Indium thin films are increasingly critical to the advancement of quantum technologies due to their unique physical, thermal, and electrical properties. At Intlvac, we specialize in high-performance indium deposition using precision Physical Vapor Deposition (PVD) methods to support the evolving demands of the quantum market. Indium films are used across a wide range of quantum and advanced semiconductor applications, including: - Quantum computing devices - Infrared focal plane arrays - Low-resistance ohmic contacts for III-V and II-VI semiconductors - DLC (Diamond-Like Carbon) Coatings Infrared anti-reflective and wear-resistant coatings. - Electronic component fabrication in cutting-edge semiconductor technologies Indium’s ductility, low melting point (156.6 °C), and thermal conductivity make it especially suitable for microelectronics and cryogenic environments required by quantum systems. Its compatibility with complex crystal structures also enables the formation of stable and reliable electrical contacts. Physical Vapor Deposition (PVD) offers superior film quality compared to traditional methods such as electroplating. PVD provides: - Better adhesion to substrates - Uniform and dense film structures - Reduced sensitivity to environmental conditions - Precise control over film thickness - Compatibility with a broader range of materials These advantages are crucial in quantum device fabrication where precision, consistency, and reliability are paramount. At Intlvac, indium films are deposited at cryogenic temperatures, which supports: - Higher shear strength at contact points - Improved adhesion of indium bumps to wafer surfaces - Inhibition of atomic migration during film growth - Reinforced columnar crystalline structure, enhancing mechanical and electrical stability This low-temperature deposition approach is vital in maintaining device integrity in low-temperature operating environments typical in quantum computing. We use negative photoresist in the lift-off process, which provides: - High selectivity during processing - Simplified patterning for multilayer deposition - Reduced risk of pattern distortion This method is ideal for creating intricate patterns such as micro bump arrays. Intlvac is committed to supporting the global growth of quantum technologies by providing: - Precision-engineered thin film coatings - Scalable solutions for research and production - Custom processes designed to meet the exacting needs of quantum hardware manufacturers
