Purchasing decisions weigh epitaxy reactor compatibility, bow/warp at temperature, and downstream dicing yields.

Two-inch wafers remain relevant for prototyping, university labs, and low-volume specialty devices. Their appeal lies in lower upfront costs, rapid iteration cycles, and the availability of diverse orientations. Suppliers compete on quick-turn delivery, tight minimum order quantities, and application engineering that helps customers shorten development timelines without compromising on defect density or surface finish.

Four-inch wafers balance cost and throughput for many established LED lines and select RF programs. They benefit from mature MOCVD hardware ecosystems and abundant process know-how, enabling predictable yields and stable supply. Growth is underpinned by lighting replacements, display backlighting, and retrofits where fab managers optimize depreciation and avoid disruptive tool changes.

Six-inch wafers enable higher capacity per run and better line productivity for scaled optoelectronics and RFIC manufacturing. Transition economics depend on reactor configuration, thermal management, and epi-uniformity, which together drive device performance and per-die cost. Vendors emphasize low TTV, superior crystallinity, and logistics reliability to support multi-site global operations and to de-risk expansion plans.

The “Others” category includes niche diameters tailored to specific toolsets or experimental architectures. Adoption is primarily customer-led, requiring close supplier collaboration on seed selection, boule growth parameters, and custom polishing.
