This demand surge is expected to remain strong as AI, 5G, and EV industries expand, each relying heavily on semiconductors with layered architecture.

RESTRAINT

Limited awareness and high equipment costs

Despite technological advancements, ellipsometers remain underutilized in several emerging markets due to high procurement and maintenance costs. The average cost of a standard spectroscopic ellipsometer ranges from USD 45,000 to USD 150,000, depending on features, making it inaccessible for small research labs and low-volume manufacturers. In Latin America and Africa, ellipsometer adoption is below 8%, primarily due to funding limitations and lack of trained personnel. Training to operate advanced models can take 2–6 weeks, depending on the device and application. Furthermore, maintenance contracts can add 8–12% annually to the equipment cost, deterring budget-conscious institutions. High initial capital outlay acts as a barrier to widespread deployment in sectors such as textiles, glass, and academic research in developing nations. Even in developed economies, public universities often share access to one unit across multiple departments to manage costs, which limits routine experimentation.
