2. The film thickness uniformity of deposited aluminum oxide is better than ±2% on 6-inch substrates;
3. Sample processing for sizes under 6 inches is supported, with a sample thickness limited to no more than 2 mm.

Ion Beam Sputtering (IBSD) is a thin film deposition technology. An ion source is utilized to sputter and deposit target materials (metals or dielectrics) onto the substrate, so as to form metallic or dielectric films. Since the ion beam is monoenergetic (ions possess equal energy) and highly collimated, it enables precise thickness control and the deposition of highly dense, high-quality thin films when compared with other Physical Vapor Deposition (PVD) technologies.

Periodic alternating multilayer films of silicon dioxide and tantalum pentoxide achieve antireflection for light at specific wavelengths.
2.Sample thickness shall not exceed 2 mm.
