Epi-ready CMP-polished magnesium aluminate spinel (MgAl2O4) substrates & windows (MgAl2O4, CAS 1306-44-1) wafers and diced research squares with sub-nanometer surface roughness for PVD, PLD, MBE, and ALD.
Precision-grown and chemical-mechanical-polished (CMP) in a Class 100 cleanroom, our magnesium aluminate spinel (MgAl2O4) substrates & windows (MgAl2O4, CAS 1306-44-1) substrates provide atomically smooth, epi-ready surfaces (Ra < 0.2–0.5 nm) for thin-film epitaxy, pulsed laser deposition (PLD), magnetron sputtering, molecular beam epitaxy (MBE), and optical characterization.
Isotropic cubic symmetry (zero birefringence) and broad UV-to-MWIR transmission (0.2–5.5 µm) make single-crystal MgAl2O4 spinel a versatile substrate for ferrite spintronics, silicon/III-N epitaxy, and rugged optical viewports. Standard research sizes include 5×5 mm, 10×10 mm, and 15×15 mm diced squares (0.5 mm or 1.0 mm thick) as well as Ø 1-inch, 2-inch, 3-inch, and 4-inch wafers in single-side (SSP) or double-side (DSP) polished finishes, packed in individual waffle trays or nitrogen-sealed cassettes with batch orientation and surface inspection data.
