besides, the manufacturing process for a compound semiconductor usually involves a number of operations, like molecular beam epitaxy (MBE) or metal-organic chemical vapor deposition, which are both very expensive and labor-intensive, demanding high skills as compared to many other operations.

For instance, MBE involves depositing thin semiconductor material films in an evolved high vacuum environment, requiring specialized equipment that enormously increases capital and operational expenditures. This is another factor that makes the overall cost of compound semiconductor devices surge, further restricting their penetration in the mass market for production, especially in consumer electronics where price is an important consideration. Similarly, the cost factor is present in the manufacturing of GaAs-based semiconductors, which are also used in the field of optoelectronics such as laser diodes. The complex fabrication process, as well as the comparatively low yields owing to defects in the materials, renders such devices much more costly than silicon-based alternatives.

These inefficiencies of production, coupled with large up-front capital investments for setting up fabrication plants, result in extended return on investment timelines, dissuading investment in the technology. Moreover, although demand for compound semiconductors is on the rise in industries of telecommunications, automotive, and defense, such industries are usually dissuaded by the expense involved in large-scale production volume escalation to address large-scale demand. While compound semiconductors' advantages are evident, the issue of controlling manufacturing cost and complexity continues to be a major obstacle to their broad applicability across many industries.

Most of the industry leaders in the compound semiconductor sector attempt to keep their competitors behind by launching innovative products, collaboration and partnership deals, and merger and acquisition transactions. For instance, in November 2024, Nexperia launched its initial SiC MOSFETs with the availability of two 1200V discrete devices in 3-pin TO-247 packaging with RDS (on) ratings of 40 mΩ and 80 mΩ. Similarly, in October 2024, the U.S. Department of Commerce and Wolfspeed, Inc. entered into a non-binding preliminary memorandum of terms (PMT) to supply up to US$ 750 million in proposed direct funding under the CHIPS and Science Act. The suggested funding was for the development of a silicon carbide wafer production facility in Siler City, North Carolina.

Besides, in January 2025, Wolfspeed announced its Gen 4 SiC technology platform, which is designed to make switching behavior and design issues typically found in high-power designs easy. Available in 750V, 1200V, and 2300V devices, the Gen 4 platform would be shipped on 200mm wafers. Similarly, in February 2025, Infineon Technologies confirmed impressive advancements along its 200 mm SiC roadmap, with the first products built on the technology going out to customers in Q1 2025. Made in Villach, Austria, these SiC power devices are aimed at applications in renewable energy systems, trains, and electric vehicles.
