A flat, thin piece of sapphire crystal known as a “wafer” is utilised in a variety of electronic and optical applications. Aluminum oxide (Al2O3) crystals are found in sapphire, which is prized for its toughness, tenacity, and optical purity.
The Verneuil technique, which includes melting and solidifying sapphire in a controlled environment, is commonly used to create sapphire wafers. Electronic devices including LEDs, power transistors, and radio frequency integrated circuits frequently use sapphire wafers as a substrate (RFICs). In high-pressure and high-temperature applications, they are also utilised as a substrate for optical devices such laser diodes, optical filters, and windows.
Because of their better mechanical and thermal qualities, sapphire wafers are chosen over other materials like silicon. They have a greater melting point, can tolerate higher temperatures and pressures, and are scratch- and wear-resistant.
The Global sapphire wafer market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For Silicon on Sapphire (SOS) wafers, Kyocera manufactures sapphire substrates in large quantities[1]. Worldwide, scientists and engineers rely on MSE Supply as a source of sapphire wafers because of the exceptional quality of their offerings.
On request, they provide customised sapphire wafers[2]. The largest high-quality sapphire wafer ready for the manufacture of LEDs is a 12-inch polished sapphire wafer made by Rubicon Technologies.
A full selection of premium sapphire substrates, including wafers and cores with dimensions of two, three, and four inches, six, eight, and twelve inches, are available from Rubicon[5].
Russian company Monocrystal is increasing the capacity of its monthly sapphire manufacturing from the present level of 4.0 million 2-inch wafer equivalents to 5.0 million units.
The sapphire substrate market in North America is dominated by companies like Elcon Precision LLC, AdValue Tech, S & D Materials, LLC, Rubicon Technology, Precise Micro-Optics Inc., NOVA Electronic Materials, LLC, GAVISH, and SVM.
The use of sapphire substrates in LEDs, laser diodes, and RFIC applications is expected to increase, and the market is expected to reach.
